Security

Smart keys are sophisticated key fobs with computers that communicate with a vehicle through one of the antennas that are embedded in the vehicle to unlock the doors and begin the engine. Smart key fobs, in contrast to traditional keys, which emit the same frequency each time they're pressed, transmit encrypted signals that are only compatible with the car to which they belong.
