So I've been putting a little time and money into my 98 ECSB to get it back roadworthy, rebuilding the frontend mainly. At this point im waiting on parts to get here before I can finish her up. well being in the garage already got me to looking over my truck trying to find other things that may have been neglected that I could address while its down. one of the things I came across was the old key fob for the truck in the center console. I had all but forgotten that the truck had keyless entry. If my memory serves me right I think the fob just slowly lost range till I gave up on them altogether. I haven't used the keyless entry in probably at least 4 or 5 years. This is about the time the truck became a secondary vehicle rather than a primary. Now that I'm trying to get the keyless entry back going, I have two key fobs; one is the original 2 button GM 16245100-29 that I know for a fact worked on the truck at one point in its life, and one is a 3 button (LOCK, UNLOCK, AND THE RED ALARM SYMBOL) that I think came from a mid 2000 truck. GM/UTA 15732803. I purchased a new battery last night and set out to reprogram either of the remotes that I had. I jumpered #4 and #8 and the locks cycled but no amount of button pressing would program either remotes that I had in my possession.
So that long winded backstory leads me to my two main questions: If the locks cycled when jumpering pins 4 & 8 does that tell me that the keyless entry receiver in the dash is functioning properly? And, will the 3 button fob even work at all or do I need to throw it in the garbage and stick with the 2 button?
