The car's receiver confirms that the transmitter is who it claims to be by using an authentication and encryption procedure. If it is authorized, the onboard computer unlocks the vehicle and starts the engine.

There are concerns that a skilled criminal could intercept the code transmitted between the key fob and the car.
