An actuator mechanism for a door latch is provided. The actuator mechanism may include a first actuator and a second actuator. The first actuator can be pivotably coupled to a first support structure about a first axis. Moreover, the first actuator can include an engaging tip, a first engagement and a second engagement. The second actuator can be pivotably coupled to a second support structure about a second axis. In response to the movement of the arm of the second actuator about the second axis, the first engagement of the first actuator can rotate about the first axis to move the engaging tip to release the door latch. Alternatively, in response to the movement of the second engagement of the first actuator, the second engagement of the first actuator can rotate about the first axis to move the engaging tip to release the door latch.
