03 GMC Sierra - Key fob lock, but no unlock
Recently on my 03 Sierra, my key fob stopped unlocking the doors. The lock and panic buttons work, but not the unlock. Changed the battery in the fob, still unlock does not work. Tried a 2nd fob that I have with the same result. Must be the truck... I've heard others have experienced this. I've checked fuses, relays without success. Any fixes?
