Hello all, I just bought a 2018 2500HD Denali. My key fob does not work, I've tried to program it and no luck. When I try to put the truck into program mode using the Unlock Button on door and cycle key twice I get nothing but I can put the truck in fob learn mode with my snapon scanner, have tried two fobs, new batteries and truck will not recognize it.

 

Any ideas?
