Go into the Pokemon Mansion and head up the stairs at the end of the red carpet.

From here go up the second staircase at the top of second floor.

On the third floor activate the Mewtwo switch and jump off the left ledge a bit to the south. When you land go down the staircase.

Now from the basement head into the little room with a Mewtwo statue and a trainer in it. Activate the statue. Now go back to the staircase and go up the northern hallway.

Up the hallway you will find another statue, activate it to gain acces to a room nearby containing the secret key item to unlock the gym.
