I have recently had a problem since didn't start the car (s320 w220) for a week. Did try to open it using manual key last time and used jumper.
The next two days battery dead again, this time can't open the boot. Even the key can't be turn to position 1.

Any suggestion. Please help.

Thanks.

 

might have to turn to the left and push the button in.

 

Chassis221 is correct.

Key is sufficiently large that it is not easy to turn the key and press the button in.... but it is mechanical and does not rely on the electrical assistance.

Putt the key in at 180degs to where you have it at present. This makes turning easier.

from under the hood, there is a battery terminal there for jumper.

do it from there. (remove the plastic cover with + )

 

Change the damn battery!!!!!

 

IF we are talking w220 you just use the manual key and press the button. PERIOD.
