Good To Know

Q: Can this ignition lock cylinder be rekeyed to match my door key? A: Yes, a locksmith can rekey the tumblers so your original key operates this cylinder and all door locks, keeping a single key for your truck.

Q: Will it work with the factory anti-theft (PASSlock) system? A: The cylinder is designed for standard key ignitions; if your Silverado or Sierra uses a transponder key, you may need to transfer the sensor module from the old lock cylinder.

Slight variation in finish or dimensions may occur between production runs, and fit can depend on serial number, so confirm compatibility before ordering.
