X5 Door lock question.

[Rickjen]

I have an 06 X5 After killing my battery I was able to open the drivers door with the key but then realized that I could not open any other doors from the inside of the car. Obviously the unlock button wouldnt work since there is no power but the manual pull handles also didnt work. So the question is, say I am in the car with the doors locked and the battery dies or for some other reason all power is lost, am I stuck inside this thing? How is it that the door pulls do not unlock and open the door? In my Audi, if you pull the handle once, the door unlocks, pull it again and the door opens.
This seems like a potential very dangerous situation. Am I just missing something?

Thanks
