Help please! 2000 clk430 dead battery trunk won't open

Hi everyone,
I am new to the benzworld so forgive me if im doing this wrong. I have a 2000 clk 430 with a dead battery and i cannot open the trunk. I've tried the key and it turns360 degrees with no results. My fob and counsole buttons dont work. Also my radio wont turn on and power locks dont work. Ive jumped it and can start the car but trunk still wont open. I drove 60 miles and still not enough charge to open trunk??? I dont want to drill holes in my car so Any advice would be appreciated.

Thanks
