How to change the door lock

Replacement замка может потребоваться по разным причинам. Чаще всего это, конечно, его поломка. Также замки меняют, когда они перестают удовлетворять владельца. Например, старая система ненадежна и легко поддается взлому. При потере ключей также производится установка новой конструкции (хотя проще заказать дубликат). В статье мы поговорим о том, как поменять дверной замок в квартире самостоятельно, как сменить язычок и личинку.

Types of locks

Locks are:

• mounted;
• mortise;
• overhead.

Mortise locks are often installed in wooden doors. However, today they are put in steel structures.

Mortise locks do not provide an adequate level of security.

Padlocks and overhead locks - the most common. They are simply removed and replaced.

Locks differ not only in the method of installation, but also in their construction. Before you change the door lock, you must choose the one that will completely suit the owner.

1. Cylinder lock. This type of lock can not be completely changed if it satisfies the owner with its quality. In the event of breakage, it is enough to change the core of the structure, the so-called larva. That it contains the whole mechanism. The larva is a weak point of the cylindrical lock. If it is drilled, then the door will easily give in.
2. Level locks. Such systems are installed in only one way - a sidebar. For a layman to insert such a unit is problematic. To do this, you have to figure out how to hit the lock on the door without damaging the canvas. If the steel sheet, the lever lock can be removed and replaced with the same. Some companies produce locks of this type to be converted. The lock itself will not have to change, only the key to it will change.
3. Disk lock. These systems are divided into automatic and semi-automatic locks. They also contain larva. Most often, in case of breakage, such locks change, although, if the system is quite expensive, then you can do without replacing the core.

Replacement

1. The first thing to do is make the necessary measurements. It is better to dismantle the old castle and go with him to the store. However, this is not always possible. Therefore, it is necessary to establish the dimensions of the lock and find out its manufacturer. The old structure will still have to be removed, albeit temporarily.
2. Any lock has fasteners. Disk remove the easiest, but with the cylinder will have a little work. However, he can only remove the larva. This is done quite simply, it is attached to the side.
3. If you plan to buy the exact same lock that is already in the door, then it is enough to establish its characteristics and select the same one.
4. When the lock is purchased, it is necessary to dismantle the old one and try on a new one in its place. Fitting must be complete. A new system needs to be fixed and checked how it works. Before you install the door lock completely, you need to make sure that the system fits perfectly.

How to embed

Before you embed the door lock, you must select it. The easiest way to produce work with a cylindrical.

1. In order to embed the lock into the door leaf, you must first install a comfortable well height.
2. Now you need to attach to the canvas a new lock and make the markup. A groove will be drilled at the marking site. Tools will require a drill, chisel and chisel.
3. First, the work on drilling a groove is made by a drill with a drill having a slightly smaller diameter than the width of the groove.
4. Next, the groove is refined chisel and chisel.
5. Then you need to mark the hole where the hole will be drilled.
6. The holes for the screws are drilled last.
7. For the "secret" also need to drill out the groove. It is necessary to establish its size and make markup.
8. To determine how far the latch enters the groove, it is necessary to lubricate it with a dye and close the lock.

Before installation it is necessary to lubricate the moving elements of the lock. However, it is better not to touch the internal mechanism of the larvae. If necessary, it is better to process it with graphite. All other parts are treated with grease.

After installation, only decorative and cosmetic work remains.

How to choose

When choosing a door lock you need to consider where it will be placed. If it is a question of an entrance door in a multi-storey building, then the cylinder lock will also fit here. He, of course, can drill, but few of the robbers will make noise and attract attention. Modern iron doors are usually equipped with level locks.

In the cottage or cottage you need to put something more durable. It is better if the lock is not one, but at least two.

The strongest today are the so-called smartlock - "smart locks". Such systems run on batteries. Depending on the cost, they can be equipped with password buttons, fingerprint scanners or retina scanners. When the battery fully runs out, they function on a regular key.

The cost of these systems is quite high. They are used in the most extreme cases. By the principle of operation, they can be compared with intercoms, which today exist in almost every entrance.
