Broken Key Extraction in Liverpool
Keys snap at the worst possible moment — usually with the fragment stuck inside and no way to lock or unlock the door. Getting it out cleanly is a specialist job. In most cases the cylinder is completely undamaged afterwards and the same key keeps working. Leave the fragment exactly where it is and call.
The Most Common Causes — and How to Avoid a Repeat
Understanding why keys snap prevents it happening again. The pattern is consistent across most of the callouts we attend.
Worn Key in a Worn Lock
The most common cause. Key and lock wear together over years — the key's cuts round off, the lock's pins loosen. The key sticks more often, more force gets used each time, and eventually the thinnest part of the key — almost always near the shoulder — fails under the cumulative stress. If your key has been stiffening for months, this is the warning.
Replace before it breaks →Cold Weather
Metal becomes more brittle below around 5°C. A key that's been borderline for months will often choose a January morning to snap — the cold that morning being the last straw rather than the only cause. Winter callouts for snapped keys are significantly more common than summer ones.
Emergency cover →Cheap Spare Key Copies
Hardware shop key copies — particularly cheap emergency copies cut from a copy of a copy — are often made from softer alloy blanks than the original. They work initially, then they don't. If you rely on a copy cut from a hardware kiosk for everyday use, this is the likely failure point.
Proper key cutting →Forcing a Stiff UPVC Lock
Lifting the handle on a UPVC door before the door is fully closed against the seal forces the multipoint hooks against the frame. Turning the key in that state puts enormous lateral strain on the key blade — the lock mechanism is fighting against itself and the key is the weakest link. The fix is the gearbox, not a new key.
UPVC lock repairs →Forcing a Sticky Lock
When a lock begins to stick, the instinct is to apply more force. A sticking lock needs servicing or replacing — forcing it with both hands is what converts a £80 UPVC repair into a snapped key inside a cylinder. If turning your key is getting harder, deal with it before it snaps.

What Happens When We Arrive
Assess the Fragment Position
Look at the cylinder, the break angle, and how deep the fragment sits. Check whether any tools have already been used — pliers marks and screwdriver damage affect which approach is viable. Identify the cylinder type and lock family to select the right extractor.
Select Tool and Extract
First tool attempt: usually the hook extractor for fresh snaps on standard cylinders. If the fragment profile is wrong for hooks, switch to spiral or flat-blade. Most fragments come out in one to three tool attempts. The cylinder is kept free of compression throughout.
Check Cylinder Condition
Once the fragment is out, the cylinder is checked. Insert a key (or the bow end if available) and test whether it turns cleanly. Check for pin damage from the snap or from any previous extraction attempts. In most cases the cylinder is fine and just needs a key.
Cut a Replacement Key
If a working original key or the bow end is available, a replacement is cut from it. If there's no reference key, the pin heights in the cylinder can be decoded and a key cut from those measurements. This is included in the extraction service where standard key types allow it on site.
Replace if Needed — Upgraded on the Same Visit
If the cylinder is compromised — pins damaged, fragment pushed too deep, or existing failure that predated the snap — replacement happens on the same visit. Anti-snap TS007 upgrades are carried on the van. A snapped original cylinder is often the prompt to fit something better.
