On some BMs you can open the door of a car with a flat battery by turning the key and lifting the door handle at the same time. Might need a few attempts to get the motions in sync though.
This ^^

My E65 had a battery drain issue until I unplugged the comfort access handles; the lock would allow me to open the boot & the drivers door to open the bonnet etc

Might need to spray the locks with some WD40 to clean any grime out first though and then turn the key as much as you can to 90º etc
Heard this one before, doesn't work, the lock barrels turn only a handful of degrees before hitting the deadlocks.

Owner's manual for a 2005 E65 downloaded from https://www.bmwsections.com/docs/7series/ sez:

If an electrical defect occurs, you can unlock or lock the driver's door with the key in the end positions of the door lock.

Insert the key in the luggage compartment lid's lock and turn it all the way to the right – the lid opens.

I'll guess the keys have rarely, if ever, been used in this mode so some lubrication might be required. In the case of the door lock the force required will be considerable as you're mechanically undoing the deadbolts. This all presupposes the locks and keys match!

Just went and tried this on my 2005 E53 X5 - turning the drivers door key clockwise did the trick.

Good luck.

Thanks. I'll wait for warmer weather and apply WD40. The key and barrels do match, I know that much.

They will turn more and unlock the car; as said, my 06 E65 had issues and the battery dropped to 2v one time... Still got in the boot & drivers side via the key

Clean the locks with WD40, work them loose and reapply lithium grease if you can
