A lock that has snapped off — where the lock body, cylinder, or handle has physically broken away from the door — is a serious security issue that needs immediate attention. This can happen due to force (attempted break-in), metal fatigue, extreme age, or a manufacturing defect. Do not attempt a temporary fix with tape or glue. Call an emergency locksmith who can replace the lock and restore your security, typically within 30–45 minutes.
What to do right now
- 1
Assess the damage
Determine what has broken: the lock cylinder, the handle, the deadbolt housing, or the entire lock set. Check if the door can still be closed and held shut even if it cannot be locked. Check for signs that the damage was caused by a break-in attempt.
- 2
Secure the door temporarily
If the door still closes, prop a heavy piece of furniture against it from inside. If you have a chain lock or slide bolt on the inside, engage those. If the damage leaves a gap or hole, do not leave the property unattended.
- 3
Check for break-in signs
If the lock was forced or appears to have been tampered with, call police on 131 444 to report it. Check for tool marks, scratches, or damage around the lock area. Take photos for insurance purposes.

Call an emergency locksmith
A locksmith can replace the broken lock with a new one, usually from stock carried in their van. They can fit a like-for-like replacement or upgrade you to a more secure lock. Ask about deadbolts and high-security options while they are there.
