How do you program the key fob on a 1996 GMC Safari?

Answer 1

sit in drivers seat with all doors closed. hold the door lock button in the unlock position while rotating the ignition key from lock to on (do not start) position,back to lock, back to on ,thenback to lock. release door unlock button. door locks should cycle twice to indicate programming mode is activated. take fob and depress both lock and unlock buttons at the same time for 15 seconds. locks will cycle when fob frequency is accepted. test fob. lock,unlock etc. additional fobs may be programed at this time by holding both lock and unlock buttons down on fob until door locks cycle. test that fob for function. rotate ignition key to on position to exit activation program.
