Extended data:
This intelligent key can emit infrared signals, which can not only open one or two doors, suitcases and fuel filler caps, but also operate windows and skylights. A more advanced intelligent key is like a credit card. When the driver touches the door handle, the central locking control system starts to work and sends out a wireless inquiry signal. When the intelligent key card responds correctly, the car lock will automatically open. The engine will only start when the central processor senses that the key is stuck in the car.
The system adopts RFID (Radio Frequency Identification) technology. Under normal circumstances, when the owner is close to the vehicle within a distance of about one meter, the door lock will automatically open and lift the anti-theft; When leaving the vehicle, the door lock will automatically lock and enter the anti-theft state. When the owner enters the car, the in-car detection system will immediately identify the smart card. At this time, you can start the car normally by gently pressing the start button (or knob), and you don't need to take out the car keys all the time.
