• Total Unresponsiveness: Neither the lock, unlock, nor boot release buttons work, and the car stops working to recognize the card in the dash slot.
• "Card Not Detected" Warning: The control panel displays a mistake message even when the card is inserted into the reader.

Step 3: Reprogramming and Synchronization

Often, a Megane key fob fails to work merely because it has actually lost synchronization with the car's Body Control Module (BCM). This often takes place if the battery has been dead for a prolonged duration.
