Smart move to get the 2 key Crossfire. I bought 8 original key fobs as a lot paid $40 for all 8 original Crossfire key fobs . I felt I got a bargain even if they don't start my car. This Spring I wanna see if I can program the remotes to unlock at least the doors. I think they are also vin #specific . It's cold here I have no garage to take ignition out to see if I can see if the remote locks can be activated once I use the last usable key with transponder key is close to transponder ring with ignition is turned to run position to see if I can activate the bought used remotes . Guess I will see once weather gets warmer. 😁
