Renault broke industry norms with the Megane II by dropping the standard key entirely in favor of a plastic card resembling a credit card (albeit thicker).

• Slot-in variation: The chauffeur inserts the card into a slot on the dashboard and presses a "Start/Stop" engine button.
• Hands-free variation: The car spots the card's proximity, allowing the doors to open automatically and the engine to start with a button press while the card stays in a pocket or bag.

• Flat Battery:When the remote functions quit working, the battery inside the key fob or card requires replacing.
• Desynchronization:Sometimes, the key loses its pairing with the car's computer system, needing a manual reprogramming sequence.

How to Replace a Megane Key Card Battery (Megane II, III, & & IV)

If your car displays a low battery warning, changing the coin cell battery (generally a CR2032 or CR2025) is easy:

1. Locate the release button or slide mechanism on the key card to extract the emergency metal key blade.
2. Utilizing the idea of the emergency key or a little flathead screwdriver, carefully pry open the plastic casing of the card.
3. Remove the old coin cell battery.
4. Insert the new battery with the positive (+) side facing downward (or as suggested by the maker markings).
