Deadlocked E60 - Potential dead battery?

[Odhran]

A family member's post LCI e60 530d is locked and won't open with either the use of both key fobs or enclosed key. When he tried to open it with the enclosed key it set off the alarm, but nothing else. I suspect the battery is flat, perhaps jumpstarting would solve the issue, but to do that, we need access to the bonnet. Any ideas how to get out of this predicament? A quick google seems to reveal it was common on the e39 but not much in the way of help for an e60. A

Many thanks

Can you get into the boot mate?

There is usually a procedure to deactivate the deadlock on the front passenger door (assuming a RHD vehicle) that's explained in the handbook if an E6x owner has theirs handy.

Insert the blade key, turn it as far as it will go anti-clockwise, lift the door handle, hold it up whilst turning the key clockwise, you'll find it goes further around than the normal 3 o' clock position - works on older generation BMWs and I assume newer ones also have just such a contingency measure for just this eventuality.

I'd try that above, the turn, lift, turn thing.
