- 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.

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.
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.

Broken Key Extraction · Hamilton

Scene 1
A car adds a few questions. Did the key break in the door, the trunk or the ignition? Does the head in your hand hold a transponder chip or remote, and does the car start with the spare if there is one? Is the steering wheel locked, which can hold an ignition cylinder under tension and pin the fragment in place? Do the other doors open with the same key, or is the vehicle on a different key for the ignition and doors? These answers decide whether the job is a door extraction and a new blade, or an ignition extraction that needs the wheel freed and the wafers checked first.
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.
