I have a 2006 Trailblazer LS
Bought it used and it came with a 'generic' remote fob. The fob functions just fine but the plastic ring that attaches it to my keyring broke so I bought a replacement GM fob from Ebay.
The fob came with the standard programming instructions (hold door unlock, cycle the key 2x etc) but I can't get the truck into programming mode.
Immediately as I bring the key back to "off" the second time, the locks cycle, then they cycle again about 5 seconds later. I think they're only supposed to cycle once. I've tried releasing the lock button on the door both before the second cycle and after, then holding the buttons on the remote. cannot get the remote to program.
I know the keyless entry system goes through the liftgate control module on this truck. I noted a while back that the rear wipers don't work, however everything else does-window, power locks and, as mentioned my old key fob works fine.
Any ideas?
