I don't know about the Megane but with my Lag 11 the car has to read the card (and the only way it can do that is by putting it in the slot) before the immobilisor will switch off to allow the car to start. When the card is in the slot it is locked in until you stop the engine.
I am pretty sure that what you want to do is impossible even with the hands free card.
