Hi....We've just bought a 2006 Grand Voyager 3.3 CRD XS, only got one key and one 5 button transponder to operate the doors and tailgate. have managed to obtain a second transponder but I need to know how to program it... do I really have to go to Chrysler or is there anyone out there who knows how to do it? I believe Jeep transponders can be programmed easily using the ignition key and entering some sort of code, so I wonder if the Voyager maybe similar. Can anyone help please?. Thank You in anticipation!!!
