Key and Lock Cylinder Coding: Notes
WARNING: This page is about a different car, the 2009 Saturn Vue. However, it is still accessible from the selected car via links, so may be relevant.
This vehicle has two different types of ignition lock cylinders based on what type of steering column the vehicle is equipped with. The electric power steering (EPS) option, usually found on 4 cylinder models, and the non EPS, usually found on 6 cylinder models, use different ignition lock cylinder designs.
