- The call
- The padlock on the shed has been stiff all summer. Today the key twisted, cracked at the tip, and left the end buried deep in the keyway. The rest came out in your hand, and the padlock is still closed.

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.
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.

Broken Key Extraction · Corktown

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
Occasionally a piece is too deep, glued in, or wedged past the pins where no extractor can reach. On a serviceable, removable cylinder, the lock is serviced from behind: removed from the door or padlock (a rekeyable padlock is normally unlocked first), its cap or retaining clip taken off, and a plug follower used to push the plug out while the top pins and springs stay in place. With the plug in hand the fragment is tapped out from the rear, the pins inspected, and everything cleaned before reassembly. Where the cylinder is non-rekeyable, damaged or will not free this way, a replacement cylinder is the alternative, explained first.
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.
