Abstract: What has been developed is a keyless door lock that prevents young children from opening doors their parents or caretakers do not wish them to open. The lock is a bolting mechanism type lock or a latching type lock having no keyed lock access side to it, but rather, a means for locking and unlocking the lock, such as a knob, on one or both sides of the door that when turned, unlocks the door. The lock is positioned within the door at a height that is unreachable by small children. The lock is useful for locking doors internal to the home (e.g., doors to medicine closets, cleaning supply closets, garage doors, doors at the top of stairs) as well as doors that provide access to the exterior of the home and therefore access to leave the premises of the home without supervision. Adults and older children, however, are never locked in or out of the room or house as no key is required for operating the lock, merely the turning of a knob.
