This is a very common problem with Renault cars that use the card style key. When the card is inserted into the reader a message is displayed on the control screen saying insert card, or card not detected.
This usually means the key card is faulty and will need to be replaced. The problem is likely to be with the soldering joints inside the card. With constant use the internal working of the card bend and crack. In some cases they can be repaired by specialist Renault key card repairers, but in our experience the repair is only temporary and the card will most likely fail again.
