The door to the Mirror room doesn't have a "You need a key symbol." It's just a door with a star on it. Defeat Bowser in "Bowser in the fire sea" and unlock the middle door on the second floor of the castle's main room. You will then enter a room with stairs that go in a circle. Go through that room and go through the door on the other side. Now you will be in a circular room of courses. Once past the "circular stairway" there will be two doors with a star on it in the room on two sides of the circle. Find the star door with the red carpet and enter. You have now found the room with the mirrors.

to get to the mirror room you have to go through the door on the top floor of the castle. then you go in one of the doors with a star on it!!! :)
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.

Look in the mirror. Your reflection should change to Luigi. Defeat King Boo and Luigi is yours.
You have to unlock Luigi and then use his invisibility power to go through the mirror, if thats what you are asking.
