Security

Smart keys are computerized key fobs which communicate with the vehicle through an embedded antenna to unlock doors and start the motor. Smart key fobs, in contrast to conventional keys that emit the same frequency every time they're pressed, send encrypted signals that are compatible with the car to which they belong.
