How do you program a 1995 Suburban remote?

Answer 1

Walk out to the vehicle with the fob, press the lock and unlock buttons at the same time and HOLD them pressed for 7 seconds and you will hear the locks go thru a cycle. After 7 seconds the fob should be reprogrammed. Try it. If not stand closer. I stood beside the front driver's fender to do mine and it worked first time.

that means all that is required to gain entry to all such vehicles is a similar remote.

are you sure about this ?
