A locking system for security door or window includes a metal frame secured onto a house around the door or window. A lock is disposed in the metal frame and has a movable locking member that is movable between a locked position in engagement with a stationary locking member in the door or window when in a closed position in the frame and an unlocked position. A manually-actuated member extends through the metal frame and a hole in the door or window frame and includes an operating member inside the house and also within a guard secured onto the inside of the door or window frame enabling the operating member to be operated through an opening in the guard that opens away from the door or window opening to manually operate the lock from inside the house and prevents anyone from gaining access to the operating member.
