Key won't unlock doors
Key for the newest Crossfire stopped working this week -- cannot lock/unlock doors. (Have not tried to start car, though.) Went to backup key and it worked fine. I suspect dead battery in key fob but before I go to the dealer for new battery + install, I thought I'd ask for a sanity check on my diagnosis. I do have Tom's write up for taking fob apart, but meticulous effort is beyond my patience and I'd rather pay the dealer so if he messes up, he's responsible.
Gripe: I have two keys each for 2005's which both work great. Why would a key for a 2 year newer car fail so soon?
