Security

Smart keys are highly sophisticated computerized key fobs that communicate with a vehicle via one of the car's embedded antennas to unlock the doors and begin the engine. Smart key fobs, as opposed to traditional keys, which emit the same frequency each time they're used, transmit encrypted signals that are compatible with the specific car to which they belong. This makes it more difficult for thieves with the latest technology to impersonate or intercept the signal and use the key to take your car.
