Broken & Snapped Keys
Half the key in your hand and half stuck in the lock is a bad way to start the day — and forcing it only pushes the broken piece deeper. Knightsbridge Locksmiths extracts broken and snapped keys across Knightsbridge and London, saving the cylinder where we can and making you a fresh key on the spot.
Why Keys Snap in the Lock
A key rarely snaps without warning — it has usually been bending or sticking for a while first. Knowing why yours broke helps us stop it happening again, not just pull out the piece.
Snapped in the Cylinder
The most common call: the key shears with half left inside. We extract the broken section without pushing it deeper or scoring the barrel.
Worn, Thinning Key
Old keys wear thin at the shoulder and finally give way. We remove the remnant and make you a fresh key, so the worn one is retired.
A Stiff Lock Did It
A key that snaps often points to a lock that was stiff. We free the mechanism as well, so a fresh key doesn't meet the same resistance.
One Team to Get the Key Out and a New One In
A snapped key, a worn one, or the stiff lock behind it — the same engineer extracts the broken piece, makes you a working key, and frees the mechanism if that caused the break.
Extracted Cleanly, Not Forced
The wrong tool turns a snapped key into a ruined cylinder. We extract the broken piece with proper key-extraction tools that grip it without scoring the barrel, then make a fresh key and check why it snapped in the first place.
Proper extraction tools
Purpose-made extractors that grip the broken piece and draw it out, rather than push it deeper.
Cylinder saved where possible
Most barrels survive a clean extraction, so a snapped key rarely means a new lock.
A fresh key made on site
A working key made from the lock once the broken piece is out, so you're not left stuck.
The cause dealt with
A stiff or worn mechanism serviced too, so the replacement key doesn't snap the same way.
Getting You a Working Key Again
Extraction without damage
The broken piece drawn out cleanly, keeping your cylinder intact wherever we can.

How We Deal With a Snapped Key
- Tell us what happened
Where the key snapped, and whether any part is still sticking out — a photo helps.
- Extracted on site
On arrival we draw the broken piece out with the right tools, sparing the cylinder.
- A fresh key made
A working key made from the lock, so you're back in and turning straight away.
- Cause checked
The lock tested for the stiffness that snapped the key, and serviced if needed, before we finish.
Snapped Key Call-Outs, Neighbourhood by Neighbourhood
Keys give way for different reasons across Central London — here's what our snapped-key call-outs tend to involve in four of the areas we're called to most.
Broken & Snapped Keys Knightsbridge (SW7)
Front-door keys around Grosvenor Place take daily use and eventually shear at the shoulder. We extract the broken half and make a fresh key, then check the lock that wore it down.
Broken & Snapped Keys Chelsea & Belgravia (SW3 / SW1X)
Shop and office keys off Godfrey Street snap mid-shift and lock staff out of a working unit. We prioritise those, extract the piece and get a fresh key made, so trading continues.
Broken & Snapped Keys South Kensington (SW7)
Communal keys around Onslow Crescent often snap in a stiff, well-used entrance lock. Extracting the piece and servicing the mechanism stops the next resident's key going the same way.
Broken & Snapped Keys Pimlico & Belgravia (SW1P / SW1E)
Back-door keys around Warwick Way snap most often in an old uPVC cylinder that has grown stiff. We remove the broken key, ease or swap the cylinder, and hand over a key that turns freely.
Where We Extract Broken & Snapped Keys
Based at 4 Montpelier Street in SW7, we extract broken and snapped keys across Knightsbridge, Belgravia, South Kensington and Chelsea, with wider cover through the SW1 postcodes and central London. A key snapped flush in the barrel or one still poking out, the callout works the same.

FAQs — Broken & Snapped Keys
Can you get a snapped key out of the lock?
Yes, in almost every case. Purpose-made extraction tools grip the broken piece and draw it out without scoring the cylinder or pushing it deeper.
Will I need a new lock if my key snapped inside it?
Rarely. Most cylinders survive a clean extraction, so you usually just need the broken piece out and a fresh key made.
Why did my key snap in the first place?
Usually a worn, thinning key meeting a stiff lock. Servicing the mechanism and retiring the old key stops it recurring.
Can you make a new key if I've only got the broken half?
Absolutely. Once the piece is extracted, a working key can be made from the lock itself, so a missing half is no barrier.
Should I try to pull the key out myself?
Better not — home attempts often push the piece deeper or damage the barrel. Leaving it for proper tools keeps the lock intact.
How fast can you come out?
Same-day visits are usually available from our Knightsbridge base for most SW1, SW3 and SW7 addresses, with snapped keys prioritised.
