The lock is an integral element of everyday life, which sometimes brings its owner and raises the question: how to open the door if the lock is jammed?
There are many reasons why locks of the entrance or interior doors can be damaged, respectively, there are various ways to solve the problem.
Therefore, before you start to open the jammed lock, you need to find out the true cause of the defect.
Causes of defects
Unfortunately, perfect locks have not been created yet, which would work without problems. Any locks can break: code and mechanical.
A locking mechanism may be broken at the entrance or interior doors, but the causes of the damage are generally the same.
Like any mechanism, the lock warns its owner about the occurrence of the problem. In one day, the lock can jam, and the next - it stops turning completely.
Therefore, even with a slight difficulty in opening or closing the lock, you should think about changing the locking mechanism, as tightening the problem will lead to a waste of money for qualified professionals.
So, let's consider the possible causes of damage to the lock of the entrance and interior doors:
- opening the mechanism by manipulation, i.e.without a key, with various tools;
- finding in the borehole elements of a foreign character: a fragment of an old key, garbage, etc.;
- clogging a hole with dust or metal shavings when installing a cylindrical model;
- no regular lubrication or rinsing;
- blown door due to high humidity;
- application of the key not only for the purpose of opening and closing the mechanism, but also for other purposes, for example, for opening bottles, etc.;
- sloppy use of metal and wooden doors( strong slamming);
- excessive force during use of the door and lock;
- a crookedly installed door;
- use of a low-quality key made as a duplicate;
- locking the sting and dropping the pin out of the lock;
- factory marriage;
- a strong keystroke if the lock is a code lock.
The most common causes of lock jamming are presented, and all of them depend on the nature of the operation, except factory rejection.
What should I do if the lock is jammed?
The jamming of the lock catches at the most inopportune moment, so you need to know: what measures to take if the castle is stuck? The main condition for opening a jammed lock is accuracy.
Do not use excessive force: if the lock breaks and does not open, an excessive load will only complicate the situation.
In the event of damage, the order of the operation depends on the type of lock: lever, cylindrical, code.
If the cylinder( larval) mechanism is broken, then the following can happen:
- it is impossible to pull out the key;
- the problem of turning the lock;
- scripting when opening and closing.
In cases where the larva of the mechanism has jammed or the key is stuck, only an experienced technician can open the mechanism without damaging the lock and the door.
If it is possible to open the door only on its own, then it is necessary to proceed as follows: first, the key and door slots are cleaned with a rough brush, thereby eliminating dust or metal shavings that could cause the defect.
After this, the mechanism must be smeared with automotive oil, WD-40 or kerosene, and then try to turn the key. The process is presented in detail on the video.

If nothing has helped, and the lock is still jammed, and the key is not pulled out, you can try to pull out the key with pliers.
If this does not work out, then it is necessary to drill out the larva and put a new one.
You should also pay attention to the door: it should not be swollen and skewed, the hinges should not be damaged.
To correct these phenomena you will need a wedge or chisel, you can use a thick screwdriver. The selected tool must be driven in the place of placing the door on the box.
When the tool is slightly pounded into the slot, it is necessary to try to put the door in place using the tool as a lever. At the same time, you need to pull the door by the handle, trying to open it.
There may be a situation where the door is not locked, but does not open due to the fact that there was a problem with the latch-latch.
If the spring has been damaged, the latch fits snugly into the door. To release, simply press the latch.
To fix this problem, you will need to find a flat object: a metal ruler, a steel knife or a conventional plastic card.
The plastic card is inserted into the slot between the door and the box at the location of the latch. Then, the card should be tilted towards the door handle and press on it, at that moment it should feel sliding on the sloping cut of the tongue.

Then you need to press the flat object in the opposite direction from yourself so that the latch leaves in the mechanism. In this case, you need to pull the door, trying to open it.
If you need to open the lock on the side where there is no cut, then the card is inserted from the top, obliquely.
If the lock of the door lock is jammed, and it is not possible to make revolutions, it is recommended to cut the longitudinal protrusions preventing the key from coming in.
After this, try to insert the key with the other side.
If it is not possible to cut off the protrusions, then the keyhole needs to be pressed slightly and the key is inserted with the other side.
If there is a key jam in the mechanism of this type, first it is necessary to lubricate the lock with silicone, it is better to choose in the form of a spray, then gently pull out the key with gently smooth movements.
If everything turned out, then in order to avoid a similar situation it is necessary to replace the lock or its larva.
If the mechanism is seized exactly when closing the door, then you need to baste the doorframe with a file.
If the code lock of the entrance door is broken, then, most likely, it will be necessary to reprogram.
Since the key lock does not open with a key, it does not have a well, which excludes the causes of breakdown that appear in mechanical locks.
If the code lock can not be opened due to the keystroke, you can try to pick up a key with some sharp object and try to pull it out.
If this does not work, then, most likely, you need to turn to the help of specialists.
Also, some doors are equipped with a handle with a latch, representing a key located on the cover from the inside.

If the door is accidentally closed, then a long, flat object will need to be inserted into the hole under the handle and turn. After this, the latch will turn and re-engage.
If all the possible options are applied, and the door is still locked, then you can proceed to radical measures - knocking out the door. For this, a towel is applied to the shoulder.
Then you need to press the shoulder on the door in the area of the edge of the opening. It will be better if the legs are in anything to rest against, and a free hand you need to hold on to the wall.
Thus, if the lock on the iron entrance or interior door has broken, you first need to understand the reason, after which you can proceed to solve the problem on your own.
If this is not possible, then it is recommended not to aggravate the situation, but to call qualified specialists.
