- 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.

A 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.
A car key that breaks in the door or the ignition is handled with the same extraction tools, with one difference. On most vehicles the plastic head of the key carries the transponder chip and the remote buttons, and that half is usually intact in your hand. Once the blade is drawn out of the lock, a new blade can often be cut and fitted to the existing head, so the chip keeps talking to the car without reprogramming. The ignition wafers are checked for disturbance and the steering lock is confirmed free. Proof of ownership is asked for before work begins.

Broken Key Extraction · West Hamilton

Scene 1
The first look is at the fragment itself, without touching it. Does any of the blade show above the cylinder face, or is it flush or deeper still? Is the plug sitting at its normal rest position, or did it stop partway round when the key gave way? A protruding piece in a resting plug is the simplest case. A fragment past the shear line in a rotated plug means the pins are holding it, and the plug has to be brought back before anything will slide. Reading this correctly decides which extractor comes out of the case and spares the keyway from needless probing.
Scene 2
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.
Scene 3
A winter break leaves you with a dried, lubricated cylinder and one rule: when the key stops partway, you stop too. Carry a small lock de-icer in a coat pocket or the glovebox; a few seconds of it, or the warmth of a cupped hand on the cylinder, frees a frozen plug without asking anything of the blade. Shut the storm door before freezing rain, and fit a keyhole cover on a side door that catches meltwater during a thaw. Ice is one of the winter causes the locksmith sees often, alongside worn keys, misalignment and dirty or worn cylinders, and it is one of the easiest to prevent.

Only if the inspection finds a reason. A clean cylinder with sound pins goes straight back to work with a new key. Rekeying makes sense when the pins are worn and sticking, or when a lost or unaccounted key shares the same cut. Replacement is for a cylinder that is corroded, cracked or of a grade that will keep eating keys. Each is offered as its own decision, not bundled in.
It helps if there is one. A crisp spare is the ideal pattern for the replacement, better than the broken halves and far better than a worn copy. It also lets the locksmith test the cylinder the moment the fragment is out, which shows whether the pins and springs are sound. If the spare is itself bent or worn, mention that too; it is a candidate for retirement rather than a pattern.
A daytime thaw sends meltwater into the keyway, and overnight it freezes with the plug held solid. The key goes in, meets resistance, and the natural reaction is to turn harder. Brass gives before ice does, especially at a deep cut that has thinned over years. Cold also stiffens old grease in the cylinder. De-icer, gentle warmth and a dry lubricant break the pattern.
