the key cards for the new shape lagunas are coded to the veicles chasis number once programed it is not possible to change the code, i have been to the renault dealers in my area, and to pivate garages that do renaults and have been told from early september renault will not any longer suply the codes even for new key cards to be programed, so be wary unless you have the knoledge to programe these yourself. regards mick.
