Megane II Electronic Key Card Credit card-sized insert with/without 'Hands-Free'entry. Internal micro-switch failure, split solder on the coil, dead battery. Megane III Remote Key Card/ Push-to-Start Rectangular card with incorporated physical emergency key. Battery deficiency, real estate damage, internal moisture. Megane IV Modern Hands-Free Smart Card Streamlined, curved card with proximity opening sensing units. Battery wear, signal interference , software application desynchronization. Typical Signs of a Failing Megane Key Fob Before taking a screwdriver to the remote, it helps to identify why it is failing. Motorists should look out for the following indication: Intermittent Operation: The car locks or unlocks just after pressing the button numerous times or standing abnormally close to the car.
