i have a 54 plate scenic which i think has a flat battery, i am unable to open any doors as it is a key card control. i can not open the bonnet as i can not get into the car.
There is a metal key that pulls out of the card. On the front passenger door handle you will find a small plastic cover with a picture of a key on it. Slide this back to reveal the slot where you insert the metal key. Push the key in and turn it and bingo ..... this will unlock the door.
