Specs At A Glance

Good To Know

Q: Can I rekey these cylinders to match my existing key? A: These cylinders come precut and keyed together; they are not designed for rekeying. Use the included keys for all three locks.

Q: Do I need to reprogram the vehicle after replacing the ignition switch? A: If equipped with Passlock or VATS, a security relearn procedure may be required, but the mechanical switch itself is plug-and-play.

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