A key snapped off in the door or ignition is stressful, but an auto locksmith can extract the broken piece and cut a fresh working key without damaging the lock.
Keys usually break because they are worn thin, bent, or forced in a sticky lock. Once a piece is lodged in the cylinder, pushing or turning it can drive the fragment deeper or damage the wafers, so it is best to stop and call a professional. A locksmith uses extraction tools that grip and withdraw the broken piece cleanly.
After extraction, the locksmith can cut a new key by code or by decoding the lock, and program it if your vehicle uses a transponder. Because the original key was already worn or weak, replacing it rather than reusing a repaired fragment prevents a repeat break. This is a good time to cut a spare so you are never left with a single key.
