Reasons for door lock damage

​In addition to the wear and tear of the door lock itself, loose door hinges, swelling floors, damaged walls, rust or debris near the door may cause damage to the door lock. 

Foreign objects such as hairpins, wires, etc. inserted into the keyhole can also cause damage if done by anyone other than a trained locksmith. 

Therefore, when replacing a new door lock, you should pay attention to the damage near the door. Check the environment to see if the door lock is damaged due to other factors.

Abuse, such as repeated slamming of the door, can contribute to door lock damage, but is most often not the cause. Using a hard instrument such as a hammer or screwdriver will do much damage to the lock, but this kind of abuse is evident.
