How to Know If Your Lock Has Been Tampered With in Phoenix

You come home and something feels… off. Maybe your key is harder to turn. Maybe your door isn’t shutting quite right. It’s possible you’re just imagining things—or someone tried to tamper with your lock.

At Affordable Security Locksmith And Alarm, we help Phoenix homeowners detect signs of forced entry or tampering. Whether it’s a break-in attempt or someone trying to test access, here’s what to look for and how to respond.

If something doesn’t feel right, schedule a lock inspection here.

Common Signs That a Lock Has Been Tampered With

Visible scratches or tool marks
Look for fresh scratches around the keyhole, doorknob, or strike plate. If you see marks that weren’t there before—especially circular ones near the lock—it could be a sign of a lock pick or screwdriver.

Loose or damaged lock hardware
If your deadbolt or handle feels wobbly, looks bent, or doesn’t sit flush with the door anymore, it may have been forced or tampered with.

The lock feels “off”
If your key suddenly stops turning smoothly or the lock resists when you turn it, something may have shifted inside—either from force or a tool.

Misaligned door or frame
Break-in attempts often involve kicking or prying. If your door looks crooked or the frame is cracked, someone may have tried to force their way in.

Unexpected key behavior
If your key sticks, doesn’t go in all the way, or suddenly doesn’t work, the internal pins or cylinder may have been manipulated or damaged.

Security cameras show unusual activity
If you have a video doorbell or security system, check footage for anyone loitering or touching the lock.

What Tools Do People Use to Tamper With Locks?

Common tools include:

Lock picks or bump keys
Used to open locks quietly without visible damage.

Screwdrivers
Used to pry or force open poorly secured deadbolts or door frames.

Credit cards or plastic shims
Often used on spring latch locks—not deadbolts—to slip the door open.

Drills
Used to break into locks quickly, but they leave obvious damage.

What to Do If You Suspect Tampering

Don’t use the lock until it’s inspected
If something feels off, avoid turning the key repeatedly—it could break or worsen the damage.

Take photos of any visible damage
You may need them for a police report or insurance claim.

Call a local locksmith for inspection
We’ll check for internal damage, test your hardware, and let you know if the lock needs repair, rekeying, or replacement.

Consider rekeying or upgrading your locks
Even if the lock wasn’t breached, the attempt alone is reason enough to change your keys—or upgrade to a more secure lock.

Report suspicious activity to your HOA or local police
It could help identify a pattern of neighborhood break-in attempts.
