Because contemporary Megane keys-- especially the renowned key cards-- rely on a mix of delicate internal electronics and physical plastics, they are prone to particular types of failure.

This is the most common and easiest concern to repair. If the car fails to open from another location, or if the dashboard shows a "Card Not Detected" warning while trying to begin the engine, a dead coin-cell battery is normally the offender.
