Many residential doors feature hollow-core construction and poor locks, which are easily forced or kicked open. For additional protection, you need solid core doors and quality locks.
Many burglars enter homes through improperly secured arcadia doors.
Additional locks and security measures 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 doorframe 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.
