Many residential doors are of wood hollow-core construction and have poor locks. They are easily forced or kicked open. If you want better protection, you need to install solid doors and quality locks. For maximum protection, use metal doors. Do not use doors with glass panels.
Many burglars enter homes through poorly protected sliding glass 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. Auxilliary patio door locks may also be purchased and install easily.
