I have 2 Swift 5000 elevators that will not access from the hall key if they have been previously switched to car-top inspection. For example, if you turn your key from normal to in-car inspection the hall access key works fine at the terminal landings. However, if you switch to car-top inspection and run down on car-top then back to the top when you come off of car-top inspection the hall access key no longer works. Has anyone had this issue before?
