My 2001 GMC Sierra seemed to have two remote control options. Apparently it wasn't one of them. The number they are asking for is not on the back of my existing remote nor is it on the inside of the circuit board. This one is the same form factor so I used a packet and a silicone carbon pad, sanded down the gold pins on my existing board - voila! Requires no programming and works. Consider just buying a suitcase and saving yourself a lot of hassle. Oh, and the new remote control that came has no numbers inside or outside, nada, lightning. The next exchange cycle will also have no numbers to refer to.
