2. Broken Internal Solder Joints

Renault key cards go through constant pressure-- frequently being in motorists' back pockets. With time, the internal battery terminals, microchips, or antenna coils can experience microscopic fractures where they are soldered to the circuit board.

3. Desynchronization

Sometimes, the key card loses its digital "handshake" with the car's Body Control Module (BCM). This can happen if the battery is left dead for too long or due to strong magnetic interference.
