Does anyone know how to do it? PLEASE help.

Transmitter Programming
Start with the ignition OFF, hold down the power unlock button on the door panel.
Turn ignition key ON, OFF, ON, OFF. Release power unlock button on the door panel. The locks will cycle once.
Hold down the keyless entry transmitter LOCK and UNLOCK buttons for 15 seconds. The locks will again cycle once.
Repeat step #2 for each additional keyless entry transmitter.
Turn the ignition on to exit the keyless entry transmitter programming mode. Programming is now complete.

I bought this truck used. I was given a new remote. When I Try to program the Yukon the locks never cycle letting me know its in thw program mode. It there a test to see if the reciever in the truck is good?

If you followed the procedure and the locks won't cycle.....you are looking at a bad receiver:frown:

Have 97 Yukon, SLT, I cant get the remotes (2) to work at all, changed batteries but still do not work.....Could it be the receiver that is located in the vehicle....not sure where the reciever would be located....Can you help?

I just bought a 99 yukon and following this procedure does not cycle the locks. I am sure the equipment is good as the remote transmitter that came with the vehicle works.

Any chance there are different procedures?
