I have beaten Bowser twice, I have all the characters, 38 stars, the second floor unlocked, but I have no place to put the second key. Where do you use it?

If you have all the characters, then you've already used that second key. But I'll tell you anyway.When you enter the castle, go up the stairs right in front of you and the key goes in that door.
Bust up Bowser and use the key on the door up the stairs in the first room of the castle. The first one to left of the first "big star door", if you know what I mean.
You use it on the door with a keyhole up the stairs in the main hall.
