Newdude - do you know if this is the same on the Express Vans? I have a 2014 with no key fobs, but with On-Star, Cargo, Duramax if it makes a difference. AU3 RPO code. Dealer tried 3 times to order key fobs, 3 button, 4 button (cargo door separate) & 5 button (remote start) and could not get any to pair with the RCDLR /TPMS receiver. I ran this information and VIN past Dorman when I tried one of their programming modules & fob and they ran the VIN said I am missing the key fob receiver. But I have TPMS and the receiver is the same part number. SO..... Do I need a different RCDLR receiver (part number 20863945) and have the BCM reprogrammed to use this new key fob / TPMS receiver? My dealer doesn't seem to understand this stuff. They also said just buy an aftermarket remote / alarm.
