Used in the automotive field, the chip is known as a magnetically coupled forwarding system. The magnetically coupled forwarding system is passive in nature, and the chip itself does not need a constant power supply, so it does not need to be powered on at all times. The role of the car key chip: When the car key is turned on in the ignition switch, the engine control unit on the car will send a set of encrypted electronic code signals to the chip in the car key, and only when the car ECU unit can read the feedback and receive the correct anti-theft code signal will allow the car to start.
Connect the matching instrument with the key anti-theft circuit board interface;
2, select the car brand and model on the matching instrument, enter the system;
3, enter the anti-theft system to match the key
