- 1). Look up your GM car's make, model and year at programyourremote.com. This is by far the first place to look, if you don't have the instructions in your owner's manual. The site has around three dozen makes and breaks down the instructions by model and model year. Navigation of the site is self-explanatory.
- 2). Find your GM car's manual on ownersmanualsource.com. The GM cars featured there are Buick, Cadillac, Chevrolet, GMC, Hummer, Pontiac, Oldsmobile and Saturn. Navigation of the site is self-explanatory.
- 3). Call around to different GM dealerships, but only as a last resort. You may want to call dealers outside of your area, eliminating their motive to withhold programming instructions in order to rope you into the store for them to perform the service.
