Door locks: installation by yourself. Selecting the lock for the front door. Replacement and repair of door locks

The process of inserting a lock is a simple matter, especially if the lock design is simple, and the door is the most common. Anyone can cope with this task, but on condition that you know what a chisel and hammer is.

Consider the main types of door locks. By the type of fastening they are infeed and overhead.

Mortise door locks

It is often the door lock mortise is installed on metal doors. In the wooden this place will be weak and vulnerable. The door lock is embedded in the door directly.

When making a choice, it is very important to pay attention to the thickness of the faceplate of the lock, it should not exceed the thickness of the door itself and its depth. Such locks are used both for left-side structures, and for right-handed ones. In addition, there are door locks, the installation of which does not depend on which way the door opens. The main advantage is that they can not be broken.

Overhead door locks

They have this name due to the fact that they are superimposed directly on the door. For self-installation, you do not need any special skills, and the process itself will not take long. Most often, these locks are used in combination with other types, for example, a lever. To strengthen the protection use a latch or chain.

By the type of locking mechanism, all the locks can be divided into three groups: thumbs, cylinder and electromechanical.

Locked locks

This type is today considered the most reliable, if you compare it with other types of locks. In this case, reliability is completely dependent on the number of sovals. These are the so-called plates, which are turned by a key and lock the lock itself. The more of them, the more shelter is better protected from hacking.

Despite all the advantages, such a castle has a disadvantage, which is in size - they are large enough. This makes it impossible to use the lock lock in the thin entrance doors.

Also, some inconvenience can be during the use of the key itself, it is also large, it is inconvenient to carry around with it. Some lock locks are equipped with transcoding blocks. This function allows you to change the key in case of need, the replacement of the lock in this case is not required.

However, the disadvantages of this type of constipation are so petty in comparison with all its merits, that it is still quite profitable to use it. Often, locks are equipped with 4-5 sovalds, which makes them reliably protected from drilling, sawing or other methods of breaking.

Cylinder door locks

Cylinder samples have in their structure a cylinder, or larvae for door locks. This type of constipation is quite reliable, because it is protected from using skeleton keys.

The cylinder lock can have key holes both on both sides and on one side. In the second case, there is a turntable on the "inside" side, which allows you to open and close the door without using a key.

For mounting in the door itself, it is necessary to make a hole so that the larvae for the door locks are not visible (to avoid burglary). To avoid possible knocking out, additional pads are used, which are located from the inside.

This type of door locks has its drawbacks, for example, there is the possibility of mechanical breaking, breakdown of the system, as well as dependence of performance on humidity and temperature drop.

Electromechanical door locks

Smartlocks, or "smart" locks. They consist of mechanical and electronic parts. In the event that the battery charge is over and the electronic opening of the lock is impossible, you can always use an ordinary key. Electromechanical representatives can be equipped with a digital panel, a chip key, systems that are designed to recognize the retina or fingerprints.
