Why Keys Snap — and Why the Lock Type Changes Everything
Keys break for predictable reasons: metal fatigue from years of daily use, a worn or sticky lock cylinder that requires extra torque, a key that was already bent or poorly duplicated, or the simple bad luck of forcing a stiff lock in cold Westchester winters. The fragment that stays behind varies in position — it may sit flush with the keyway, recessed deep in the cylinder, or wedged at an angle. Each scenario calls for a different extraction approach, and the type of lock involved is the single biggest factor in determining which tools and technique are appropriate.
A traditional mortise lock — the type commonly found in older Victorian and Colonial-style homes throughout Pleasantville's historic districts, as well as in many of the village's commercial storefronts — presents a particularly nuanced challenge. Mortise lock cylinders are integrated into a substantial lock body recessed within the door, and the keyway profile can be tighter than a standard cylindrical lock. Our technicians who specialize in mortise lock work understand that forcing the cylinder or using generic extraction hooks can crack the cam or damage the internal bolt mechanism, which then requires a full mortise lock replacement rather than a simple extraction. Damage-free removal is always the goal, and with a mortise lock that goal demands experienced hands.
