Broken Key Extraction in The Golden Mile
Overnight the deadbolt froze, and this morning the key would only turn partway.
In plain words
Two facts shape the job before the locksmith arrives: whether the door is locked or unlocked, and whether any of the key is showing. A fragment that protrudes can often be gripped and drawn straight out. One flush or deep needs extractors worked in alongside it. If the plug turned before the key broke, it has to be eased back to its resting position first so the pins line up and release the blade. A locked door means the extraction is followed by opening the lock; an unlocked one means securing it is the priority. Either way the door ends up locking with a key that fits.
How the visit goesA roommate tried to help with tweezers, then by gluing the other half to it. The fragment is now further in than it started, there is dried glue around the keyway, and the front door still does not open.
Broken Key Extraction
How the visit goes
What has already been tried
Before choosing a tool the locksmith asks what has gone into the keyway since the break. Tweezers often push a fragment deeper; a screwdriver tip can bend pins; a drop of glue on the other half bonds to nothing useful and leaves a film that has to be dissolved before extractors will slide. A second key jammed on top of the first is a common find. None of this is anything to be embarrassed about; it just changes the plan, and knowing about it in advance means the right solvent, a plug follower or a spare cylinder is in the van before work starts.
Drawing it out with a hook extractor
Every keyway has grooves, called wards, that run along its length above and below the blade. A hook extractor is a slim strip of spring steel thin enough to ride in one of those grooves beside the fragment. The locksmith slides it in past the broken piece, rotates it slightly so the barbed tip catches a cut in the blade, and draws it back out in a straight line. The pins are lifted clear as the piece passes them, exactly as they are when a key is withdrawn. It is a patient, felt process, and the cylinder is untouched by it.
Habits for the freezing months
A winter break leaves you with a dried, lubricated cylinder and one rule: when the key stops partway, you stop too. Carry a small lock de-icer in a coat pocket or the glovebox; a few seconds of it, or the warmth of a cupped hand on the cylinder, frees a frozen plug without asking anything of the blade. Shut the storm door before freezing rain, and fit a keyhole cover on a side door that catches meltwater during a thaw. Ice is one of the winter causes the locksmith sees often, alongside worn keys, misalignment and dirty or worn cylinders, and it is one of the easiest to prevent.

What affects the quote
Removing the cylinder to free it
A deep or bound fragment may need the cylinder taken off the door and the plug pushed out from behind on the bench. That disassembly and reassembly is quoted on its own.
Where the key broke
A house deadbolt, a knob, an older mortise case, a padlock, a car door and a vehicle ignition each call for different access and different care, and the quote follows the hardware.
Whether the plug turned before the break
A key that snapped mid-turn leaves the plug rotated and the pins holding the fragment. Easing the plug back to rest before extraction is an extra step in the work.
What to have ready
- Is the door or vehicle locked or unlocked right now?
- Is any part of the key still visible above the face of the lock?
- Had the key been needing extra force or a wiggle lately?
Broken Key Extraction: questions
QuestionsDoes the glue trick work?
It is a well-known idea and a poor one. A drop of adhesive on the other half rarely bonds to a piece of brass sitting in a tight keyway, and what it does bond to is the cylinder, the pins and the face of the lock. That film then has to be dissolved before proper extractors can slide in. Keep the halves apart and dry.
It broke while I was locking up and now the door is open. What should I do?
Stay with the door if you can, or ask a neighbour to keep an eye on it, and call. When the locksmith arrives the fragment is removed and securing the door comes ahead of everything else, so you can leave. If the cylinder needs more than a clean, a replacement goes on during that visit rather than leaving the door on a latch overnight.
Part of the key is sticking out. Can I just pull it with pliers?
If a good length shows and the plug is at its normal rest position, a firm straight pull sometimes works. The risk is pushing instead of pulling, or twisting, which drives the piece deeper and can bend a pin. If it does not come on the first gentle try, stop there and leave it for extractor tools, which grip the cuts without loading the cylinder.
