Broken Key Extraction
The apartment key snapped mid-turn, leaving the cylinder twisted halfway between locked and open. The building manager's spare is somewhere across town and nobody else has a copy.
Broken Key Extraction
In plain words
What you have when the locksmith leaves matters as much as what was removed. The fragment is out and shown to you. The cylinder has been cleaned of grit, its pins and springs checked, and dressed with the lubricant its maker specifies. A new key has been cut from the key code or by reading the cuts on the two halves with a gauge, not copied from a worn original, and tested from both sides with the door open and closed. If the key broke because the lock was on its way out, a rekey or a replacement cylinder is offered as its own decision, explained first.
How the visit goesThe padlock on the shed has been stiff all summer. Today the key twisted, cracked at the tip, and left the end buried deep in the keyway. The rest came out in your hand, and the padlock is still closed.

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.
Taking the cylinder apart to free it
Occasionally a piece is too deep, glued in, or wedged past the pins where no extractor can reach. On a serviceable, removable cylinder, the lock is serviced from behind: removed from the door or padlock (a rekeyable padlock is normally unlocked first), its cap or retaining clip taken off, and a plug follower used to push the plug out while the top pins and springs stay in place. With the plug in hand the fragment is tapped out from the rear, the pins inspected, and everything cleaned before reassembly. Where the cylinder is non-rekeyable, damaged or will not free this way, a replacement cylinder is the alternative, explained first.
Your car key, rebuilt rather than replaced
For a vehicle, the head of the key that carries the transponder chip and remote buttons has usually been saved, and a new blade cut and fitted to it, so the car recognizes the key as it always did. The door lock and ignition have been tested with it, and the ignition wafers checked for damage from the break. It is a good moment to have a second complete key made, since a car with one key is a car one snap away from a tow. Lightening the key ring so it does not hang on the ignition adds years to both key and cylinder.

What affects the quote
Same fees day, night or weekend
1Locked or unlocked door
If the door is locked, the extraction is followed by opening it, which is quoted as its own part of the visit. If the door is open, the work is extraction and securing.
2Drilling and a replacement cylinder
On the rare occasion a cylinder must be sacrificed, the price includes the new cylinder or complete deadbolt plus fitting it, and that is agreed with you before the drill is picked up.
3Vehicle key electronics
Fitting a new blade to a chip head, or moving the chip and remote into a new shell, is separate from the extraction and quoted as such, as is any ignition check.
Broken Key Extraction: questions
Can a new key be made from the two broken halves?
Usually. Laid end to end, the halves show the full set of cuts and identify the blank, and a locksmith reads them with a gauge and cuts a fresh key to those depths on a code machine. That is better than tracing the broken blade on a duplicator, because a worn key copied is a worn key repeated. If a spare or the key code exists, that is used instead.
Will the lock work again once the piece is out?
In most cases yes, and it is tested in front of you with a key that fits. The inspection after extraction is where the honest answer lives: if the pins, springs and cap are sound and the keyway is clean, the cylinder goes back into service with a fresh key. If wear or damage caused the break, that is explained and a rekey or new cylinder is offered as a separate choice.
How long does the extraction usually take?
It depends on how the piece is sitting. A protruding fragment in a plug at rest can be out in moments. A deep piece behind lifted pins takes patient work with hooks and spirals. A glued or corroded fragment may mean removing the cylinder and freeing it from behind. Cutting and testing the new key, and any door adjustment, add their own time. The locksmith gives a sense of it after the first look.
