How can you tell if a lock has been tampered with?
Your home or business security could be compromised without your knowledge. Knowing how to detect in time if someone has tried to force open your lock can prevent burglaries and further vulnerabilities. Although sophisticated techniques may go unnoticed, there are several signs that can alert you to an attempted unauthorized entry.
1. Visible signs on the lock

– Scratches or abrasions from tools or picklocks near the cylinder or around the lock area. These marks may be small, but they are noticeable and weren’t there before.
– Dents or deformations may be caused by impacts or pressure from tools and can leave imprints on the metal or the surrounding surface.
2. Changes in operation

– The key is difficult to insert, or it doesn’t turn smoothly. This could indicate internal damage caused by an attempted forced entry.
– The cylinder is loose or unstable: if the lock feels loose or wobbly, it’s likely that someone tried to remove or force the cylinder.
– Obstruction or jamming: if the key gets stuck or suddenly doesn’t fit properly, there may be an obstruction or internal damage.
3. Metal shavings or foreign materials
Small fragments or plastic pieces, on the floor near the entrance, can indicate an attempt to tamper with the lock using tools or techniques such as lock bumping. Metal shavings or dust result from drilling into the lock, forced wear of the cylinder, or internal damage to components. These traces are usually found on the door threshold or doormat.

4. Signs of liquids or foreign substances
If you see any residue around the lock, such as:
– Silicone or glue, which indicates an attempt to jam the lock.
– Graphite or excessive lubricant could indicate sabotage before a burglary.
– Burn marks from using power tools to force the door open.
5. Other signs to consider
– Changes in the door’s alignment or difficulty closing. An attempted break-in can damage the locks and internal mechanisms.
– Damage or marks on the door frame, such as pry marks, screwdriver marks, or other tool marks, suggest an attempted forced entry.
– Strange noises or creaking sounds coming from the lock mechanism.

If you notice any of these signs, act quickly!
1. Don’t ignore the signs: inspect the lock and door carefully.
2. Contact a professional locksmith: an expert can assess the damage, detect any tampering, and recommend repairs or replacements.
3. Strengthen your security. Consider installing anti-bump locks, high-security cylinders, or electronic security systems.
4. Report it to the authorities if necessary, especially if there are signs of attempted theft or burglary.
