Why Keys Snap — And Why the Lock Type Changes Everything
Keys break for a combination of reasons: metal fatigue from years of daily use, a hairline crack from a previous bend or drop, a cylinder that has started to bind due to worn tumblers or misalignment, or simply the leverage applied when someone forces a key that does not quite seat correctly. Residential door knob locks and standard deadbolts are common culprits because their keyways are narrow and the torque applied is usually harder than people realize. Mortise locks — the heavy rectangular units recessed into the edge of a door and widely used on older Irvington homes, apartment buildings, and commercial properties throughout the area — present a different challenge. Their cylinders sit deeper within the case, the keyway geometry varies by manufacturer, and the internal cam mechanism means any technique that pushes the fragment further can jam the lock entirely. Understanding what is inside the lock before any tool touches it is the first step our technicians take on every call.
Vehicle locks add yet another layer of complexity. Transponder-cut and laser-cut car keys are harder metals and tend to shear at an angle rather than straight across, leaving an irregular fragment that grips the wafer or pin stack tightly. Irvington Locksmith Pro provides vehicle locksmith services as part of our full mobile offering, so whether you are dealing with a snapped key in an ignition cylinder or a broken blade in a door lock on a car parked near Maplewood Avenue, we have the extraction tools and the key-cutting equipment on board to get you moving again.
