The last two-digit number to the door on the lower
level of the ship in the little bathroom after you
have unlocked the piano, is 00. So the total

Once you have deactivated the flag sequence in the
Executive Meeting room, there will be a memo and a
medallion. To get the Chimara symbol, go to the
boiler room. And then place it in the ship model
in Lin's room. Take the medallion back and then
head to the freezer room to get the unicorn
symbol. Take this medallion to the room with the
two doors leading to the outside pool. And there
you have the two keys needed to open the piano to
the lower level.
