An elevator system (20), comprises an elevator car (22), an elevator controller (40), configured to control operation of the elevator car (22), a safety controller (52) and a plurality of safety contacts connected to the safety controller (52), wherein the plurality of safety contacts monitor the elevator system (20). The safety controller (52) is configured to receive individual status information from each of the plurality of safety contacts and to prevent movement of the elevator car (22) when the individual status information received from one of the plurality of safety contacts indicates an unsafe condition of the elevator system (20). The safety controller (52) is configured to connect to a remote computing device, to receive first authentication information (500) from the remote computing device, and to authenticate the remote computing device if the first authentication information (500) meets an authentication condition. If the remote computing device is authenticated, to permit the remote computing device to override the safety controller (52) to enable movement of the elevator car (22).
