EMERGENCY OPENING OF A DOOR: WE DRILL A LOCK INSERT

Send

This is the most common method of opening doors with mortise locks with inserts if you have lost the key. This method is used by special organizations providing relevant services. Emergency services usually knock the door immediately, as human life is in danger. But if nothing is threatening anyone and you want to open the door with minimal damage, then this instruction is for you.

Theory

Mortise door lock has a housing and a removable insert, called in common people - the larva. Part of the insert just sticks out of the door and keys are inserted into it.

This insert contains a special code mechanism with pins and springs, which allows or does not allow the cylinder to rotate. Bottom rivets are visible in which the code pins are located.

We need to drill this mechanism with a drill or screwdriver.

Open the lock with a keyless insert

Let's move on to practice. Kernim point for drilling. It is better to make a hole immediately below the cylinder, since under it immediately there are locking and code pins.
Well, if there is no core, then this can be done with the same drill.

The point is done. Now, at the beginning of drilling, the drill will not run from side to side.

We begin to drill. The drill can be taken in a diameter of 4-8 mm.

It is drilled quite well. The main thing is to keep the drill level so that the hole goes straight in depth.

Drilled. Depth depends on the larva.

In general, you need to stop periodically and look through the hole to see if the holes for the code pins have ended, because behind them is solid metal.

The line of holes is visible below:

And on top:

Now you need to hit the insert a couple of times with a hammer with a little effort so that the segments of the pins fall into the drilled hole and do not interfere with the rotation of the cylinder.

Here are a few, they can be seen:

Well, now we take a flat screwdriver, insert it into the key channel and turn the lock insert cylinder. Usually the turn is carried out two turns.

We try to open the door - everything comes off.

And in the end, I would like to add that you have the right to do such actions only with your locks and doors. Helping someone or opening someone else's door is illegal.
