Hi there it is possable that both cards are faulty on the central locking operation and ok on the starting function , the best way is to take it to the renault dealer and see if they might give a contribution towards a new key if they say it is faulty, and they will say how much they are willing to pay , due to the fact it is a 05 plate and its only just out of its warrenty ,hope this helps .
