What to Do When a Key Breaks in a Lock

START WITH THESE STEPS

Avoid making the problem worse and prepare the right information

1. Keep the other half of the broken key
2. Note whether the lock was turning when it broke
3. Do not force sharp tools into the keyway
4. Identify whether it is a home, vehicle, or commercial lock

Why an initial assessment matters

The same visible symptom can come from a key, cylinder, door frame, vehicle immobilizer, or electronic component. Clear information reduces unnecessary attempts and helps prepare the correct tools and parts.

When to stop trying it yourself

Stop if a key begins to bend, the lock makes unusual sounds, the frame is under visible strain, the vehicle shows an immobilizer warning, or a safe enters lockout mode. Record the current condition instead.
