An apparatus for monitoring operation of a locking mechanism applied for securing an elevator door to a closed position is provided, where said monitoring is carried out via monitoring operation of a door driving system arranged for driving movement of the elevator door between the closed position and an open position. The apparatus is arranged to: receive one or more parameters that are descriptive of movement of the elevator door from the closed position towards the open position; determine, based on said one or more parameters, a door movement profile that is descriptive of an aspect of movement of the elevator door in relation to the closed position of the elevator door; and detect compromised operation of the locking mechanism based on one or more characteristics of the door movement profile within a portion thereof that represents a predefined traveling distance in relation to the closed position of the elevator door.
