I found the hole near the Library building and the detention zone. There is a door and a keypad here. I used the keypad and my character guessed the code, but it won't open. Do I need a key? I also tried some weapons to see it would fall down, but that didn't work either.

That particular door is used late in the game during Chapter IV

during the mission Stronghold Assault where Jimmy is tasked with attacking the nerd's "stronghold", the observatory to confront the nerd's leader Earnest.

You are however able to leave the campus officially after you complete chapter I where they open the gates to the front of the school.
