Q: Having a hard time starting the vehicle, would the key fob cause this? Car battery not dead, starts sometimes. 2002 Mercedes S430

asked by on

The vehicle will not start all the time. At first I thought it was the steering wheel was locked but that doesn't seem to be the case. I think it's the key fob. The vehicle's battery is not dead so it's not that. Would it be that I need a new key fob? If so, How much for the fob and how much for the programming?
