Hi, I am trying to program a new key fob but I cannot get the vehicle in the learn mode. This is a K1500 old body style. I have tried holding the door unlock button down and cycling the key method and it does not work. I have also read to short pin 4 and 8 together on the data port to enter "learn Mode". I would like to confirm this is a safe method before trying it. Anyone know? I have also checked the fuse and it is fine.
Do you
have the same problem?
