Before you read the article and go to hack the nearest intercom, you need to remember the following: it is permissible to open the intercom not with a key, but by other methods only in the most extreme case, in case of urgent need. Hacking an intercom with criminal intentions is punishable by law.

These days on the doors of most multi-storey buildings Intercoms installed. They help keep the entrance clean and also ensure the safety of the residents of the house. But at the same time, they will not allow a person who does not have a key to get inside. And he may need to get inside for various reasons:

• lost the key to the intercom or forgot it at home;
• a person goes to visit, but does not know the apartment number;
• the owner does not have an intercom handset or does not work, etc.

How to open an entrance door without an intercom key

The easiest way to get inside is to call any apartment in the house and introduce yourself as a postman, plumber, locksmith, or simply explain the situation.

You can also try open the entrance door yourself. It is not recommended to break down the door physical sense, because in this case problems may follow with the residents and then with the police. You only need to hack the intercom.

Several ways to open intercom doors without a key

Secret codes for opening intercom doors

Visit

One of the popular ones are Vizit intercoms. You can open them using the following combinations: *#423, *#4230, 12#345, 67#890 . If there are no * and # buttons on the control panel, they should be replaced by C instead of * and K instead of #.

If these methods do not help, you can try to get into service menu.

First you need to dial 9999. If everything is correct, a short double signal will sound. After this you can enter the default code. This is 1234. If everything is correct, a short beep will sound, otherwise there will be a double beep. Then you can try to enter other codes - 6767, 9999, 12345, 0000, 3535, 11639.

If everything worked out and you were able to enter the service menu, you can perform the following operations:

• open the door: 2pause#pause3535
• enter your key: press 3, then place your key on the reader and wait for the beep.
• you can delete all keys from memory by pressing button 4

To confirm the changes made, press button 4. Exit the menu using the * button

Cyfral

One of the most popular are also Cyfral intercoms. To open them you can try several ways.

• If there are apartments in the entrance with numbers divisible by 100, you should enter the following code: call/apartment number, divisible by 100/call/2323 or 7272 or 7273
• If the model name contains the letter “M”, you can try the following codes: call41, call 1410 or 07054.

If the intercom model is CCD-2094.1 M, you need to open it using a different method. You should dial "call0000". Either the door or the service menu will open immediately. In the latter case, ON will appear on the display. You need to press button 2, after which the door will open. If the message OFF appears, this will mean that the installation of the intercom was carried out experienced specialist, which disabled the ability to quickly log in and changed the codes.

Metacom

There are also several ways to open doors protected by Metacom.

• call - number of the first apartment in the entrance - call. COD appears on the display. Now you need to dial 5702.
• 1234call6call4568.
• 65535call1234call8.

Metakom MK-20 M/T opens a little differently. You can try the combination call27call5702 or call1call4526

Eltis

Eltis intercoms are considered one of the less reliable, but they are still very difficult to open without a key. To do this you should try the following codes:

• call-1234-2-1-3-3-123
• call100call7273
• call100call7272
• call100call2323

If nothing worked with the number 100, 200 is dialed instead, then 300, etc. If there is no result, it means that the factory settings were changed during installation. In this case, you should press the call button and wait. After twenty seconds, a number of five characters will appear on the display. You should remember it and enter it according to the principle stated above.

If there is no result now, you should press and hold down any button for a few seconds. The display will show Code. Now you need to enter the standard password 1234. Func should appear. After this you need to press 1 and install new code. The number 2 will save it.

Another way is to try entering codes from Cyfral.

Keyman

One of the most difficult intercoms for lawbreakers.

There are only two known codes for opening doors protected by it, but with their help you can open only one of five castles.

• K-100-789-wait for sound signal-123456-8
• K-170862-wait for sound signal-0

The methods listed above can be used to open doors protected by intercoms of the most popular brands. It should be remembered that you should open the intercom only as a last resort and when absolutely necessary. Opening an intercom for criminal purposes is punishable by law.

Attention! Access codes are only suitable if the installers were lazy and did not change the default password. This happens quite often :)

Eltis intercoms

Initially, the default code is “1234”, but any company, when installing an intercom, naturally changes it to its own, and it is almost impossible to recognize it. To enter password entry mode, you must hold:
1) any number key for 7 seconds (menu "code" - menu for working on apartments, programming keys)
2) Button “c” - hold for the same amount of time (menu “sys” - general parameters, prohibition/enablement of codes - 1234 is quite often suitable for this menu, it worked for me 50 times.)

Explanation of menu operations:
1. Call the system menu "sys".
1) Press the “b” button and hold for 7 seconds.
2) After the inscription “SYS” on the display, enter the system password (stupid lazy system specialists often do not bother to change the password, which is the default - 1234)
2.1) If the input is correct, the intercom will display the firmware of the form “6_7x”, where x is the firmware number, after which the “_FUNC” menu will load.

From it press:
“1” - “PAS” will appear, after the input field for changing the old password to enter this menu (dial 4 digits and the intercom will return to “_FUNC”
"2" - menu "_ LOС" to enable/disable the general login password (buttons 1/0 respectively)
"3" - menu "_ dig" to change the general login password. Press 3, 4 or 5, "____C" will appear.

Depending on the button pressed, you can set a new password, 3, 4 or 5 digits, respectively. (type new password)
"4" - menu "_beep". This option turns on/off the signal for opening an individual apartment code in this apartment (the handset rings when opened with the default code, buttons 1/0)
"5" - does not exist
“6” - menu “_FLOC” for turning on/off individual entry codes for apartments (to check, press “in” in normal mode, if “F” lights up, it means it’s on)
"7" - does not exist
"8" - menu "_OPEN" - to change the duration of door opening (the number of signals will change, decrease/increase with buttons from 1 to 9)
"9" - does not exist
"0" - exit

2. Intercom serial number.

Press "in" and hold for 20 seconds. 5 digits will appear and then reset.
3. Input engineering code(system menu "CODE" for work on apartments)
1) Enter any NUMBER and hold until “CODE” appears, then a password entry field will appear.
2) Enter the system password (by default 1234 as in the first case)
3) If the input is correct, the firmware will appear, then the "_FUNC" menu.
4) From this menu:
"1" - Set a new password to enter this menu (same as the first case, see above)
"2" - Set a new general login password (4-digit).
"3" - work on apartment passwords:
"_FUNC"--> press "3"--> "F"--> enter the apartment number and press "c"-->"____C"--> enter a new code (but not 0000, because by entering it , you will prohibit the use of the code for this apartment)--> the apartment will be dialed--> ask to press the “open door” button TWO times--> the code is accepted, “_FUNC”.
“4”, “5” - menu “__ LF”, but different options are hidden under different numbers.
"4" - disable/enable individual handsets in apartments. Dial the apartment number, then press "in". “*** #” will appear, where *** is the apartment number, and # is the number 1 or 0 (on or off). Click the value you need.
"5" - key coding. Dial the apartment number and press the "c" button (see above). “***LF” will appear, where *** is the apartment number. Place the key against the reader. If you have not encoded the key before, the inscription “ADD” will appear; if you have encoded it, the number of the apartment to which the key is recorded will appear. After encoding, you can open the door with this key after logging out.
"6" - menu "__ dF". Option to delete keys. Type the apartment and press the "c" button. "_ dEL" will appear, press 1 - the number of keys that have been deleted will appear. (*dEL). Press 0 to exit to "_FUNC".

VIZIT intercoms

To open the door, you can try dialing *#423. (not always suitable)
Entering the service mode is quite simple:
#999 - beeps 2 times - enter the master code, default is 1234, if it comes up - beeps 1 time
if the code is incorrect, it will beep with a two-tone signal and the red LED will light up.
Explanation of operations (since there are few of them in service mode, the explanation of the buttons is given here:
2-setting individual codes for apartments
3-key programming for entry
4-erasing keys from memory
*-exit mode
#-confirm installation (save changes).
1,5,6,7,8,9,0 - does not exist.
Try to encode the key for yourself (an example is given if the master code is correct):
#999 (2 peaks) 1234 (1 peak) 3 (1 peak) (apartment number) attach the key (pick) # and then * .
VIZIT intercoms also have a special mode in which you can change everything, even the master code. The transition to this mode is carried out from the normal state as follows (taken from the instructions):
1) turn off the power to the intercom
2) disconnect the two “programming” wires in the central unit
3) turn on the power.
As can be seen from the above, the block with the buttons must be removed.

Nowadays it is difficult to find a house that is not protected by a special system. This wonderful device warns against uninvited guests. But what to do if you forgot the magnet at home or it stopped working. If this happened in daytime, you can wait until the neighbors open the door. What if at night? How to open the intercom without a key in this case? We have collected the most best tips to resolve this unpleasant problem depending on the brand and model of the intercom. Use it!

An intercom system is a security measure that is used for... It is used to connect the guest with the owner and is installed in and apartment buildings or offices.

With its help you can solve a wide variety of problems:

• the simplest system will help organize the entry of clients into an organization or guests into private housing;
• organize more complex system and the ability to record the history of events;
• additional device.

Over the entire period of using intercom systems, no one doubts their effectiveness. The question of choice is a financial question.

The principle of operation of the intercom system

The device is quite simple and consists of only a few components:

• call block. It is presented in the form of a panel protected from dust and moisture;
• internal zone, which includes intercom(call key, microphone and loudspeaker) and door station;
• locking lock;
• subscriber complex. It is made in the form of a tube and is installed either at the reception desk in the office. It contains: a control button, a microphone and a speaker;
• magnet with chip.

The intercom can be equipped with an audio or video signal. All elements are connected through a switch.

The intercom device works by analogy with a relay connection as follows:

• the guest presses the “Call” button on the external panel;
• the contacts are closed, the signal reaches the owner’s subscriber complex;
• the owner of the receiving device presses a button to negotiate;
• at the owner's discretion, he can either unlock the entrance system or refuse reception by pressing a button.

Manufacturers initially set a password to open the door mechanism. When installed at the owner’s discretion, it can be replaced either on the main unit’s remote control or via software.

How to open an intercom without a key: basic methods

If you don’t have a magnet with you, or it stops working, you need to contact your neighbors. You just need to dial their number on the device and explain this trouble. If they are at home, they will certainly provide access to the entrance.

But this situation does not apply to all cases of life. For example, devices are not installed everywhere. Or the systems are turned off. In this case, you can knock on the windows of your neighbors on the first floor. The owners will understand the huge problem and help you unlock the system.

What if you are the owner and you simply have no neighbors? Or another option - you returned at night, and calling someone is simply indecent? In this situation, you should use code.

There is no need to try to force entry into the entrance or break the dashboard. This will not help unlock the lock. In addition, in this case, the doors will not be unlocked from the inside, and you will have to pay for the repair of both the door and the intercom system. Even administrative penalties for petty hooliganism can be applied.

There are several types of keys available for modern intercom systems. Their main task is to open the entrance lock with installed security control. All of them are programmed with a specific factory code. If the firmware was changed during operation, in this case only Customer Service. After their intervention, it will be necessary to reprogram the device.

Firms that program locks use special technology opening devices:

• contactless;
• tablet-chip;
• all-terrain vehicle;
• universal key for intercom.

Using the latter, you can open up to 95% of models. It is easy to use, as it can be used to quickly resolve the issue of opening doors. These are the devices that service workers or postal workers use.

A key called “all-terrain vehicle” can also be classified as universal. Utility workers don't have to carry around large bundles of chips. It is enough to have one universal one. The software device is located in the chip; just touch it to the contact located on the input panel.

There is another way to open intercom devices using a universal key - a contactless master key. To do this, there is no need to apply it to the contact on the panel. The principle of operation is at a distance. It has one significant drawback - high cost.

How to make a universal device yourself

Such a device is not difficult to implement for someone who is familiar with programming and has the skills of a radio mechanical engineer. You need to know the model name. Information about which workpiece is suitable can be found on the Internet. There are also tables for combining the duplicator and blanks.

Making a new device takes a few seconds. To do this, you will need an “emulator” device. This is a device that opens almost all intercom systems, with a few exceptions.

But even the most professional master, the best software and emulator may not be able to handle some devices. You need to personalize the emulator for a specific version, then the cipher will be easily selected for this model.

How to open an intercom from well-known manufacturers if you forgot the keys

An excellent solution to the problem of how to open any intercom is a password. It is installed in the firmware. It should be clarified with the workers who installed the intercom device, or found on the Internet.

For many devices different manufacturers the same cipher fits. This applies to devices Visit or Eltis . But for new system Cyfral no password provided.

It is important! The password embedded in the intercom device program works even if it does not have a memory card.

In most cases, if the codes are programmed by the manufacturer, the passwords can work in all cities. Sometimes intercom systems can be encrypted by the installation company. Then you need to ask them for the password. In any case, services that require systems to be opened daily, such as postal workers, have the code. You can ask them for the password for the intercom device.

How to open the Vizit intercom without a key

This is the most common system. If the original firmware has not been changed, the algorithm for opening the “Vizit” intercom is as follows:

• 12#345;
• *#3423;
• *#4230.

Suitable for new Vizit devices:

• 67#890;
• *#423.

You can use the following codes to open the Vizit intercom without a key (suitable if it has not been opened before):

• #999—double ring, then service panel code 1234. If this dial does not work, there will be a double beep. If everything is fine - one beep.

If the service code is incorrect, dial not 1234, but the following options:

• 0000;
• 3535;
• 9999;
• 12345;
• 11639;
• 6767.

To determine whether the cipher is correct or not, a beep will help: if it is incorrect - 2 beeps, for a correct one - only 1.

When the menu worked with one call, you need to add your own code:

• to activate the lock: 2 – pause –#– pause – 3535;
• then you should add your own password: enter the number 3 and lean the chip against the panel, then # and wait for the sound of the lock operating.

Important! You must remember to delete all settings from the service settings memory. To do this, press 4 # *.

How to open the Forward intercom without a key

Manufacturers of these models often do not make their information publicly available. Only three sequences are known:

• 123 * 2427101;
• K + 1234;
• 2427101.

To include your password in the service settings, you must enter:

• 77395201 + * +0 *, place the chip against the device and press # twice.

If this sequence does not work, you can dial 5755660 instead of 77395201.

Intercom "Cyfral": how to open without a key

These are the most modern intercom models. If you don’t know how to open the Cyfral intercom without a key, then you should follow the following algorithm. It will work if the entrance has apartment numbers that are divisible by 100.

To open the “Cyfral” system, you must click:

• “B”, apartment number, which is divided by 100, then again by “B” (for example, B400B);
• then 2323. If it doesn't work, instead of 2323 press 7272 or 7273.

The question may also arise about how to open the Cyfral CCD2094 intercom. It opens a little differently:

• “Call”, then 41, or 1410, or 07054.

If the system does not work, you should continue this way:

• “Call”, then 0000.
• If we get to the “Menu”, but the doors are still closed, we should press number 2.

If there is a problem with how to open the “Cyfral CCD 20” intercom, all the methods listed above will be suitable for solving it.

How to open the Eltis intercom without a key

It is quite difficult to work with this system without a chip. The password may not work for all devices. The algorithm of actions is as follows:

• V 100 V 7273.

As an option, enter not 7273, but 2323.

Another way to open the Eltis intercom without a key: the technique used for the Cyfral model is suitable.

How to open the Factorial intercom without a key

Factorial models can be opened by dialing 000000 or 123456. Alternatively, dial 5 and hold until the dashboard text message. Then you should enter 180180 and “Call”.

This is the rarest device in terms of encryption without an access key. The procedure is as follows:

• K – 100 – 789 – short beep – 123456 – 8;
• K – 170862 – short beep – 0.

Difficulties with the Blink system

Unfortunately, there is nothing to help in this case. These are not entrance intercom systems, but individual ones, which are produced for individual houses or houses with a concierge. There is no universal code for such a system. Please contact customer service for assistance.

Codes for the DomoGuard device

This is a fairly rare model. To open you need to dial:

• “C”, beep, code 669900 and “Call”, then the number last apartment in this entrance +1.

The sign “F-” should appear on the display. We get into the service settings. After this, you need to perform the following algorithm:

• 080 – open the lock;
• 333 – remember password;
• 071 – disable automatic blocking.

Intercom system "T-Guard"

For this model, the following algorithm should be performed:

• on the panel, click “Call” or “Call”, enter 00000, twice on “Call”.

All actions should be performed with maximum speed, otherwise the intercom device will not work.

Rainmann system

To activate the device you need to dial:

• “Key”, code 987654. After the call, dial 123456.

If everything is correct, we are in the service menu, the P icon will appear on the display. To unlock and open the lock, press 8.

How to open an intercom without a Metakom key: codes

For of this device the following will do:

• “B” (CALL) – the number of the first apartment in the entrance – “B”. “COD” will appear on the panel. Next 5702;
• 65535 – “B” – 1234 – “B” – 8;
• 1234 – “B” – 6 – “Call” – 4568.

The following combinations are suitable for Metakom-20 M/T:

• “B” – 27 – “B” – 5702;
• “B” – 1 – “B” – 4526 – then for programming, place a blank key (not previously programmed) against the dashboard.

Conclusion

The proposed options for how to open a door without an intercom key can be used if the manufacturer’s primary parameters were changed during installation. In addition, it is important to know which manufacturer’s device is installed in the house. The use of these algorithms can be used in the rarest cases; their use for mercenary motives can be criminally punishable.

In this video, professionals share tips.

02/24/2016 11/19/2019 by Why

Everyone knows that utility workers open the intercoms of a huge number of houses without carrying around a huge bag with keys to all these devices. They use the entrance to the programming mode, in which opening the door is far from the most complex function.

Manufacturers do not pay enough attention to complicating access to the program mode, as a result to an ordinary person who does not have special professional skills in programming electronic devices, it becomes possible to provide keyless access to entrances residential buildings equipped with intercoms.

This article is intended for use of information in an emergency situation, when it is impossible to open the door with a key (accident, accident, etc.).

Opening the intercom Visit

Intercom systems trademark Vizit are most often installed at entrances apartment buildings. The question of how to open an intercom without a key is relevant for people who cannot get into their own home. For keyless access to the entrance, you must enter a special code on the call panel that will allow you to gain access. When entering the code, you should take into account the version of the installed model.

Provided that the installers did not make any changes to the initial settings, we go through the following codes:

*#3423;
12#345;
67#890;
*#4230.
If the intercom does not respond to these codes, you need to go to the service menu. To do this, dial the combination #999 on the call panel and, after 2 short signals, the code. Again, there are many options for this code: 1234 (standard), 0000, 9999, 3535, 12345, 6767. If the code is entered correctly, the device will respond to it with 1 beep, and in case of an error it will give 2 beeps.

Once in the service menu, you can perform the following operations:

Open the door. To do this, enter: 2 – (pause) – # – (pause) – 3535.
Add your own key: enter 3 – attach the key to the reading location – # – wait for the sound signal.
Completely delete all keys from the internal memory: press 4.
To confirm the changes made, you need to press #, and to exit the service menu - *.

Opening the METAKOM intercom

Three ways to open METAKOM intercoms:

1. Press the call button - enter the number of the initial (first) apartment in the entrance - press the call button again - the word COD will appear on the display - enter 5702.
2. Enter 65535 – press the call button – enter 1234 – press the call button again – enter 8.
3. News 1234 – press the call button – enter 6 – press the call button again – enter 4568.

Opening of the intercom METAKOM MK – 20 M/T

The intercom from the same company opens somewhat differently - METAKOM MK - 20 M/T

There are 2 ways to disable it:

1. Press the call button - enter 27 - press the call button again - enter 5702.
2. Press the call button - enter 1 - press the call button - enter 4526.

Opening the Cyfral intercom

Two opening options:

1) If there is a mark “M” on the intercom.
Press: 07054, or – call – 41, or – call – 1410.

2) If there are three-digit apartment numbers.
Call – apartment number (100, 200) – call – 2323; 7272; 7273 (one of 3 numbers).

Opening the Eltis intercom (ELTIS)

There are only 2 similar ways to open intercoms from this company:

Press the call button - enter 2323.

Press the call button - enter 7273.

There are no other methods; if you fail, it means either you are doing something wrong, or Eltis has modified its devices and protection circuits.

Opening the Keyman intercom

The most problematic in access.
1) K – 100 – 789 – short sound – 123456 – 8;
2) K – 170862 – short sound – 0.

Opening Barrier II, 2M and 4

These are very old intercom models. And that is why they are often still found in old nine-story buildings and five-story Stalin buildings. You won't find anything like this in new buildings 100%.

In the “Barrier 2” and “Barrier 2M” models, to enter the entrance you need to press the buttons “1” and “3” or “1” and “0”. Sometimes you can open the door simply by moving a magnet in the area where the keys are placed. For model "Barrier 4" universal keys or there are no codes at all.

Rainmann and Raikmann intercom codes

Despite some similarity in names, Rainmann intercoms and Raikmann are completely different devices. Raikmann devices are resistant to hacking and cannot be opened without a key using a code. But the Rainmann CD-2000 and AO-3000 models are found.

In order to open the 2000th model, you need to click on the “key”, then enter the code “987654”. After this, the intercom will beep and you need to enter the numbers “123456”. If the engineering menu is available, the “P” icon will appear on the screen. Now, to unlock and open the door, you need to press the number 8.
It’s better not to reap anything else - you can cut everything off and get the hell out of the residents.

Another life hack that users have noticed is the reaction of the touch keyboard to hypothermia. If you roll a snowball, apply it and hold it for 15-20 minutes, then there is a chance to open the door.

Opening the Factorial intercom

Setting up intercoms of this brand is very, very similar to the already familiar Digital, with the only exception that when installing the device, it is necessary to change the master password and therefore it is believed that it will not be possible to open it. Although there may be a hacking option through the engineering menu. To do this, you need to dial the Factorial intercom code. In most cases the following are used:

000000
123456

Another option is to press the “5” button and hold it for 5-6 seconds, then type this:

180180 + “Call” + 4 + “Call” key.

Opening of the Laskomex intercom (Laskomex)

To open the door on Laskomex AO-3000 VTM, try entering the keys:

1 + "Key" + 8976
66 + "Key" + 1989

Didn't come? This means the code was changed during installation.

To enter the service menu, you need to click on the key 5 times, after which a password entry field will appear. The default is: 1234. Most often, it is changed during installation, but there is still a chance. Code P8 is responsible for opening the door “Laskomex AO-3000VTM”.

Opening the DomoGuard intercom

A rare guest in our high-rise buildings. It is extremely rare.

To open the Domogard intercom door, make one long press on “C”. After it makes a sound, quickly enter the code:

669900 + “Call” + number of the last apartment in the entrance plus 1

After this, the following message will appear on the screen: “F-”. We're inside the service menu! Then you can use one of the following options:

080 - Open the door
333 - Remember new key
071 - Disable door lock

Opening the Blink intercom

These are not entrance intercoms, but individual ones, used most often in private homes or where there is a concierge. There are no universal codes for it.

Opening the T-Guard intercom

Another rare model. There is only one hacking option:

“Call” + 00000 + “Call” + “Call”

The last two calls must be pressed quickly and the entrance intercom will open.

Opening the Forward intercom

There is very little useful information on Forward intercoms on the Internet. There are only three known universal keys that were unearthed:

123*2427101
K+1234
2427101

In order to program your door key for “Forward”, you can try entering “77395201”+”*”+0+”*”. After that, apply the key tablet and press “#” twice. If the code “77395201” did not work, try this one: “5755660″.

Opening the intercom KS-intercom

There is very little information about how to open a KS intercom. The only code I could find:

“K” + “377” + pause + “698” + “K”

There is also information that sometimes the code works:

"K"+0000
"K"+9999

Or:

"K"+ 0000 + pause + 98
"K" + 0903 + pause + 98 + pause + "K"

Unfortunately, they don't always work either.

Opening the Tehkom intercom

There is information on the Internet that it will not be possible to open the Techcom door so easily. In some cases, the following may work. You will definitely need a key for such an intercom. Press and hold three buttons “1”, “6” and “0”. After that, we release them one by one. We start with “0”, then “6” and “1”. A signal will sound. Here we enter the default pass - “4321”. If the password is correct, click on “Call”, then on “3” and again “Call”. We bring the key and the door will open. I haven’t tested this method myself, but I can’t vouch for it.

Opening the Impulse-DS intercom

There is very little information on Impul-DS intercom models. Possible options:

"1234"+"C"
“B”+”99911″+”B”

The first option almost never works, because... The code will definitely be changed when installing the device.

Opening the Berkut intercom

The entrance intercom Berkut LS 2001 is the only model of this manufacturer on the market so far. It is a simple device based on an oscillating circuit, which is assembled with a resistor and capacitor. Universal codes

“key” + 123456 + “key” + 5150С
"key" + 123456 + "key" + 206C
“key” + 123456 + “key” + 6140С
"key" + 123456 + "key" + 2589C Opening of the Pierres intercom (Pierce)

In the entrances there are models “Pirrs 1000 Micro”, “Modern” and “Lux”. Factory master code for all three types:

"12345678"
"K"+"1234"

Also for the Pier 1000 Micro model the key may work:

“8310649” + “entrance number”

There is evidence that these models of audio intercoms allow you to enter your own code. This is done like this:

Enter the master code “12345678”. If it has not been changed, a beep will sound. Press the door open button, and without releasing it, press the number “5” on the keypad. The confirmation signal for entering the settings should sound again. Release the door open button. Now you need to enter your code - 987, for example. The main thing is that there should be no more than 8 digits. Moreover, the sequence of the first two digits should not coincide with the master code or the apartment number in the entrance. After finishing entering the code, click first on the “star” and twice on the “hash”. After this, the intercom can be opened with the code: “987” + “*”.

Attention! If you tried to use the code specified in the article for your intercom and it did not work, there is no need to write angry comments. I make no guarantees. What works in one entrance is not a guarantee that it will work in another. In addition, in Lately installers became smarter and, having had enough of problems from young hackers, began to change passwords and master codes.

Information on opening intercoms

As you know, to set up an intercom you need to gain access to the programming mode. This is usually done by typing the password on the numeric keypad. After entering the installer mode, the specialist who dialed the code has the opportunity to both open the door with the intercom and change any system settings without opening the door.

It is this part of the system that manufacturers have devoted Special attention. However, the implementation of security system control is not always reliable, which allows you to both open an intercom without a key and hack into intercoms of any brand.

This happens most often not because of manufacturer errors, but because of laziness or inattention of the installer. Service codes of intercoms, or - as they are also called - secret codes of intercoms, are set by the manufacturer and are the same for all models. Installers do not change these codes when installing and configuring the system, which allows, in most cases, to open intercoms without a key or the use of special equipment.

Let's make a reservation right away: this is not a FAQ on hacking intercoms, which contains all the intercom codes. The universal reference book that we offer in this article contains only those codes that allow you to simply open the intercom without a key. We will not provide master codes for intercoms used to change system settings, just as we will not reveal some other secrets of intercoms.

And the main thing is for each of the readers to clearly remember: opening an intercom if necessary is an acceptable matter, and hacking an intercom for personal gain is punishable according to the criminal code. So what if main goal If you were looking for material on how to hack an intercom, these were the intentions, then at the same time look for the latest edition of the Criminal Code of the Russian Federation.

In the article we will consider information on opening intercoms of the following types: Barrier II, IIM and 4; VIZIT ( different models); Cyfral (various models); Eltis; METACOM; Rainmann; DomoGuard; Blink; T-Guard.

But before we begin, it is necessary to mention one more thing: the universal code for an intercom of any type is a fiction; each manufacturer indicates its own code for opening an intercom. How to find out the intercom code? If the installer did not consider it necessary to change the master passwords, then the descriptions below will help to do this. Otherwise, you need to contact your installer for the code.

Hacking Barrier II and IIM intercoms

Ancient Soviet intercom of the "Barrier" type with a mechanical lock and a flat magnetic key now you can find it no more often than a mammoth. But anything can happen, and such an intercom may well be in some equally ancient house. For models 2 and 2M there is an unchangeable opening code - 1013. But, in principle, the intercom opens without problems with a pair of small magnets, which you just need to move around the area to apply the key.

Barrier - 4

The fourth model of this type of intercom is single-user; it was installed in entrances with concierges. Therefore, it will not be possible to type a permanent code, but you will have to tinker with magnets until the bitter end. The key of such an intercom contains three magnets.

How to open VIZIT intercom without a key

Visit intercoms are a little more difficult to open. The codes on them are significantly diverse. Often the * and # keys are missing from the keyboard, instead the C and K keys are used, respectively.

If the standard settings of such an intercom have not been changed by the installer, then the door should open when *#4230 or 12#345 is entered. Opens recently installed intercoms with visit code *#423 or 67#890

How to hack intercom vizit through the service menu: dial #999 – this is to enter the service menu, wait for two short beeps, then enter the master code (default 1234). The visit intercom, which is being hacked, should respond with one short squeak. If you entered an incorrect code, the signal will be two-tone. In this case, you can try standard variations of master codes - 6767, 3535, 9999, 0000, 12345, 11639.

After entering the service menu, you can either open the intercom visit or perform a number of somewhat more complex operations.

So, combination 2 - pause - # - pause - 3535 - command to open the intercom door without a key.

Button “3” is configured to program keys for the intercom. After pressing key 3 in the service menu, you need to attach the key to the reader, press # and wait for the beep. That's it, the key is entered into the intercom memory.

Button 4 erases keys from memory.

* - exits the current mode.

# - used to confirm changes.

It will be a little more difficult to open the “Visit” BVD-3xx intercom - without a display and indication LEDs. To open the door, you need to press 1 in the service menu. However, hacking the intercom is not always successful. The visit will be successful in the case of the BVD-34x model (with a left-sided receiver).

How to open the Cyfral intercom

To open the Cyfral intercom you need:

a) if there are apartments in the entrance with numbering divisible by 100 (100, 200, 300, etc.), then the code must be entered as follows: call key (code 1) call key (code 2). In place (code 1) you need to enter the apartment number divisible by 100, and in place of code 2 - 2323, 7272 or 7273.

b) for intercom models with the letter “M”, you can try the code “call key + 41” or “call key + 1410”. Sometimes the door opens if you simply enter 07054.

The CCD-2094.1M intercom needs to be opened differently. You can distinguish it by a burning or flashing line on the screen. If you dial the code “call + 0000”, either the door will immediately open or you will enter the service menu (ON on the screen), then you need to press 2, after which the door will open. If OFF appears, the Quick Entry mode is disabled. This means that an installer who has been installing Digital intercoms for a long time was working. Accordingly, he changed the access codes.

Intercom codes Cyfral CCD-2094M

To open an intercom of this type you need to dial the code “0000 + call key”. The display should show “cod”. You need to enter the code 123456+“Call” or 456999+ “Call”, sometimes the combination 123400+ “Call” is used. We wait two to five seconds. If “f0” appears on the display, then access to the system menu is open. To open the door, you need to enter code 601.

If you want to visit this intercom (or rather, its owners) regularly, then it is better to enter your own key into the intercom memory, suitable for the Digital intercom. To do this, press the call key and keep it pressed until a message appears on the display indicating that you have entered the service mode. Then press “five” and enter the number of the existing apartment in the entrance. The display should change to TOUCH. As soon as this happens, apply the key. If you come across a model with an old optical key, then instead of the apartment number you need to dial 600, then insert the key and press the call button.

How to open the Eltis intercom

Eltis intercoms, the codes for which are not varied, are quite easy to open. There are two options for service combinations that will ensure “neat hacking” of the Eltis intercom: “call key 100 call key 7273” or “call key

100 call key 2323". If hacking the Eltis intercom does not succumb to such combinations, you can try options from Digital intercoms.

How to open the METAKOM intercom

Hacking a Metacom intercom is done according to the following scheme: you need to press the call button, then enter the number of the first apartment in the entrance and press call again. “COD” should appear on the display. After which you need to enter the actual code - 5702. If this method does not work, then try the combinations 65535 + call button + 1234 + call button + 8 or 1234 + call button + 6 + call button + 4568.

And also about how to hack the Metakom MK-20 M/T intercom without dancing around the keyboard. In principle, this model does not and will not have a system of protection against the use of master keys. Therefore, if you bring a “tablet” without firmware to the intercom reader, it will automatically enter programming mode. If you don't have a tablet, you can persuade it to open using the numeric keypad. The Metacom brand MK-20 M/T intercom code can be “call button + 27 + call button + 5702” or “call button + 1 + call button + 4526”.

How to open a Rainmann intercom

Reinmann 2000 models, as well as those intercoms of this brand that have a dot on the left on the display, can be opened as follows:

Press the “key” button on the numeric keypad and enter the code 987654. The reaction to this operation should be a double squeak. Then enter the code 123456. The letter “P” should appear on the screen, which indicates that you have entered the service menu.

4 - lock the door;

6 - turn off the intercom;

8 - open the door;

How to open the DomoGuard intercom

DomogarD intercoms are a little more difficult to open. You need to hold down the C button and wait for the squeak. Then quickly enter the service combination - 669900, press the call button and enter the apartment number one unit larger than the last one in the entrance. The intercom will respond by displaying “F—“ on the display. It means that we are in the service menu. To open the door, dial code 080. To enter a new key into memory - code 333, to disable the door lock - code 071

How to open the T-Guard intercom

Hacking this intercom is the simplest of those proposed. Press “call button + 00000 + call button twice.” The main thing is to do the last two clicks very quickly. The door is open.

How to open the Factorial intercom

The system of these intercoms is similar to Digital. The service menu is entered after the 6-digit Factorial intercom code is dialed. Usually this is 000000 or 123456. However, installers claim that hacking the Factorial intercom is practically impossible, if only because the Factorial intercom code must be changed during installation - this is one of the mandatory service settings. But you can try this combination - press the “5” key until a service message appears on the screen (3-5 seconds), then dial 180180 + call key + 4 + call key.

How to open the Blink intercom

This is the only single-user audio intercom, widely used in Russian market. It has neither a screen nor a numeric keypad and is usually installed in houses with a concierge or in private cottages. Therefore, service combinations will not help here. An ordinary D9-0.1 battery will help - “Krona”, “Corundum” and the like. The European type of such battery is 6F22. So, we find under bottom panel false bolts of a strange shape - they exactly correspond to the Krona connector. We attach a battery to them - and voila, the intercom is open.
