2004 Audi A8 - Jump Locations or Charge or Trunk Release?

Need some expert advice here.

I have a 2004 Audi A8 in which the key is stuck in a broken ignition. I cant release the key with the little button on the ignition switch as the ignition switch cylinder is spinning. There is also no power to the car at all and I cant access the trunk as the key is stuck in the ignition and wont come out.

I looked under the hood and cant find any jump locations where I can feed the car power so i can open the trunk.

Can someone help me here? I dont think there are jump locations on a 2004 A8 as this was a flaw in design. But how to get I get power to the car, or even some power just to get the trunk open so I can put a new batter and jump the car etc to get the key out?
