I am trying to program my keyless on my 1997 jimmy. On the current controller that works, the unlock button doesn;t work so I am trying to replace it. I can get it into program mode using a jumper from ground to #8. The car locks,unlocks, and the hatch pops. Then what do I do?
This is what I've tried:
1: hold any button individually for 2 seconds
2: same as one for a longer period of time
3: hold unlock/lock for 2 secs and long time.
I performed these all with the wire still attached and also tried all these after letting go when the truck lock/unlock/pop hatch. I even tried these with the currently(old) working controller and it didn;t even lock/unlock like its supposed to in program mode.
When i try this with the working(old) controller, it won't even lock when its in program mode so I KNOW its in program mode. Then if I pull the wire, the current(old) transmitter will work again.
