If the combo FOB/Key, I would seek out a local locksmith for that and just expect to pay the tax on that. FCA vehicles are a pisser to try to do a DIY fob replacement most times do to the PIN lock codes that have to be extracted from the dealership tool or through an actual locksmith that has registration in the trade to use special program pass protection to extract it. Many of the so called high level scan tools will have a menu to get the pin, but it will usually require you to go through a third party host that verifies your credentials of being in the locksmith trade or being a dealer level tech.
