Renault Megane 1.6 16V Dynamique - Key Card

Howdy peeps,

Just wondered if anyone had knowledge about the electrics in Renault Megane 1.6 16V Dynamique? Reason being the Key card reader stop working, so it has been replaced with a tested/working item. The reader accepts the card, though the car won’t start (i.e. immobilised/engine not turning over. Now if the card would have been replaced, then I’d understand (i.e. would need resetting/pairing with the ECU). Problem is it’s my Missus car and now stranded outside my house on the main road, so I cannot even take it to garage. Can anyone shed some light or knows how to bypass the silly fecking key card.

Cheers folks.

this may help, if its the card at fault....?
