ABSTRACT:
Prior latches for sliding doors typically lock only from the inside of the door. The present invention provides a lock and latch system which allows the sliding door to be locked using a key from inside or outside the door, allowing the home owner to prevent unauthorized access by the picking of the external lock or breaking of the glass door and releasing of the lock from the inside. This is accomplished by providing a lock and latch in which the latch hook is rotated either by an internal handle or an external key. A rotating lug member, which is rotated from the interior by a key, can be engaged to block rotation of the latch.
