Here is one for the gurus of Crossfire key fobs

1. 2007 Crossfire convertible worked fine. Yesterday went to the parking lot and the key fob did not unlock the doors. Changed batteries car did not unlock. Read the manual, read this forum, and read general internet searches, and then went to synchronize it, as stated above, and also some 4-6 other versions of synchronization. None worked.

2. Found my second key fob. Encouraged with knowing that the second key fob worked fine, I went to unlock the Crossfire and nothing. I tested the second fob to see if that battery was working and it showed a light when pressed.

Would really appreciate some help on this one.
