fuel / ecu issue renault megane 1.4?

Ive recently brought a renault megane 2003 1.4 petrol, the display was saying fuel / ecu issue.. I found a donor car on a 05 reg so got the fuel pump module, ecu, black box under glove box, card reader and replacement card form donor vehicle as i was told this would sort issue out without having to get it reprogrammed by renault!! have changed all parts but the card want lock or un-lock doors, and when insert card into reader nothing happens apart from display clock illuminates then drivers display says remove card..
can anyone help!!
many thanks
