Why Can’t The Cross Key Be Inserted

Safety locks solve all “lock” things for you. “Lock” problems can always find the answer here. For example, some people asked if it is still good to lock the door when you go out in the morning, but after the meeting, why can’t the cross key be inserted?

Safety locks believe that there are three possibilities for this situation:

1. You did not return to the position when you pulled out the key, causing the keyhole to be misplaced (most of the keys are overmatched, the number of times of matching is too many, and the matching is smaller than the original, resulting in the keyhole being smaller than the original space It is bigger, so it is possible to pull out the key in any direction).

2. The safety lock itself has quality problems.

3. The lock was opened by a thief with a tool.

This is the reason why the cross key cannot be inserted.
