While coming home to an open door is frightening, it usually indicates that the trouble has come and gone. However, if someone tries and fails to force your door lock, they might be planning to return. In this case, understanding the signs of a failed attempt allows you to get replacement locks and prevent future issues. Here are several ways that you can spot issues.

What Are Common Indications of Door Lock Tampering?

1. Damaged Parts

If the trespasser was in a hurry, they may have tried to break open the lock with sheer force. While this often doesn't work, it produces unfamiliar bends and curves in the hardware. If you suspect issues, inspect the latch, knob, and deadbolt of the door for damage. Also, look around the doorframe, as the impact could splinter the wood and leave broken pieces on the ground. You might even notice that turning your key in the door lock is challenging, which is an indication that the internal pins have damage.

2. Marked Paint

Another common tactic is to remove the lock mechanism from the door to get inside the home. However, if you have paint on your door or lock, you can spot this vandalism easily. Often, the loosening and tightening of the lock will leave circular trails in the paint. Alternatively, you may notice small, colored shavings on the ground below the lock.

3. Scratched Surface

If the trespasser tried to manipulate the inner-workings of the door lock with metal tools, they will steal leave evidence. There are two main methods for this: bumping and picking. Bumping requires a trespasser to file a key and hit it against the pins, while picking involves catching the tumblers with a sharp screwdriver or dental pick. These tools often scratch the outside of the lock, revealing shiny nicks in the underlying metal.
