Broken Key Extraction
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.
Broken Key Extraction
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 goesThe 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. You are on the wrong side of the door.

How the visit goes
Reading the cylinder for the cause
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.
Thawing first on a frozen lock
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.
A cylinder that has been looked after
Extraction usually doubles as a service. The keyway has been blown clear of grit and salt, the pins and springs checked for wear, the cylinder cap snugged if it had loosened, and dressed with the lubricant its maker specifies rather than a one-size-fits-all product, since some cylinders take a dry graphite or PTFE spray and others forbid graphite outright. General household oils and sprays commonly collect dust and clog the pin chambers. A puff of the right lubricant twice a year, spring and fall, keeps the cylinder turning freely, and a key that starts to need force is an early message worth acting on before it breaks.

What affects the quote
Same fees day, night or weekend
1Number of keys cut
Copies are counted individually. One replacement for a single occupant and four for a household are different lines, and you choose the number on the spot.
2Where 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.
3Drilling 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.
Broken Key Extraction: questions
What should I do while I wait for the locksmith?
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.
How do I stop keys breaking in future?
Look after the lock and the key ages slowly. Keep the cylinder lubricated with the product its maker specifies and free of grit, and have a binding door adjusted, since resistance raises the risk, though a worn, bent or fatigued key can still fail under normal use. Retire copies that have gone thin or kinked instead of straightening them. Cut spares from code, and rotate them so one key is not doing all the work. Take the ring weight off a car key. Small habits, but they add years.
My key has a chip in it. Does that survive the break?
Usually yes. The transponder chip and the remote electronics live in the plastic head, and the head is the part that stays in your hand when the blade snaps. Once the blade is extracted, a new blade of the right profile is cut and fitted to the old head, so the vehicle continues to recognize the chip without reprogramming. Only a cracked or soaked head needs the electronics moved to a new shell.
