2003 C320 Wagon... Just got it.. someone got sedan keys to program for it and now only the hatch unlocks via the truck button via the sedan keys. How do I fix this? Any thoughts?

 

Are you saying that the unlock button does nothing?

Does the red light flash when it is pushed?

 

All the remotes unlock the 4 doors with the unlock button I have 2 wagon remotes and 2 sedan remotes. So right now the only way to get into the hatch not even the handle on the hatch is vehicle off and the trunk button on the sedan remote
