When the key is inserted into the ignition or the “Start” button is pressed, the vehicle sends out an electronic burst to the key. The transponder chip reacts by sending out an unique alphanumeric code back to the ECU. If the code matches the series stored in the lorry’s memory, the immobilizer is shut off, and the engine begins. If the codes do not match, the fuel pump and ignition system remain disabled.

The programming tool advises the ECU to accept the new transponder code.Testing: The professional validates that the remote functions (lock/unlock) work which the transponder effectively bypasses the immobilizer to begin the engine.Comparison: Professional Services vs. DIY
