An electronic device includes a housing defining an interior space with an opening, a lid, a first locking member, a restricting member, and a second locking member. The lid is coupled to the housing to close and unclose the opening. The first locking member is coupled to the lid and movable in a first direction between a closed position to lock the lid over the opening and an open position to unlock the lid from over the opening. The restricting member is mounted to the lid and movable between a restricting position to prevent the first locking member from moving to the open position and a retracted position to permit the first locking member to move to the open position. The second locking member is coupled to the lid and movable in the first direction to allow the restricting member to switch between the restricting position and the retracted position.
