Installation Notes

Verify the vehicle uses the winged-type ignition lock cylinder and does not have RPO code BAE before ordering. Compare the existing cylinder shape and keyway to the replacement part, and follow the included instructions during installation. Because this is a non-programmable ignition lock cylinder, no key programming is required.
