The battery in my 2014 Challenger SXT went dead from sitting for a few days. So I replaced the battery in the car but now none of the buttons on the key fob work. I replaced the battery in the key fob and still nothing . Panic, door lock/unlock does not work on either fob. But I can start the car with the fob in my pocket. I just cannot figure out what would have caused the fob to not work just by replacing the car battery. Any info would be appreciated. I hope I don’t have to go to a dealer and get screwed with high prices.
