To start a keyless car with a dead battery, hold the key fob close to the start button or in the designated spot in the vehicle. Most cars have a backup system that allows the key fob to transmit a signal using a passive RFID chip. Press the start button while holding the fob in place. If this does not work, you may need to replace the key fob battery or use a traditional car key hidden inside the fob.
