Review on SCITOO 1pc KOBUT1BT Key Fob Keyless Entry Remote: Compatible with Oldsmobile Bravada, Chevrolet Suburban 1500, and GMC Sonoma by Ben Balas

Purchased for a 1999 Chevy Silverado 1500. The product has not been programmed. No documents came with the product. Had to contact seller through Revain for programming instructions. They were easy to follow, but they didn't complete the software processing. After many attempts I finally gave up. Not recommended without further information. ----- Whether pre-programmed and for which vehicle. If it's not preprogrammed for your car, don't do it. Receiving instructions and stepping through the programming process is not user friendly.
