Ok, just got an 08 Silverado, power locks, but no keyless entry. The build sheet on the truck says it has it. The dealer says that the other options cancelled that out. There is no AU0 in the glovebox. However the dealer is going to give me keyless as long as all they have to do is program the fobs. What are the chances it actually is set up with keyless entry and just needs the fobs programmed to work? If not what is required to get factory keyless? Thanks for any info.
