I'm trying to program my new remote I got off e-bay, but I'm running into a problem when following the instructions posted in the group regarding the results from the "pull the key out of the ignition
you should hear the door locks go lock\unlock twice" part of the procedure. The locks do nothing. My question is, what is a master key and how do I know if the truck had/needs one?

Thanks,

Marty
