Why keys break

Keys rarely snap without a cause. Common ones are a key worn thin or cracked at the shoulder, a key that is a poor copy of the original, or a lock that has become stiff so that more and more force is needed to turn it. If the lock itself was the cause, simply removing the broken piece isn't enough. The stiffness needs dealing with too, or the next key will go the same way.

What not to do

Don't push the remaining part of the key, or another key, into the lock. It can drive the broken piece deeper.
Don't use superglue to bond the pieces. Glue can set inside the mechanism and ruin it.
Don't dig at it with pins or knives. This can damage the internal parts and make extraction harder.
Don't spray lubricant in to "help it slide out". It can carry dirt further into the lock.

If part of the key is sticking out and comes away with a gentle, straight pull, that's fine. Otherwise leave it. Our article on a broken key in a lock explains why.

What happens on site

The technician removes the broken piece with suitable extraction tools, then tests the lock with a working key. If the lock is undamaged and turns freely, that may be all that's needed. If it was stiff, worn or damaged by earlier attempts, you'll be told whether a repair or a replacement is sensible, and what each would cost.

Keep the broken pieces

Keep both halves of the key once they're out. Seeing where and how it snapped helps show whether the key or the lock was at fault. We don't cut replacement keys. If the remaining key is the last one and is worn, discuss with the technician whether the lock should be replaced while it still works.

Questions customers ask

Will the lock have to be replaced?

Not necessarily. Many locks work normally once the broken piece is out. Replacement only comes up if the lock is damaged or worn.

The key broke with the door locked — can you still get me in?

Usually the broken piece is extracted first and the lock then operated normally. If that isn't possible, the technician will explain the alternatives before doing anything destructive. See also emergency lockout help.
