HELP!!! i am stuck! the only areas i cant get into are the keypad room in the attic, the master bedroom, and the pool room. i have the key head but i cannot find the handle and i cannot figure out how to use the keypad in the attic any hints??

For the keypad password, you have to go to the art gallery first.
Get the dining room painting and if you look around afterwards, you'll find the password...

right in front of me the whole time! thanks!
