Specs At A Glance

Good To Know

Q: Will my old key work with this new lock cylinder? A: No, this assembly comes with its own set of keys matched to the new cylinder. If your vehicle utilizes an immobilizer chip, you will need to transfer the chip or program the new keys to your vehicle.

Q: What causes the ignition key to stick or fail to turn? A: Over time, internal metal tumblers and key paths wear down, causing mechanical binding which eventually prevents the key from turning inside the cylinder.

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