Battery Flat Locked out E46 Touring

Before I get redirected I have searched high and low for an answer to my question.
I have a 320d 'TOURING'. My key battery is fine but my car battery has gone flat.
My lock has broken so without power in the car my doors wont open with the remote and I am locked out.
Is there any way of charging my battery without being able to get under the hood / Bonnet.
There is no key hole in the touring tailgate so the only keyhole is the drivers door which has broken.
Any ideas other than brick through window would be hugely appreciated.
In desperation!!!

Ah, yes, the Touring is a DIFFERENT animal for dead battery/lock outs!!!!!!!!!!!

You my friend have a "Special" case on your hands!!

With a broken driver door lock link, I will need to think about this for a while.

Almost seems like you will need to jack up the front of the car and attempt to find the starter connection and get a charger hooked up. I will try to think of another way you may be able to connect up power to either charge or power the car up. Also not sure what can be done to pop the hood from the grille area. Not sure if you can break out a grille kidney to pop the hood?

I would not brick a window, I would probably drill the drivers door lock cylinder out before taking a window out.

At least in the US a replacement drivers door lock cylinder is around $75 already keyed with the rear link attached that is broken. An you can drive your car and not have to worry about being without a window while you wait for the driver door lock cylinder.

I can think of two ways to potentially access the positive terminal from the exterior:
1) Under the car, starter motor area. There should be a cable directly from the battery. Requires raising the car of course
2) Rear trunk breather removal to access the battery itself. Requires removal of right rear wheel, rear bumper cover and then I believe (I'm not certain) the rectangular breather/vent can be pushed in and away to access the positive battery terminal.

Edit: ^#2 above, I do not have any knowledge if this applies to your touring. Best bet is starter area.

Thanks for the suggestions, I have jacked the front of the car up as much as I can but can't get to the starter. I've got a mirror but still cant see.
I have a friend coming round later with a bigger trolley jack so hopefully may make some progress that way. Do you know if you have to remove covers etc or should I just be able to see the starter?
I saw in one post to try connecting to the horn as it has a permanent power feed? Not sure bout that one just yet?
jf, I read its a real pig to pop the hood through the front as once you remove the kidney (which breaks the clips) there is more plastic to cut behind before you can even start on the impossible to reach fittings. I may be wrong?
jb, the breather may be a possibility but I cant get the wheel off as the locking wheel nut adapters are in the car so cant remove the wheels!
I'll keep you posted just in case this becomes useful for anyone else
As above, much appreciated.

Bigger Jack was the answer, got it up high, removed larger cover from underside near the front and found big red wire.

Attached charger, pressed key and hey presto I was in.

First job... fix the door lock link!!!

Thanks for the assistance and I hope this is of some help to others.
