540c flat battery / windows

[Dave_T1R]

Can someone please explain to me like a child how to avoid a broken window when I get power back into the car

2016 540c with a flat battery, windows completely shut

Will be following the procedure to use the key blade in the lock underneath / lever in wheel arch...

Thankyou, the windows are completely shut
