DIY Remote Programming Instructions For GM Vehicles

This blog shows the On-Board-Programming or DIY programming for Buick, Cadillac, Chevrolet, Oldsmobile and Pontiac vehicle remotes sold at carlocksandkeys.com. If you don't see your GM vehicle listed here, then your vehicle probably doesn't support On-Board-Programming and you need your dealership or locksmith to configure your car to recognize the new remote. 

Always remember your battery should be fully charged and in good working order whenever doing any On-Board-Programming.
