2. Broken Internal Solder Joints

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

• Symptoms: The card works intermittently, or only when squeezed or twisted in a specific way.

3. Desynchronization

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