Why Broken Key Extraction Demands a Professional Touch
A key breaks inside a lock for several reasons: metal fatigue from years of use, a lock cylinder that has stiffened from lack of lubrication, a duplicate key cut slightly off-tolerance, or simply applying too much lateral force while the lock is under tension. The fragment that remains is usually slick, flush with the keyway face, and wedged into the warding grooves that make extraction deceptively difficult. Standard household tools cannot grip a broken key edge without slipping, and every failed attempt risks bending the fragment or packing it tighter against the pin stacks. Our technicians assess the keyway geometry, the depth of the fragment, and the lock type before selecting the right hook pick, extractor, or jig — a process that looks simple only because it is done correctly.
This is especially critical with mortise lock cylinders, which are common in older Hammond commercial buildings and multi-unit residential properties. A mortise lock sits recessed inside the door stave and routes through a complex internal mechanism; a fragment driven too deep can jam the case entirely, requiring the entire mortise cartridge to be disassembled. Catching the problem early and calling a professional protects not just the cylinder but the full lockset investment — mortise hardware is precision equipment and replacement is significantly more involved than swapping a standard knob-lock cylinder.
