Will car start if key fob battery is dead?

Yes, a car can still start even if the key fob battery is dead, as long as the vehicle has a traditional key slot or a backup starting method. Many modern cars allow you to start the engine by pressing the key fob against the start button or a designated area in the vehicle. However, if your car relies solely on the keyless entry system, you may need to replace the battery in the fob to unlock and start the vehicle.
