I've got a 2017 Charger with a factory remote start. So, I have 2 key fobs. One is the primary and the second is a back up. Neither fob works for the remote start, nor do they unlock or lock my car. I noticed this about a month or so ago. I doubt both batteries are bad, but I guess it is possible. But, my question is if neither of the fobs are bad does something need to be reprogrammed in my car? I probably should just go to the dealership but out of sheer laziness at the moment I am here. Thank you!
