Why Keys Snap — and Why the Fix Matters for Mortise Lock Systems
Keys break inside locks for a handful of predictable reasons: metal fatigue from years of use on a worn key blank, forcing a key that doesn't quite align with a sticky cylinder, extreme cold that stiffens internal components, or simply inserting a poorly cut duplicate. In Gary's older building stock — row houses near Pulaski Park, commercial blocks downtown, multi-family properties along Ridge Road — mortise lock systems are extremely common. A mortise lock is a full cartridge unit recessed into the door edge, and its cylinder is precisely fitted. When a key fragment lodges inside a mortise lock cylinder, it wedges against the internal pins or wafers in a way that makes improvised removal attempts genuinely risky. Trying to fish the piece out with a paperclip or bobby pin can push it deeper, score the cylinder walls, or displace delicate components that are expensive to replace.
This is where trained, insured technicians make a measurable difference. Our commercial locksmith team carries specialized broken key extractor picks, hook tools, and spiral extractors sized for the tight tolerances of mortise lock cylinders. We can often remove the fragment without pulling the entire lock body from the door — preserving the existing hardware, the door frame, and your security setup. For residential and commercial customers alike, a damage-free extraction means no emergency hardware purchase and no gap in your building's security during the repair window.
