whatsup guys 2003 a4 1.8 here

gonna start posting here more often.... anyway..is there a way to childproof only the pass rear door? i tried turning the key on the frame of the door, but i can't seem to get the rear drivers door to not be childproof... my kid is in a carseat on the pass side, so she won't be getting to the other door. its just kind of annoying when i have an adult behind me who cant get out.
