Broken Key Extraction in Brixton
Brixton Locksmith removes snapped keys from door locks across SW2 and SW9, 24 hours a day. The broken piece is extracted with specialist tools, the lock is checked, and a new key is cut. Call or WhatsApp 07984 547185 and do not force the broken piece further in.
A key usually snaps at the worst moment — in a stiff lock, on a cold morning, with the door half open. The broken piece sits inside the cylinder, and the temptation is to dig it out with tweezers. That almost always pushes it deeper.
We extract broken keys with tools made for the job, check whether the lock itself caused the break, and cut you a new key before we leave.

Why do keys snap?
Keys snap for three reasons: the key is worn thin, the lock is stiff, or both. A worn key has less metal at its thinnest point, and a stiff lock asks it to do more work than it can handle. Cold weather makes the metal more brittle, which is why so many keys snap in winter.
Old keys copied from copies are the worst offenders. Each copy loses a little accuracy, and the final key is a rough fit that stresses the blade every time it turns.
How does broken key extraction work?
We use fine extractor tools that grip the broken piece and draw it out along the keyway, without drilling and without damaging the pins inside the cylinder. The lock is then tested with a fresh key to check it turns smoothly.
If the lock itself is stiff or worn, we deal with that too — a lock repair, a new cylinder, or a service — so the next key does not snap the same way. Before you book anyone, the Master Locksmiths Association lists locksmiths by area — worth a look if you have never used a locksmith before.
What should I not do with a broken key?
Do not push anything into the keyway. Tweezers, pins and paperclips push the broken piece deeper and can damage the pins. Do not use glue on the remaining half of the key either — it bonds inside the lock and turns a simple extraction into a lock replacement.
Do not force the door. If the broken piece is stopping the bolt from moving, forcing the handle can bend the mechanism. Leave it, keep the door as it is, and call us.
Getting a new key afterwards
Once the broken piece is out, we can usually cut a new key from the remaining half, or from the lock code if the key is too damaged. If you have a spare, bring it — a fresh copy from a good original lasts far longer than a copy of a copy. If you have lost every key rather than snapped one, our lost keys page explains the next steps.
If the lock caused the break, we recommend dealing with the lock at the same time. A new key in a stiff lock will snap again sooner or later.
Frequently asked questions
Can you remove a key that has snapped in the lock?
Yes, in most cases. We use specialist extractor tools that grip the broken piece and draw it out without drilling or damaging the lock. The lock is then tested with a fresh key. If the piece is pushed very deep, we tell you honestly whether extraction is still possible.
How much does broken key extraction cost?
It depends on how deep the piece is lodged and whether the lock needs work afterwards. Extraction on its own costs less than extraction plus a new cylinder. You get a clear quote on the phone, and we confirm any extra cost before doing further work.
Should I try to remove the broken key myself?
It is best not to. Tweezers and pins usually push the piece deeper, and glue can bond inside the lock and ruin it. Leave the broken piece where it is, do not force the door, and call us. A professional extraction is quick and usually saves the lock.
Can you cut a new key if the old one is broken?
Usually yes. We can cut a new key from the remaining half of the broken key, or from a spare if you have one. If neither is available, we can fit a new lock and cut fresh keys to match. Bring any spare keys you have to the visit.
Why did my key snap in the first place?
The usual causes are a worn key, a stiff lock, or both. Old keys and copies of copies are thinner and weaker than originals. A lock that needs a firm twist puts extra strain on the blade. We check the lock after extraction and tell you whether it needs a service or a replacement.
