Water Damage

If the key fob has failed to work one day in the middle of the night or after trying every option at home to fix it e.g. replacing the battery, reprogramming, and using the spare key fob, you might have a defective receiver module on your 500. The receiver module is located under the dash and picks up the radio frequency signals from the key fob. It transforms the signals into electronic commands that are then read by the vehicle.
