A controller is provided. A digital valve, comprising a shaft configured to slide laterally between a first, unlocked position in which the shaft allows inward movement of the mechanical button and a second, locked position in which the shaft blocks the inward movement of the mechanical button. The electronic button, once actuated, is operable to cause the controller to direct the digital valve to move the shaft from the second, locked position into the first, unlocked position to unlock the mechanical button, and the mechanical button, once actuated, is operable to open the door when the shaft is in the first, unlocked position.
