When a motorist attempts to begin the vehicle, the Engine Control Unit (ECU) sends out an electronic signal to the key. The chip in the key gets this signal and responds with a special digital code. If the code matches what is kept in the ECU's memory, the immobilizer is shut down, and the engine starts. If the codes do not match-- or if the chip is missing-- the car will stay immobile, even if the physical blade of the key turns the ignition.

The Step-by-Step Procedure:Diagnostic Connection: The specialist connects a diagnostic programming tool to the OBD-II port, typically found under the control panel.Accessing the Immobilizer System: The technician browses the software to access the automobile's security or immobilizer module.Security Clearance: Many modern-day vehicles require a "Pin Code" or "Seed Code" to access to the programming menu.
