Since modern-day Megane keys-- particularly the renowned key cards-- rely on a mix of fragile internal electronics and physical plastics, they are vulnerable to specific types of failure.

4. Transponder Desync/ Corruption
Often, the digital handshake between the key and the car's Body Control Module (BCM) fails. This can happen due to strong electro-magnetic interference, dead batteries, or damaged internal memory, resulting in a car that refuses to crank.
