Like evank33 mentioned, it’ll just work. Also, it’s been discovered that the circuit for the release button is already on the fob circuit board (and remote start also) for the HD Rams, so I’m guessing they are there on the DT fobs. You could buy some 4 pin buttons, and solder them in place. You won’t have the labeling on the fob overlay, but they will work when pressed. This will eliminate a dealer visit altogether if you have AlfaOBD to enable remote start (tailgate remote release will work no matter what).
