Broken Key Extraction
That key had been bending a little for years, and you kept straightening it.
In plain words
Keys break for a reason, and finding that reason is half the visit. A brass key wears thinnest at its deepest cut, and after years of turning it fatigues there until a cold morning or a stiff bolt finishes it. Sometimes the lock is the culprit: grit in the keyway, a loose cap, worn pins, or a door that has dropped so the bolt binds and the key takes the strain. The extraction removes the piece; the inspection that follows tells you whether the lock needs a clean and lubricant, an adjustment, or a new cylinder, so it does not happen again next month.
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.

How the visit goes
Locked or unlocked right now
Whether the bolt is thrown changes the order of work. If the door is locked, extraction is the first half and getting you inside is the second; the locksmith plans both so the door is opened with the least fuss once the keyway is clear. If the key broke while you were locking up and the door is open, the priority reverses: the fragment comes out and the door is made secure before anything else is discussed, so you can leave when you need to. On a vehicle the same question applies to the door and, separately, to whether the ignition turns.
Bringing the plug back to rest
Nothing slides out of a rotated plug, because the pins that the key lifted are still sitting at the shear line and holding the blade. So when the key snapped mid-turn, the first job is to return the plug to its resting position. The locksmith applies gentle rotational pressure with a tension tool, feeling for the point where the pins drop back into the plug and the keyway lines up with the cylinder body. Sometimes a light tap on the face helps the pins settle. Only once the plug is at rest is the fragment free to move, and only then do the extractors go in.
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
Vehicle 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.
Weather on the day
A cylinder that is frozen or iced has to be thawed and dried before extraction can begin, so a call during a deep freeze carries that patient extra time.
How deep the fragment sits
A piece standing above the cylinder face is the simplest case. One flush with the face or deep behind the pins takes longer, finer work with hooks and spirals, and the quote reflects that.
What to have ready
- Do you have a spare key that works, or the key code tag from the lock?
- 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
QuestionsHow 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.
Why did my key break at all?
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.
What proof do I need to show?
Photo identification and something that connects you to the lock. For a house or apartment that is a lease, a bill, addressed post, or confirmation from the property manager; for a business, your role there; for a vehicle, the registration or ownership papers with matching identification. If the documents are inside, say so on the phone and the check is completed once the door is open.
