Broken key in the lock: step-by-step guide

First reflex: don't force it

Your key broke inside the cylinder and you're tempted to push with the other piece? Don't. Sideways pressure can bend the pins and make the cylinder unrecoverable. In 7 out of 10 cases we see in Brussels, the cylinder is salvageable — if you act calmly.

Extraction methods

1. Fine-tip tweezers

If part of the key sticks out, flat-tip tweezers may be enough. Pull straight, no angle, to avoid bending the pins.

2. Hacksaw blade

Insert the blade with teeth facing the key and hook the piece out. This takes patience.

3. Professional extractor

A locksmith uses a double-hook extractor that slides into the key channel. It's the safest method — the cylinder is saved in 95% of cases.

When to call a professional?

If the piece is deep, the cylinder turns halfway, or you've already tried without success, stop. Each extra attempt risks jamming the pins permanently. Our team responds in 20-30 minutes in Brussels — see our emergency service or call 02 315 91 32.

Preventing breakage

A key rarely breaks by accident. It usually signals a worn or stiff cylinder. If you regularly force it to turn, replace the cylinder before it breaks — far cheaper than an emergency call-out. See our cylinders and locks guide.
