Can anyone tell me the real value of skeleton keys? They seem to useless. I have been playing this game for 5 months now and have accumulated 26k plus keys but they appear to serve no purpose. They claim to be necesay to enter certain locations but  I am only seeing them required for the xmas school, hotel, laboratory, and emperor's palace. Not much value in exploring those locations now since there is little reward and the cost in energy is high so I do not go there. Why does the game keep churning out little needed rewards? What am I missing?
