Many residential doors feature hollow core construction and poor locks. They are easily forced or kicked open. If you desire additional protection, you need solid doors and quality locks.
Many burglars enter homes through poorly protected arcadia doors.
Additional locks and security measures here will prevent the door from being opened or lifted out of the track. Screws installed in the track above the sliding door frame will prevent the door from being lifted out of the track. Drill a pilot hole in the top track above, and slightly in, from each corner of the sliding door frame section and install a screw into each hole. Adjust the screws so that the head of the screw just barely clears the frame when it is moved back and forth. These doors need solid security as they are easily jimmied or forced open.
