Just wandering how you are suppose to open the door on a C6 if the battery dies ? I dont see no place for a key to go. There is a green knob connected to the battery in my wifes 08 C6 that when you turn it it disconnects the power to the battery. Well today it turned by itself and she couldnt get the door opened, she didnt know about the pull lever on the floor, so she took the sunroof out and climbed out of the car. In order for me to open the hood i had to climb back into the car throught the sunroof. which is why im wondering how you open the door if there is no power. Thanks
