Mitsubishi Service & Passenger Elevators @ Four Seasons Residential, SF CA

OK so I go into the service area and one of the three elevators went up. It was the service elevator to the residence part of the hotel. By some fluke the lockout failed and it let me go all the way to the top. At the top floor the lockout fixed itself and I couldn't go back down. I thought I was trapped for a while but I was able to exit that room on the top floor and go down on the passenger elevators.
