What Causes Keys to Break in the Ignition — and Why It Matters
Keys fail inside ignitions for a predictable set of reasons: metal fatigue from years of heavy key rings torquing the blade, worn ignition wafers that catch the key at odd angles, attempted forced starts, or a cylinder that has begun to corrode from moisture exposure. Port Chester winters are no joke — freeze-thaw cycles can cause metal components to expand and contract repeatedly, accelerating wear inside cylinder housings. When a key finally snaps, the break rarely happens cleanly at the bow. Fragments lodge deep inside the cylinder, sometimes spinning or jamming the plug entirely, which means a standard spare key will not even engage until the broken piece is fully removed.
Attempting to extract a broken key without the right tools almost always makes the situation worse. Improvised tools like bobby pins or tweezers can push the fragment deeper, score the internal wafers, or break off additional pieces inside the chamber. Our technicians carry specialized hook picks, extractor kits, and plug followers purpose-built for this work. We assess the depth and orientation of the fragment first, then remove it using a method matched to your specific lock or cylinder type — all while keeping collateral damage to an absolute minimum.
