A competent locksmith can sometimes program these newer Remotes on CAN bus communication systems. Even if the remote is still sending out a signal , it doesn't necessarily mean its still good. In most cases from my experience, if the wireless control module ( WCM) will not recognize the code of the FOB after attempting to reprogram it, it's never going to work . Replacement is the only option after that. FYI, the process of programming a key or a fob requires a PIN code from Chrysler therefore is usually suggested to be brought to a dealer.
