The key in the lock broke, how to remove the chip and open the door?

With either of us, it may happen that when closing or opening the apartment door, the house or the garage, the key in the lock broke. How to pull out the piece left in the lock and open the door. If you do not panic and approach the issue calmly and competently, in 80% of cases you can cope with the problem without losses, and in 10% - you will be able to confine yourself to replacing the larva or castle.

The main reasons why the key in the lock

breaks. There are quite a few reasons, but the main ones are as follows:

• Wear of the internal lock mechanism and the key itself.
• Pollution of a secret mechanism or entry of foreign objects into the well.
• Error opening the lock( not fully inserted key or mistakenly inserted another).
• An attempt was made to rotate the jammed key with help of improvised objects and tools( pliers, hammer, steel pin, etc.).
• Poor-quality material, from which the lock is made.

But whatever the reason, if the key broke and the chip remained in the lock, it is necessary to decide what to do in this situation.

How to remove the key chip from the keyhole

If the key in the lock breaks, do not immediately resort to radical measures - to break open the door or cut it with a bulgarian. We must try to remove the chip and open the door.

In no case should you immediately throw away a piece of the key left in your hands. If you can remove the jammed part, then in two halves, the specialists in the workshop will make a new key in a few minutes, which can be used to open the lock.

Before taking any action to remove the jammed part of the key, it is necessary several times to drip the keyhole into the keyhole and wait 15-20 minutes for it to spread all over the surface of the wreck and the lock mechanism. This will greatly increase the chances of success. For lubrication, WD-40, gun and engine oil( spindle), any transmission or automotive oil, and brake fluid are suitable.

• The ideal and easiest way to get a broken key is to disassemble the lock and get the chip. But this can be done when the door is open( or it is possible to open it from the inside).If you plan to use the lock in the future, then before assembling it should be well cleaned and lubricated.
• In case a piece of key is sticking out of the hole, you can try to grab it with round-nosed pliers, small pliers or tweezers. Do this carefully. Do not put a lot of force or jerk. Gently rocking up and down and from side to side, you have to try to pull out the jammed part. You can simultaneously tap lightly on any accessible part of the castle. Vibration and shaking will help move the fragment from its place.
• If possible, slip two thin silas between the wreck and the keyhole from the top and bottom( or sides) and slip the jammed part out to try to extract it.

• A truly jeweler, but very effective way of extracting a wreck of any key - using a self-tapping screw. At the end of the wreck it is necessary to drill a thin hole, while trying not to damage the lock and break the drill. In the resulting hole, it is necessary to screw the self-tapping screw of the corresponding diameter. Then, holding on to the hat of the samoreza, constantly shaking the jammed piece, gently "fetch" it from the lock.
• Less effective, but quite effective way - with a saw from a jig saw. It is necessary to cut off the fixing tip at the saw. The saw must be pushed under the key in such a way that the incline of the denticles is "on itself", gently rotate the teeth in the direction of the wreckage and pull out. The operation is repeated several times until it is possible to remove the jammed chip.

• If the key is made in the form of a cylindrical pin with barbs( lock locks), then it is possible to get the chip with a copper or brass tube of suitable diameter. Its size is selected by the remaining part of the hands. The tube should be put on the pin with a very high force. Slightly widening the very tip of the tube, it is necessary to heat it with a blowtorch or over a gas burner, then with effort put on the piece sticking out in the lock. Waiting for the tube to cool well, pull it out of the lock with the clipped part of the key.

Open the door with the lock damage

What to do if the key in the lock breaks and you can not remove the chip. To open the door, you have to sacrifice, at best - the larva of the castle, at worst - by the castle itself.

To open the lock, you can proceed as follows:

1. If the lock is not properly installed, the cylinder mechanism can protrude above the cover plate. In this case, the cylinder end can be clamped with a gas key and folded. It remains to clear the hole from the debris and open the door with a flat-blade screwdriver.
2. If the cylinder does not protrude, then you can additionally sacrifice the overlay, tearing it with a nail or chisel, after which you can use a gas key.
3. In the absence of a gas wrench, it is possible to knock out the cylinder with a hammer, but it is advisable to do this after the internal armored plate is removed, which is not always possible. It must be borne in mind that after such an opening, the lock will most likely have to be replaced.
4. With the help of a drill, you can drill a cylindrical insert slightly below the key hole. This will destroy the tsugali - the mechanism of the code. Then, pulling out the drill, gently tap the end of the cylinder so that the debris falls down and does not jam the lock. It remains to insert a flat screwdriver instead of the key and open the lock. If the key is bilateral( it has figured notches on both sides), it is necessary to drill from two sides.
5. You can completely drill the cylinder mechanism. A drill with a diameter of 6-10 mm is used for this. The cam is usually damaged. To unlock the lock, you need to bend the end of the screwdriver or strong wire about 1 cm( it should get the locking mechanism), insert it into the hole and push the bolt.

If you can not cope with the problem yourself, it's still not worth breaking or cutting the door. It is better to contact the customer service, whose employees know what to do in a particular situation.

The reason for the breakage of the key is often a contamination or wear of the lock. Extend its performance can be, periodically lubricating the mechanism with spindle or gear oil. If the lock began to seize periodically, it is better to repair it or replace it.
