Use a pencil to draw on the deadbolt, or use oil (do not use cooking oil) to lubricate, if it is ineffective, you must remove the internal oil or replace the lock body.
Start with two aspects to solve the problem, one is if it is rusty because of lack of oil, put on some sewing engine oil or car engine oil. The second is to remove it and check the deadbolt spring, it may be broken or dislocated, and you can deal with it.
If you can, you can raise the indoor temperature and you can avoid it. The simple way is to lubricate the lock cylinder with pencil foam. If you really can't open it. >>>More
Then use a flat chisel to directly hit the connecting rod, if the deadbolt is dragged out, in the case of the connecting rod can be seen in the gap of the door, then this gap will increase in this case, you first need to judge what is the problem, if it is really a problem with the deadbolt, you can judge it in combination with the situation after you usually close the door, so as not to pry the appearance of the door yourself, if the deadbolt runs over, according to the conventional judgment, you can open the door after breaking, and there is a simple way, you can first use the airbag to support the gap of the door, If there is no problem with the deadbolt, there is no gap or only a little gap when the handle is pulled after closing the door, and you need to find someone from the lock picking company to solve it.
