What is on the pillar of the car door lock?

[MacIsabelle]

It is the locking lever on the pillar of the car door lock. Here are the relevant details: 1. Introduction: Vehicles equipped with this feature have a chip embedded in the key. When starting the ignition, the anti-theft controller reads the key information via an antenna on the ignition switch. If the information is valid, it sends a command to the engine control unit (ECU) to allow the vehicle to start. When replacing the key, anti-theft controller, or engine ECU, an anti-theft matching procedure is required. 2. Additional Information: The engine immobilizer system can be supplemented with an additional anti-theft device, which serves as a deterrent. Additionally, the wiring method is crucial, especially the routing of the anti-theft alarm horn's wires, as the first step a thief takes to bypass the anti-theft system is to cut the horn's wires.
