The invention relates to a safety system (1) for a lift (2), containing at least one control unit which can be operated in at least two different operating modes. The safety system (1) also has at least one electronic lock (7) which is connected to the control unit and can be connected or is connected to at least one electronic key (8). The control unit is programmed or can be programmed in such a manner that, when there is a connection between the electronic key (7) and the electronic lock (8), the control unit can be operated only in an operating mode from a first subset of the operating modes and, when there is no connection between the electronic key (7) and the electronic lock (8), can be operated only in an operating mode from a second subset of the operating modes. In this case, a maintenance mode is available only in the second subset of the operating modes. A lift system having at least one lift (2) and at least one such safety system (1) and a method for operating such a safety system (1) are also disclosed.
