Phaeton does not open does not start

Hello I have a huge problem. I drove with my fat guy to work today about 30km, put off just at 20:00 again the car did not react to my key. Thought ok maybe battery all of the key. Close by hand on alarm system goes off. Plug key in Alarm goes from car Starts not key small in the middle of the display. Left turn around right car does not start. ADAC called the battery measured each 11, and more.. stuck out nothing happens..intermediately error message system error workshop…in the meantime refuses to spit out the key.. then red error message key error.. it had rained..presumably Kessey control unit what do you think? Problem is I’m standing in Potsdam in the parking garage ADAC probably has problems getting me out of there without further trouble. I just want to bring me to the nearest VW workshop… since I am going to be loosely 1000€ or what do you think? Am totally desperate…
