Anonymous users2024-01-24Under normal circumstances, the door lock can not be retracted, it is estimated that it should be the deadbolt, there are two possibilities, one is that the lock body is broken, and the transmission mechanism cannot drive the deadbolt to rebound, so it is OK to replace the lock body. The other is the problem of the lock cylinder, the cam (fork) of the lock body cannot be driven by the lock cylinder, resulting in the failure of the deadbolt to rebound. This is usually due to the damage to the internal structure of the pin or the lock cylinder, and the lock cylinder needs to be replaced.
How to identify: first in the case of not dismantling the lock, in the state of the door open, twist the lock cylinder with the key to see if it is smooth, if it is, but the deadbolt still does not rebound, the heart is basically judged to be the problem of the lock body, if the key does not twist, you need to dismantle the lock cylinder as shown in the following figure, test the lock cylinder separately, first to see whether the fork is damaged, and then to see whether it can be twisted, if not, then it is the lock cylinder problem, if it can, it is still the lock body problem.

Anonymous users2024-01-21Will it be a problem with the lock cylinder, you can ask Li Wen to lock the city.
Your security door is outside, lift the lock handle up, and you'll be fully safe.
The lock cylinder is broken! It is recommended to take a few more keys and try to add some vegetable oil to the lock cylinder, but only to change the lock cylinder.
Don't be able to lubricate the oil, because the lubricating oil is easy to get dust on the key, and it is easy to get into the lock cylinder if you open the door again. It is best to grind with a pencil or have soap. If you still can't open it, you can only find a lock picking company.
The fastest way is to reset the pins, if you can't reset them, drill the lock cylinder with an electric drill, take out all the pins and then unscrew the lock cylinder to replace it.
It's right to get some pencil powder, but if the pencil powder has tiny particles that affect the insertion, try to drip a little oil. >>>More
