If the car fails to open remotely, or if the control panel shows a "Card Not Detected" cautioning while trying to start the engine, a dead coin-cell battery is generally the culprit. 2. Broken Microswitches Inside the key card, tiny electronic switches represent the lock, unlock, and boot buttons. Over years of clicking, these microswitches can separate from the circuit board or break totally, rendering the buttons unresponsive even if the battery is brand name brand-new. 3. Physical Cracks and Bent Casings Megane key cards are regularly kept in back pockets. Sitting on a tough key card can crack the external plastic shell or, even worse, snap the internal ferrite coil antenna utilized to interact with the car's immobilizer. 4. Transponder Desync/ Corruption In some cases, the digital handshake in between the key and the car's Body Control Module (BCM) fails. This can occur due to strong electromagnetic disturbance, dead batteries, or corrupted internal memory, resulting in a car that declines to crank.
