How to Tell If Someone Has Tried to Pick or Tamper with Your Lock

Have you ever come home and felt like something was… off? Maybe your key didn’t turn as smoothly, or the lock looked slightly scratched. If you’re wondering whether someone’s tried to pick, bump, or tamper with your lock, there are definite signs to watch for.

At Affordable Security Locksmith And Alarm, we help Phoenix homeowners identify break-in attempts—even the ones that fail. Here’s how to spot lock tampering and what to do if you suspect it’s happened.

Common Signs of Lock Tampering

Visible scratches around the keyhole
Look for fine, circular scratch marks—especially if they weren’t there before. Lock picks, bump keys, or screwdrivers can leave subtle damage.

Loose or wiggling lock hardware
If your deadbolt or knob feels loose, crooked, or unstable, it may have been forced or pried. Tampering often involves pressure that distorts or weakens the lock housing.

Key suddenly doesn’t turn smoothly
If your key goes in but feels tight or catches, it could be a sign someone’s inserted a foreign object into the cylinder.

Lock suddenly doesn’t work
If your lock is jammed, completely unresponsive, or your key no longer fits at all, someone may have damaged it trying to force their way in.

Unusual marks or chips on the door frame
Attempted break-ins sometimes leave pry marks or splintered wood around the frame—even if the person didn’t get inside.

Missing screws or hardware
Check for loosened or missing strike plate screws, especially if they were secure previously.

Signs your door was open or partially unlocked
If your door was found ajar or you notice things moved slightly out of place, that could be a sign someone got in—or almost did.

What to Do If You Suspect Lock Tampering

Don’t ignore it
Even if they didn’t get in, someone trying to access your home is a serious concern. Ignoring the signs could lead to a second, more successful attempt.

Take photos
Document scratches, hardware damage, or anything that looks suspicious—especially before fixing or changing the lock.

Call a locksmith
We’ll inspect the lock, check for damage, and either rekey or replace it depending on what we find. We can also reinforce the strike plate and door frame for added protection.

Consider upgrading
If someone tried to pick your basic lock, it may be time to switch to a bump-proof, pick-resistant, or high-security lock system.

Alert your neighbors or HOA
If you live in a community or multi-family unit, share the info so others stay alert. Tampering isn’t always isolated.

Report to local law enforcement if needed
Especially if you notice repeat signs or your neighbors have seen suspicious activity in the area.
