Buy mortise locks for interior doors in the ZamkiTut online store at affordable prices.

Any door in your house or apartment should close tightly. Mortise locks, which you can buy in our store, are mounted inside the interior or entrance door. We have selected exclusively high-class security locks for you. An interior mortise lock is perfect for installation on a door of one type or another.

The price of a locking mechanism depends on its design. The versatility of the models is confirmed by the fact that the locks can be installed on any door leaf made of plastic, wood or metal.

Main advantages

High quality, reliability, reasonable cost and, importantly, ease of installation and operation. In order to install the lock into the door leaf yourself, it is enough to make holes using a drill or grinder. Next, install the lock and attach the handle to it. On the other hand, even a high-quality lock can become weak if it was installed by unqualified specialists.

Other benefits:

  • original appearance;
  • protection from external negative factors, which affects the durability of the structure;
  • reasonable prices.

Online store door locks offers cylinders (cylinders) for imported and domestic producers. The range also includes half-cylinders, oval cylinders and turn signals for cylinders (turntables).

The secret part of a cylinder lock is the cylinder or cylinder of the door lock, a product of precision technology. The lock cylinder is fixed inside or outside the lock itself and can only be turned with a key inserted into the hole. The secret mechanism is usually located in a standard case, thanks to which cylinders from different manufacturers can be interchangeable, i.e. they are compatible with each other. Lock cylinders are very common nowadays because of their ease of use (small size key, low turning force when rotating, also the main plus is that if necessary, not the entire lock is changed, but only the lock cylinder - its secret part. Large Reinforced cylinder mechanisms and cylinders with protection against most known methods criminal autopsy.

One of the types of lock security mechanisms is the cylinder mechanism. The structural element of the lock, of which the cylinder is a part, can only be activated when the original (standard) key is inserted into the lock hole. This category includes pin, disk, frame, magnetic and some special security mechanisms. All manufacturing companies produce cylinder mechanisms of the same shape, thanks to this “larvae” different manufacturers interchangeable with each other. This fact determines the enormous popularity of mechanisms of this type in the segment of household locks.

The main advantage of cylinder mechanisms is the ease of replacing or repairing the lock. If the need arises to change the lock, it is enough to replace only the central secret mechanism - the cylinder. The operating principle of this mechanism is to line up pins (needles) inside the cylinder in a certain combination, the pins take the configuration of the inserted key. Someone else's key will enter the wrong pin combination when opening the door, and the lock will not open. The secrecy of the lock directly depends on the number of pins, their manufacturing accuracy, as well as protection from unauthorized manipulation.

The protection class of cylinder mechanisms varies from first to sixth. It depends on the number of pins, security mechanisms, case material, and additional anti-vandal features. When installing the mechanism in the lock, it is possible to complete it additional protection- armor plate.

Our online store represents only the main the lineup cylinder mechanisms. If you want to buy a cylinder whose model is not on our website, you can always contact us and order the model you need.

In our online store you can buy lock cylinders and other locking mechanisms at affordable prices and at any time convenient for you.

A lock is a part of a door that protects a room from outside intrusion. Door locks require constant monitoring and maintenance. However, even with timely care of the device, various malfunctions may occur, which can be eliminated on your own. What to do if the door lock is broken? A detailed answer to this question can be found by reading this article.

If the front door lock is broken

  • suvaldnye. The device works by arranging metal plates, called levers, in a certain order;
  • coded. They are most often used for entrance doors, as well as office and utility rooms.

The first thing you need to do when the lock breaks down is to find out what type of device is installed on the front door.

Typical breakdowns and how to fix them

Let's take a closer look at what to do if the front door lock is broken. Among the most common breakdowns are:

    1. the locking mechanism tongue does not fit into the strike plate. This door lock malfunction can occur for several reasons:
      • skew door leaf;
      • skewed door frame;
      • locking the mechanism with a padlock plate;
      • loosening and loosening of the locking device.
  • secure all fasteners with a screwdriver;
  • straighten the door and/or frame. The door is straightened by adjusting the hinges. If the problem is door frame, then the strike plate must be reinstalled in the right place;
  • If the tongue is blocked by an overlay plate, then the lock must be disassembled, the position of the locking device must be corrected and the plate must be installed in place.

All of the above work is carried out without the involvement of specialists.

  1. the door is difficult to open. Repairing the front door lock for this malfunction involves adjusting the door leaf and lock;
  2. jams door lock. The key is poorly inserted and/or difficult to turn. This breakdown most often occurs due to clogging of the mechanism. To fix the problem, you need to:
    • carefully disassemble the mechanism;
    • clean all internal elements. To carry out cleaning small parts use a hard dry brush. Larger parts are wiped with a rag;
    • lubricate the device;
    • assemble the mechanism and carry out several opening cycles to systematically distribute the lubricant.
  1. jamming of the locking device. This problem is the most serious. To fix it, you will need to replace the secret part of the lock.

Replacing the lock levers

Many lever locks can be reprogrammed by the user. The reprogramming process involves changing one or more lever plates. If the locking mechanism has such a function, then it is necessary:

  • purchase a new set of levers. New keys are included with the kit;
  • sort the plates by identity;
  • for ease of further installation, mark each pair of levers;
  • install the bolt post into the lock body;
  • install the levers according to the diagram that is attached to the kit or using the selection method, relying on the free movement of the key;
  • assemble the lock and check its functionality.

The process of replacing the lever lock plates is discussed in more detail in the video.

Replacing the cylinder lock cylinder

How to repair a cylinder type door lock if necessary? For this you will need:

  • new secret part of the locking mechanism. To select the correct lock cylinder, it is recommended to first disassemble the device and measure the parameters of the central part. The easiest way is to go to a specialized store with the cylinder removed, where the sellers will independently select the desired device;
  • crosshead screwdriver.

Do-it-yourself lock repair, which involves replacing the cylinder, is carried out according to the following scheme:

  1. On the end side of the door, at the location of the lock bar, there is a bolt that secures the secret part of the mechanism. In order to remove the cylinder from the lock, it is necessary to loosen this latch using a screwdriver;
  1. after loosening the fasteners, the cylinder should easily come out of the body;

If the cylinder cannot be removed from the body, then you need to insert the key, turn it half a turn and pull it slightly towards you.

  1. measure and purchase a new cylinder and a set of keys, which is attached to the secret part;
  1. insert the cylinder into place and secure it with the fastening bolt;
  1. check the functionality of the lock.

Repairing a rim lock also depends on the type of device and is fully consistent with the diagrams described above.

Combination lock repair

To repair a combination lock, different situations you must be guided by the diagrams presented above. Reprogramming of a mechanical device is carried out according to the following scheme:

  1. The lock is removed from the door and disassembled. To do this, simply dismantle the button panel;
  2. under each button there is a plate that activates the locking mechanism;
  3. the plates, which are directed with an oblique part into the lock, are active;
  4. To change the code you need to turn it over acting plates to the edges of the lock, and those that will take part in the code combination, to the center of the device.
  1. assemble the lock and install it on the front door.

Recoding of electronic locks is carried out without removing the device using the lock control panel or a special key included in the kit.

Breakdowns of interior door locks and ways to fix them

The door lock is broken interior door? The first thing to do is to identify the cause of the breakdown. The most common problems include:

  1. sinking of the locking device tongue. This type of failure is most often caused by the spring holding the tongue. To make repairs interior lock, necessary:
    • disassemble the lock;
    • change the spring;
    • assemble the mechanism.

All work can be done without removing the lock from the door.

  1. repair of the lock handle due to loosening of the device is carried out using a screwdriver required diameter. Before fastening, it is recommended to clean and lubricate the locking mechanism;
  2. jamming of the locking latch. How to fix a lock on a door similar situation? The causes of the malfunction may be:
    • displacement of the internal elements of the device. The problem can be corrected by disassembling the lock and correcting the displaced elements. In some cases, they may need to be replaced;
    • deformation and/or natural wear of locking mechanisms, formation of cracks. To eliminate the problem, replacement of unusable elements is required. To make a replacement, it is recommended to contact a store where experienced employees will help you select components.
  3. If a lock with a key is installed on the interior door, it is worth reading above how to repair such a device.

In most cases, lock repair does not take much time and does not require special knowledge and skills. To locking device served for a long period of time and did not break, it requires constant care, cleaning the locking mechanism from dirt and dust and lubricating it.

There are many types of locks on the locking mechanism market: lever, deadbolt, electronic. A common model is a mortise door lock with a cylindrical mechanism, due to its high degree of security, maintainability and affordable price.

What is a cylinder lock, types of structure

According to the GOST standard, a cylinder lock is: “a mechanism that moves and fixes the lock bolt in working positions and ensures the secrecy of the lock through a secrecy mechanism, i.e. a set of specific combinations of pins (plates, disks) corresponding to its own key.”

These mechanisms have different forms:

  • Cylinder.
  • Circle.
  • A drop.
  • Triangle.

On the market door hardware cylinders with a European standard mechanism are presented: they have a certain size and are made of brass profile. Cases are made for them.

There are two types of cylinder mechanism:

  • Pin.
  • Disk.

Pin cylinder lock device

A pin lock, mortise cylinder (cylinder, volute) is a mechanism based on a core with a connector. It has code channels in which there are code pins (their height determines the number of slots on the key) and a spring that pushes the code pins out of the channel. The code pins are located in a profile, thanks to which they do not fly out. There are also support pins.

When the key enters the hole, each slot corresponds to a code pin, which is recessed to a certain depth (height). When unlocked, the code and support pins are exactly in line between the body and the core, and it (the core) turns easily. In this case, the code elements remain in the core, the support elements with springs remain in the housing. That's the whole working principle.

The cylinder shape (cylinder) adopted by the European standard is called: DIN standard mechanism.

Pin cylinder lock parts:

  • Frame - outer part the castle in which all the parts are located.
  • The key is an independent unlocking part, with the help of which the secret is opened when the leash is turned.
  • The cylinder or rotor is a replaceable part of a lock with a connector. It contains pins.
  • Code pins or pins are parts of the locking mechanism.
  • Locking pins or pins - together with code pins block the rotor.
  • Return springs - they are used to lock the pins.
  • Leash - with its help the bolt moves.

Disc cylinder lock device

A door disc lock is a type of cylinder device whose mechanism is represented by a set of discs. Each disc has a uniquely shaped cutout. Corresponding slots are made on the key.

When unlocked, the mechanism disks move deeper towards the core. If the key fits, it turns easily. The secret of the lock places the discs at a certain angle, their recesses create a channel with a balance - turn and the bolt moves.

The key is a lengthwise sawn rod with slots; it is also called a semicircular key.

Cylinder padlocks with this mechanism are less susceptible to freezing. It is not recommended to install a mortise disc lock outdoors. They are suitable for fabrics with heavy loads. Suitable for entrance and interior doors made of metal, wood, plastic, glass.

Types of cylinder mechanism

There are several classifications based on different criteria.

By location on the canvas:

  • Overhead – has one connector. On the other side there is a handle.
  • Door mortise lock– its connector is through, that is, the key can be used on both sides. The cylinders of this lock are of two types: key+key, key+handle. The second type (with handles) is more convenient, but the first type is safer: if with inside Insert the key into the slot; the lock cannot be opened from the outside.

In addition to these characteristics, there are cylinders of different lengths, the size depends on the thickness of the blade. When purchasing, you need to consider the size or you may encounter the following problems:

  • Cylinder small size– will be located deep in the body. This is ugly and inconvenient - the door will be difficult to open, because the key will not reach the mechanism of the device.
  • A large cylinder - if it protrudes beyond the edges of the connector, this will make it easier for attackers: it’s easier to break. If armored pads are installed in the housing, the cylinder will not fit into the socket.

Cylinders are classified according to their location on the body: central and outer.

Cylinder locks with latch

The mortise lock with a latch is functional and easy to use.

Cylinder locks with latch latches are closed under mechanical action. It is an auxiliary element of the locking mechanism. The latch is available with or without a tongue lock, with one or two handles. Such locks are often used in residential and industrial premises.

Hazel handles are used for entrance and interior doors. There is no functional features, it's more of a decorative element. The convenience is that when changing the interior, in order for the locking device to fit into the image, you just need to choose a handle according to the style.

Handles for entrance doors resistant to external influences, made of durable materials (when compared with interior ones).

Depending on the type of handle pressed, there are:

  • Push (for entrance doors).
  • Pivot (for interior doors).

The push handle is also suitable for interior designs. The choice depends on the buyer's preferences.

How to choose a cylinder lock

In addition to such a criterion as the size of the larva, when choosing, you need to pay attention to the following characteristics:

  • Protection – you need to ask your sales consultant how durable the material was used to make the lock. The difficulty of opening it when bumping, drilling, or selecting a key depends on this.
  • Quality - how accurately the mechanism is built, whether there have been any cases of breakdown, how repairable the mortise lock with latch is.
  • Additional functionality: this is recoding, installation of a gear mechanism, “anti-panic” and others.

The safety of the premises depends on how conscientiously the manufacturer adheres to these characteristics. How more reliable device– the higher, as a rule, its cost will be.

A cylinder mortise lock with a latch is convenient because, if necessary, it is not necessary to dismantle the entire device - it is enough to replace the cylinder. You can replace the lock cylinder yourself by following the proposed algorithm:

  • Open the door, find the screw on the bar near the cylinder at the end.
  • Unscrew the screw.
  • If the locks have handles, the cylinder can be easily reached; if without, you need to insert the key into the slot, turn it counterclockwise until it stops and pull it towards you.
  • Then move the key and handle slightly in the opposite direction so that the lever moves down - then the cylinder will easily come out of the body.
  • The new cylinder is inserted into the mechanism by the handle, or by inserting a key into it. Monitor the position of the lever - it must be completely secret.
  • Try to close the mortise lock with the latch, moving it backwards and forwards so that it closes freely.
  • Replace the screw.
  • Check the work.

To replace the cylinder of the rim lock, the body must be removed from the blade. Then everything is the same as with the previous one - find the screw, take out the old cylinder and replace it with a new mechanism.

How cylinder devices are hacked

Unfortunately the cylinder mortise lock is at the same time its weakest part - attackers use many methods to hack the mechanism. Here are some of them:

  • Hacking with a master key: pick up the key to the lock with modern mechanism It’s almost impossible, but thieves use special locksmith picks, plus technical devices, such as a bumping machine. True, this option may also be ineffective: the technology provides for a complex secret: grooves, grooves. Therefore, to open a mortise mechanism with a latch, it will take a lot of time, which attackers most often do not have.

  • Breaking out the cylinder: select a key of suitable size that will fit into the well. Then they hit it with a hammer - all the parts (pins, pins) are knocked down and the canvas opens. But this method is suitable if the lock is old or made of fragile material. You can protect yourself from such a break-in by purchasing a durable mechanism or choosing a lock with a non-standard connector.
  • Drilling – effective method hacking You can only resist by choosing a device with a mechanism made of high-strength materials.
  • Knocking out: using physical strength, improvised materials break the mechanism. The solution is to purchase strong structures.

The strength of the material is the main factor protecting the room from unwanted penetration. But you also need to remember that a mortise lock should be easy to use and last a long time.

Types of keys for cylinder lock

A mortise lock with a cylinder type latch is the most common. Such a device is distinguished not only by the type of fastening (mortise, overhead) but also by the type of key. Some are easy to copy, but there are models that cannot be taken from, and have millions of possible combinations.

  • English is an unreliable option, because it is a very common type. Due to the simplicity of the device, you can pick up the key, which makes the task easier for attackers. Easily broken. Such a lock can be installed at the entrance to a room that has no material assets.

Watch the video for more information about the features of the cylinder lock:

  • The Finnish key is a high indicator of reliability. The mechanism uses discs with slots, which are coded parts. Used in padlocks.
  • Profile key – has high level secrecy, resists master keys, easy to use. Has pins (active and passive), a large number of combinations.
  • High security key - 3D technology is used in the manufacture of some models. The mechanisms are difficult to hack and require tools and training.

For modern locks with handles, the last two types of keys are more often used due to their high degree of reliability.
