Why Keys Snap — and Why a Mortise Lock Complicates Things
Keys break inside locks for a handful of predictable reasons: metal fatigue from years of use, a key that was cut slightly off-spec, forcing a key that doesn't turn smoothly, or simply the stress of a cold New York winter morning when metal contracts and a stiff cylinder demands extra torque. Most residential door knob locks have relatively short cylinders, so a fragment sits close to the face of the plug and is somewhat accessible. A mortise lock — the style found in countless historic homes and commercial buildings throughout New Paltz — is a different story entirely. The cylinder sits inside a deep mortise case recessed into the door edge, and the broken fragment may be seated several inches into the mechanism, well beyond what any improvised tool can safely reach.
Mortise lock hardware is common on the older Victorian and craftsman-era properties along North Chestnut Street and in the historic district, as well as in many of the stone houses unique to this part of the Hudson Valley. Because the lock case is integrated into the door itself, any heavy-handed extraction attempt risks damaging the case, the tailpiece, or the surrounding door material — repairs that cost far more than a proper professional extraction. Our technicians carry specialized broken-key extractor sets sized for standard pin-tumbler cylinders as well as the longer, narrower profiles common in mortise lock hardware, so the right tool is always available regardless of your lock type.
