I have read the owner's manual cover to cover and the issue is not even addressed, as far as I can see. Ironically, it does talk about the fact that you cannot turn the ignition key from the "lock" position if the battery is dead (6-8). They didn't mention how you got into the car in the first place to try and turn the key
I guess you're going to have to be extra cautious about the car battery and the intelligent key battery.
Good luck
