3. Desynchronization: Occasionally, the card loses its sync with the car’s computer due to strong electro-magnetic disturbance or a completely dead car battery.
4. Internal Chip Failure: The RFID transponder chip– responsible for the immobiliser handshake– can deteriorate or stop working in time, preventing the car from beginning even if the doors unlock.

3. Security Bypass: The tool interacts with the car’s Body Control Module or UCH to extract or bypass the security code. (On newer models, rolling security procedures need internet access to Renault’s safe servers).
4. Card Coding: The new card is put in the card slot or held near the start button. The diagnostic software application writes the lorry’s distinct transponder signature onto the card’s chip.
