- The call
- In the parking lot your car key snapped in the driver's door. You are holding the plastic head with the buttons on it, the metal blade is inside the lock, and the spare is on a hook at home.

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.
The tools are simple and precise. A hook extractor is a thin strip of spring steel with a barb at the tip; it slides along the groove of the keyway above or below the fragment, snags one of the cuts, and walks it out. A spiral extractor works like a tiny screw, threading into the ridges of the cuts and gripping as it turns. Fine-tipped extractor pliers handle a piece that shows above the face. A tension tool brings a turned plug back to rest. None of these push inward, which is the whole point: the piece comes out the way it went in and the cylinder stays whole.

Broken Key Extraction · East Zorra-Tavistock

Scene 1
Even a lock in good order can break a key that was already worn, bent or fatigued, so the cylinder is examined for a contributing cause all the same. The locksmith looks for grit and salt crust in the keyway, a cylinder cap that has loosened and let the plug shift, pins that have worn flat so the key needs force to lift them, springs that have weakened, and burrs at the mouth of the keyway that drag on the blade. On an exterior door the strike and hinges are checked as well, since a bolt that binds in its pocket makes the key carry the load. Each finding shapes the advice given once the fragment is out.
Scene 2
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 The pins are lifted clear as the piece passes them, exactly as they are when a key is withdrawn.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.
Scene 3
A few small changes stop most repeat breaks. Push the key fully home before turning, and turn from the bow with a level hand, never with pliers or from the tip. Keep the house key off box-cutting and ice-scraping duty; every bend fatigues the blade at its narrowest cut. Replace a key the moment it shows a kink, a crack line or rounded cuts, and cut the replacement from code or a crisp original. Keep the ring light. If the lock itself starts to stiffen, that is the cue to lubricate or call, because a stiff lock is the one that breaks keys.

FeesSame any hour
Yes. The fragment comes out first, because nothing else can happen while it blocks the keyway. With the cylinder clear and the plug at rest, the door is opened by the same non-destructive methods used for any lockout, then a working key is cut and tested. If the door is a rental, the visit is noted for the building manager on request.
Often fatigue, though not the only cause. A brass blade is weakest where the deepest cut leaves the least metal, and thousands of turns can slowly work a crack into that spot. Then one morning something asks more of it: a frozen cylinder, a bolt binding in a swollen door, grit in the keyway, or turning before the key was fully in. A bent, worn or poorly cut key can also fail on its own, with no such trigger. The lock is inspected afterwards to find which applied.
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.
