Broken Key Extraction: inside the visit
Locksmith · Toronto, Ontario
Freezing is one of the bigger seasonal causes of broken keys here. Meltwater runs into the keyway during a thaw and freezes overnight, so the plug is locked in ice, and most people respond by turning harder. The blade gives before the ice does. A winter extraction visit therefore begins with thawing: lock de-icer or gentle warmth frees the plug, then the fragment is drawn out and the cylinder is dried and given the lubricant its maker specifies. You leave with the piece out, a new key cut, and a small tube of de-icer so the next frozen morning is a pause rather than a snap.
What has already been tried
Before choosing a tool the locksmith asks what has gone into the keyway since the break. Tweezers often push a fragment deeper; a screwdriver tip can bend pins; a drop of glue on the other half bonds to nothing useful and leaves a film that has to be dissolved before extractors will slide. A second key jammed on top of the first is a common find. None of this is anything to be embarrassed about; it just changes the plan, and knowing about it in advance means the right solvent, a plug follower or a spare cylinder is in the van before work starts.
Taking the cylinder apart to free it
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.
Habits that keep keys in one piece
A few small changes stop most repeat breaks. Push the key fully home before turning, and turn from the bow with a level hand, never with pliers or from the tip. Keep the house key off box-cutting and ice-scraping duty; every bend fatigues the blade at its narrowest cut. Replace a key the moment it shows a kink, a crack line or rounded cuts, and cut the replacement from code or a crisp original. Keep the ring light. If the lock itself starts to stiffen, that is the cue to lubricate or call, because a stiff lock is the one that breaks keys.
