The Evolution of the Renault Laguna Keycard
Introduced in the early 2000s for the Laguna II generation, Renault's credit-card-sized entry and ignition system was a significant departure from conventional physical secrets.

- Overall Unresponsiveness: The vehicle stops working to acknowledge the card entirely, resulting in a "Card Not Detected" message on the control panel.
- Physical Damage: The plastic casing is broken, separating the internal circuit board from the external shell.
- Central Locking Failure: The distance or remote buttons on the card no longer operate, however the car starts when the card is placed into the dash slot.
