Repair of locks in the metal doors on their own

What to do if the lock broke? Call the master, try to repair the lock in the metal door yourself or just dismantle it and buy a new one?

Why the lock can break? The first and main reason for its wear, because man has not learned to create anything eternal yet.

Breakage can be associated with improper installation of a deadbolt or door, poor-quality assembly or defective parts in the lock itself, with the fact that someone tried to open it using a master key, or break the door.

Should I repair the lock

Repair of deadbolts in a metal door is possible only in the event of a minor breakdown, and even then, provided that the manufacturer has attended to the release of spare parts. Unfortunately, not all manufacturers do this.

But if you count how much dismantling, diagnosis of constipation, its bulkhead, spare parts purchase, repair and installation can do, then in most cases it turns out that it is cheaper to immediately buy a new locking device. But this concerns mostly the deadbolts of domestic production. If in your metal door there is an expensive imported bolt model, under which the whole door construction was constructed, it is sometimes impossible to insert another lock.

We have to either change the door entirely, or still try to repair the locks of metal doorframes. Of course, if you do not have experience in such matters, and you are not familiar with the design of the deadbolt, you will need a good specialist.

When is it possible to repair the castle

With some problems in the work bolt can cope on their own.

So:

• If the door does not slam shutit may not even be in the lock, but that the tongue does not get into the mating part of the door frame due to the skew of the door unit (see Repair of entrance doors).
• If the lock is closed only with a strong push on the door, it needs to be adjusted, or to bore receiving holes for crossbars.
• If the lock does not work well with both the closed and the door open, it will have to be disassembled to find out the cause of the jamming, to detect the failed element and replace it.
• If the key is badly inserted into the cylinder bolt, you can replace the dead bolt bolt. But do not rush to immediately repair the locks for metal doors - repairs may not be necessary. It may be enough to clean and lubricate.
• If the same happens with the lever lock, you need to adjust the pad. If this does not help, your keys may be worn out. In this case, you will have to replace constipation.

Practical tips on repairing locks

The self repair options offered below are applicable only for ordinary lever or cylinder locks.

In the case of more complex mechanisms without a master and special tools will not do:

1. Check how the bolt works when the door is open. If the key is easily inserted and turned, setting the crossbars in motion, then it’s not the lock, but the counterpart. It should be squandered, and the lock will function normally.
2. If the constipation refuses to work even with the door open, remove the cylinder mechanism from it and check its operation. If the reason is in it, the repair of the deadbolt in the metal door will only consist in replacing the larva. If the cylinder works, then you need to change the body of the constipation itself or the entire constipation.
3. If the lever does not work, remove it from the door and carefully remove the cover by unscrewing the screws securing the housing halves. Carefully inspect the mechanism to understand what exactly interferes with the normal operation of constipation. If you find that the cause is a broken spring, do not try to replace it - it is better to buy a new constipation.

Attention! When disassembling the bolt, be careful and careful. And if you are not familiar with the principles of its work, it is better not to try to repair it yourself. Improper actions can lead to the final breakdown of the mechanism that a specialist could adjust in a matter of minutes.

Causes and Effects

If constipation began to work poorly, do not immediately rush to change constipation. Very often the reason for this is the elementary clogging of the keyhole.

This can happen by itself over time, but quite often the hooligans, hanging into the holes for the keys of matches or pouring glue, become the culprits. In this case, it is enough to clean and lubricate the deadbolt well in order to return it to work.

Unfortunately, there are also such situations as an attempt by the attackers to break the lock or a forced emergency break in the event of an emergency, when there is simply no time to wait for owners with keys (fire, leakage, etc.).

After this, repair of metal doors of locks is possible only if it is enough to replace the damaged structural part. But more often it is much easier to change the constipation entirely.

If you can not open the metal door with a complex safe bolt, immediately call a specialist. It is unlikely that you will be able to find the necessary tools and units to open the door without affecting the constipation (see How to open the door without a key).
