Security

Smart keys are advanced electronic keys that communicate with a vehicle through one of the antennas in the car to unlock the doors and start the engine.

This makes it much more difficult for thieves with a technological edge to spoof or intercept the signal and use the key to take your car.

They also come with the backup lock, which stops the vehicle from starting without the key.
