- The call
- You were locking up on the way out when the key broke in the lock. Now the door is unlocked, a piece of key is jammed in the cylinder, and you were already running late for work.

Overnight the deadbolt froze, and this morning the key would only turn partway. One more push and it sheared off flush with the face of the cylinder.
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 · Peterborough

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
A cylinder that broke a key because it was frozen needs the ice dealt with before the fragment will move. The locksmith works lock de-icer into the keyway, or holds gentle heat near the cylinder, until the ice inside liquefies and the plug loosens. Boiling water from the kettle stays indoors: it refreezes inside the keyway and can split a cold cylinder. With the plug free and at rest, the extraction proceeds as normal. Afterwards the cylinder is dried thoroughly and given a water-repelling dry lubricant rather than one that traps moisture, so the same morning is far less likely to repeat.
Scene 3
If the bolt had been dragging in its strike, that is corrected while the locksmith is there, because a bolt that binds turns every key into a lever. Dropped hinges get longer screws driven into the framing; a strike pocket that pinches the bolt is filed or shifted; a weatherstrip that was pushing the door off square is pared back. The test is simple: the thumb-turn should throw the bolt with one finger and no push on the door. Since wood swells in humid summers and shrinks in dry winter air, a seasonal glance at the screws keeps the key from taking the strain again.

It is rare, and it is discussed before anything changes. A glued, jammed or corroded-in fragment can usually still be reached by taking the cylinder off the door and working the plug out from the back. If even that fails, the cylinder is drilled where plug meets housing, sacrificed and replaced on the spot with new keys cut, so the door locks normally by the time the locksmith leaves.
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.
Put both halves of the key somewhere safe, note whether the door or vehicle is locked, and leave the keyway alone. If it is bitter cold, keep the storm door closed so the lock is not taking freezing rain. Have identification ready, or vehicle papers for a car. If the door is open, stay near it. That is all; the extraction goes smoother for a lock nobody has poked at.
