Key Snapped in Lock? South London Emergency Locksmith
When a key breaks off inside a lock, the fragment can jam the barrel completely — leaving you locked out. We use specialist extraction tools to remove broken key fragments without drilling in most cases, usually in under 20 minutes.

Don't Panic — We Extract Broken Keys Without Drilling
Keys snap for a reason — and it's rarely random. Metal fatigue builds up over years of daily use, wearing the key thinner at the bow or blade until one firm twist snaps it clean. Forcing a stiff or jammed lock is another common trigger: the lock resists, you push harder, and the key gives way before the lock does. Cold weather tightens tolerances inside the cylinder. Poorly cut duplicates flex under load in ways the original never would. By the time a key snaps, the lock has usually been sending signals for a while — stiffness, scraping, resistance at the turn.
Tweezers grip the visible edge of the fragment and push it deeper into the barrel. Superglue bonds to internal lock components. WD-40 lubricates the barrel walls, making the fragment harder to grip with extraction tools. Any of these turns a straightforward extraction into a lock replacement job. Call us first.
Our extraction process starts with a non-destructive approach every time. We use purpose-made broken key extractor hooks — thin steel tools designed to catch the key's serrations and draw it straight out without damaging the cylinder. The whole thing takes under 20 minutes in most cases. Once the fragment is out, we check the lock's turning mechanism and advise on whether it needs servicing or replacement. If you need a new cylinder, we carry stock and can fit it on the same visit. For information on lock types, see our lock types guide.
Common Reasons Keys Snap in Locks
Metal Fatigue
Years of daily use thin the key at stress points — usually the shoulder or blade. One day the accumulated wear reaches the point of failure.
Forcing a Stiff or Jammed Lock
When a lock is sticky or resistant, the instinct is to push harder. The key takes the stress before the lock does — and snaps.
Cheap or Poorly Cut Duplicate
Poor quality duplicates have inconsistent cuts that flex unevenly inside the cylinder. Under load, they bend and snap where the original key never would.
Cold Weather
Metal contracts in low temperatures, tightening the tolerances inside the cylinder. A key that works fine in summer can bind and snap on a cold January morning.
Worn Lock Internals
Locks wear from the inside out. Worn pins and springs create uneven resistance as the barrel turns, putting twisting stress on the key at the wrong moment.
Twisting Under Pressure
Rushing — carrying shopping, cold hands, late at night — means more force and less precision. A key turned sharply at the wrong angle catches and snaps.

What To Do While You Wait
Don't Try to Extract It Yourself
Tweezers are the most common mistake. They grip the edge of the fragment and push it deeper into the barrel — making professional extraction harder or impossible.
Avoid Superglue and WD-40
Superglue bonds to internal lock components permanently. WD-40 lubricates the barrel walls, making the fragment harder to grip with extraction tools. Leave both alone.
Don't Turn the Lock
If any key section remains outside the barrel, turning the lock drives the fragment further in. Leave the lock exactly as it is until we arrive.
What Our Customers Say
"Key snapped in my front door at 9pm on a Tuesday. Called, got a price immediately — no nonsense. Locksmith was here in 25 minutes, had the fragment out in under 10. Didn't need a new lock. Total relief."
David R.
"I'd already tried tweezers before calling — probably made it worse. They were honest about it, still got it out without drilling. Replaced the cylinder as well. The whole thing was done and dusted within the hour."
Priya N.
"Broken key in my back door on a Sunday morning. Marcus answered immediately, gave me a fixed price, arrived when he said. Key extraction took about 15 minutes. Wouldn't hesitate to call again."
