A broken key stuck in a lock is a common problem, especially with older or worn keys and locks. Do not try to force the broken piece out with pliers or push it further in with another key — this can damage the lock pins and make extraction much harder. A locksmith can extract the broken key fragment, test the lock, and cut a new key, usually within 15–30 minutes on-site.
What to do right now
- 1
Do not push the key further in
If part of the key is protruding, do not try to turn it or push it deeper. Do not insert another key or any tool into the keyhole. This can push the broken fragment past the pins and make extraction much more difficult — or damage the lock entirely.

Try gentle extraction if the key is protruding
If a portion of the key is sticking out, you can try gripping it with thin needle-nose pliers and pulling it straight out. Apply a tiny drop of lubricant (WD-40 or similar) around the keyhole first. Pull gently and steadily — do not twist or jerk.

Secure your property if possible
If you cannot lock the door, stay with the property or ask a neighbour to keep watch. If the broken key is in a deadbolt but you have a separate handle lock that still works, engage that as a temporary measure.

Call an emergency locksmith
A locksmith will use specialist extraction tools to remove the broken key fragment without damaging the lock. They can then test the lock mechanism and cut a new key from the broken pieces or from the lock code. If the lock is damaged, they can replace it on the spot.
When to call an emergency locksmith
- ⚠️The broken key fragment is fully inside the lock and you cannot grip it
- ⚠️You have tried extraction yourself and the key will not come out
- ⚠️The lock mechanism appears damaged after the key broke
- ⚠️You cannot secure your property because the lock is inoperable
- ⚠️The key broke in the ignition of your car
- ⚠️You need a new key cut urgently and do not have a spare
