I've got a new wireless entry fob for my 2002 and I can't for the life of me figure out how to program it. It has the keyless transmitter with the button instead of the pink wire, and I've tried holding it down and turning the key on/off 4x and I've tried holding it down for 30 seconds while turning the ignition on as I've read either on flash off road or the hummer network knowledge base.

Is there any other method that someone's heard of?

 

hummech can walk you through it. It isn't hard but sometimes you have to do it three or four times.
