If you mean the mirror room where you unlock Luigi (in Big Boo's Haunt) when you fall to the room, just go forward and touch the mirror with Mario, then wait. You'll have to battle King Boo to unlock him.
You have to unlock Luigi and then use his invisibility power to go through the mirror, if thats what you are asking.
You get luigi and you get the flower on the pillar and then you exit the reflection of the door in the mirror
there is no mirror key. using luigi go to the mirror room, grab a power flower, and you can go thru the mirror no u cant it doesnt work
If you mean on Super Mario 64 DS, then Luigi is in a painting in a haunted mansion & Wario is in a painting on the other side of the mirror in the mirror room. First get Luigi so you can get Wario.
You have to enter the room as Luigi. The flowers don't appear for Mario or Yoshi.
Look in the mirror. Your reflection should change to Luigi. Defeat King Boo and Luigi is yours.
You go into the mirror room as luigi then get the flower so you are invisible.Walk into the mirror then the picture of luigi on the other side would be wario inside.Jump into that and beat the boss.
