1 Answers
The reasons why the car key cannot be inserted are: 1. There is debris or blockage in the keyhole; 2. The lock has been pried or damaged; 3. The car key is deformed; 4. The steering wheel is locked. The car key utilizes the wireless remote control function of the central locking system, allowing doors to be opened or locked remotely without inserting the key into the keyhole. The basic principle of the 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 are categorized by usage into: 1. Active working mode; 2. Passive working mode; 3. Coil induction mode.
