To use the mystery time key go up to the second floor in the dorm and to the large elevator-like door, hit A, and select 'Mystery Time'. This only works if you have a key from Principal Sol. If you have a key you can see a small picture of a key next to the ritch in your inventory.
Does this answer your question?
