Anonymous users2024-01-23Judging from your situation, there are two possibilities, the first may be that your lock guard is fixed too tightly, resulting in the key not being able to screw the head, resulting in the lock body can not drive the deadbolt to rebound when rebounding, and the second possibility is that the lock body is a problem, and the mechanical transmission device inside is problematic, resulting in the deadbolt can not rebound.
Solution: The first possibility is to try loosening the screws and test them to see if they work. If it is easy to use, it will be used, and if it is not easy to use, replace the lock cylinder of other sizes: the second possibility: replace the lock body.
