Snapped Keys
One second the key is turning, the next you're holding half of it while the rest sits inside the lock. A snapped key is a nasty surprise, and pushing at what's left only drives it deeper. Knightsbridge Locksmiths extracts snapped keys across Knightsbridge and London, drawing the broken piece out cleanly and getting a fresh, sound key into your hand in its place.
Why Keys Snap
Keys don't usually break out of nowhere — a bit of force, a cold morning or a worn key is often behind it. Knowing what caused yours helps us stop it recurring, not just remove the piece.
Forced in a Stiff Lock
A lock that's begun to stick tempts a hard turn, and that's the moment a key shears. We free the mechanism as well as extracting the broken part.
Cold-Morning Breaks
Frost stiffens a lock overnight, so a key that turned fine all summer meets far more resistance and gives way. We ease the lock and replace the key.
Thin, Worn or Copied Keys
Years of use, or a poor duplicate, leaves a key weak at the shoulder. Once it fails, we make a fresh key to the lock so the weak one is retired.
One Team to Extract It and Replace It
The broken piece out, a fresh key made, and the stiff lock behind it eased — the same engineer handles all three, priced before we travel and itemised on the invoice after.
Drawn Out Clean, Not Forced Deeper
The wrong approach turns a snapped key into a scrapped cylinder. We use proper extraction tools that grip the broken piece and pull it free without scoring the barrel, then make a fresh key and check what caused the break.
Purpose-made extractors
Tools designed to hook the broken piece and draw it out, rather than shove it further in.
Cylinder saved where we can
A clean extraction usually spares the lock, so a snapped key rarely means a new one.
A fresh key on the spot
A working key made from the lock once the piece is out, so you're not left stranded.
The root cause dealt with
A stiff or worn mechanism serviced, so the replacement key doesn't go the same way.

On site we draw the broken piece out with the right tools, sparing the cylinder.

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.
Snapped Keys Knightsbridge (SW7)
Front-door keys around Belgrave Mews West snap when a stiffening lock meets one hard turn too many. We draw the piece out, then ease the lock so the fresh key turns without a fight.
Snapped Keys Chelsea & Belgravia (SW3 / SW1X)
Shop and office keys off Gertrude Street snap mid-shift and leave staff shut out of a working unit. We prioritise those, remove the piece and make a fresh key so the day carries on.
Snapped Keys South Kensington (SW7)
Communal keys around Queen's Gate Terrace snap in stiff, heavily used entrance locks. Extracting the piece and servicing the lock stops the next resident's key breaking too.
Snapped Keys Pimlico & Belgravia (SW1P / SW1E)
Back-door keys around Warwick Way snap most often on frosty mornings, when the lock has stiffened overnight. We remove the broken key and free the mechanism so it turns cleanly again.
Where We Extract Snapped Keys
Based at 4 Montpelier Street in SW7, we extract 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 — 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 a snapped key mean a whole new lock?
Rarely. A clean extraction usually leaves the cylinder intact, so you just need the broken piece out and a fresh key made.
Why do keys snap in the first place?
Usually a worn key meeting a stiff lock, or too much force on a key that's turning hard. Easing the lock and retiring the old key stops it recurring.
Should I try to pull the broken piece out myself?
Better not — home attempts tend to push it deeper or damage the barrel. Leaving it for proper tools keeps the lock intact.
Can you make a new key from just the half I'm holding?
Often the fresh key is made from the lock itself once the broken piece is out, so a missing half is rarely a problem.
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.
