Lock cylinders are the physical keyed mechanism behind door locks, ignition switches, and trunk or tailgate latches, and lock kits pair a set of cylinders together for keyed-alike convenience or a matched replacement. A worn cylinder can leave a key that won't turn, sticks, or spins without engaging, while a damaged one is also a common target for forced entry or ignition tampering. Browse replacement lock cylinders and lock kits for cars, trucks, and SUVs to restore secure, reliable operation to your doors, ignition, and trunk.
