Hi, I am new to this forum. I have a 2005 Crossfire with 2 keys that came with the car when I purchased it new in 2005. The key fob I always use works fine, my extra key fob is not working (car will not unlock and I am standing next to car trying). The last time I used it was about 6 mos. ago. I have read many posts here but still have some questions. Is there a battery in the fob? If so hw do you get to it and where can I buy the battery? I will try to program the fob again the way it is talked about on another post (put key in ignition, hit unlock twice, car should start) but can't do it now, I am at work. I just spoke with my Chrysler service advisor and he does not know if there is a battery in the fob and also said I would need to get a new fob from the factory. Also, I have seen posts that state the fob won't work but they open the door with the key - how do you do that? Your comments and suggestions would be appreciated. I really don't want to have to buy another fob - I think they are about $150
