I just bought a 06 HD2500 and it didn't have the key fobs with it. I have one left over from my 02 HD2500. Does anyone know if it will work on the newer truck and if so how to program it? Also does anyone know if they put a factory remote start on these and how to tell? Its an LT with pretty much everything else. If not I want to have one installed, but if there is already a factory one there I might try to just get new remotes. I can't believe how much I miss being able to lock/unlock with a remote! Thanks in advance.
