Anonymous users2024-01-24Hello, this needs to depend on the specific situation, first of all, to ensure that the key is on this door, there are many people who have more keys or do not have to rely on chaos for a long time! Secondly, look at the problem: is the key not inserted?
Lock cylinder key problem with lead powder to lubricate) inserted into the circle at all? (The problem of the lock cylinder, you need to consider changing the lock cylinder) can be inserted into the circle but can not be opened: less than 2 turns left and right?
A lock is stuck, in this case, knock on the door with your hands or feet to shake the door leaf and turn the key at the same time), can you turn more than 2 times or can't open it? (The oblique deadbolt is stuck and the door is also shaken, and the internal anti-theft is opened (there are two situations in the family that someone at home will let the family open, and there are two situations when the internal anti-theft is opened: the first person generally enters the house from other places and opens the internal anti-theft, and the second lock body has a problem, resulting in the automatic pop-up of the internal anti-theft when the door is locked, this situation is not easy to appear, the probability is very small, but I have seen it).
Maybe the lock is broken.
The details are as follows: 1. The safety bolt of the anti-theft door is removed from the automatic anti-lock (automatic bolt after the door is closed), and the other locks that need to be manually locked will not come out normally. >>>More

It should be that the key rotates 360 degrees back to the original position to take out the key, if it does not return to the original position to take it out, the lock cylinder is easy to break, and it is best to change the lock cylinder if it does not return to the original position.
