Help finding secrets

[BroChadman]

Does anyone know how to find out what the 6 button combination is for the dungeon?

And does anyone know where the key is for the potions room?

You can find paper with code combination on the table in office behind the big classroom.
Trader in greenhat dorms sells potion key, but you can find vent leads to that room, no need key.
