Why is there no response when inserting the car key?
1 Answers
The reasons for no response when inserting the car key are: 1. The power cord is detached or has poor contact at the battery socket; 2. The converter is damaged. The basic principle of a car key is: a weak radio wave is emitted from the owner, received by the car antenna, and after the electronic control unit (ECU) identifies the signal code, the system's actuator performs the action of locking or unlocking. Car keys utilize the wireless remote control function of the central locking system, allowing doors to be opened or locked from a distance without inserting the key into the keyhole. They are categorized by usage into: 1. Active working mode; 2. Passive working mode; 3. Coil induction mode.
