A secondary security garage door is provided that is attached to and operates behind a primary garage door. The security door is made up of multiple panels composed of an outside frame supporting a wire mesh material. The security door rides along a separate guide rail adjacent to the primary garage door guide rail When assembled and installed, these panels form a barrier that prevents unwanted intruders access to the garage, or the escape of pets. This also allows for the free flow of outside air into the garage, thereby solving the problem of overheated garages during the warmer seasons. The secondary security door is provided with an interlocking system. This system allows both doors to automatically be locked together and ride up and down the rails in tandem. This feature allows the door operator to lift the security door by closing the primary door, which will then engage the interlocking system, thus, allowing the doors to move together. Thus the user will not have to manually lift or lower the security door if the primary door is equipped with a power garage door opener. In order to utilize the security door, the user will simply lower both doors, disengage the interlocking system and then raise the primary door. The security door is constructed from panels which are sized to fit a single car width garage door opening. The panels can be connected end to end to double their length and span a two car garage door opening.
