Vehicle Smart Key Technology

Security

Smart keys are computerized key fobs that communicate with the vehicle via an embedded antenna to unlock doors and start the motor.

For example, if you switch on the car while holding the key fob in your hands, the windows and sunroof will open to let air circulate through the cabin.
