The Dead Battery Syndrome If the car stops working to open remotely or the "hands-free" feature quits working, the offender is typically a basic CR2032 or CR2016 lithium coin cell battery. Symptoms: Car does not respond to remote buttons, however the car still begins when the card is placed into the dash slot (on Megane II/III). 2. Broken Internal Solder Joints Renault key cards undergo constant pressure-- typically sitting in chauffeurs' back pockets. In time, the internal battery terminals, microchips, or antenna coils can experience tiny fractures where they are soldered to the circuit board. Symptoms: The card works periodically, or only when squeezed or twisted in a specific way. 3. Desynchronization In some cases, the key card loses its digital "handshake" with the automobile's Body Control Module (BCM). This can take place if the battery is left dead for too long or due to strong magnetic interference. Signs: The red immobilizer light on the dashboard flashes rapidly, and the ignition refuses to engage despite the doors opening.
