Abstract: A child/pet-proofing apparatus and system is described. The apparatus is configured to facilitate the locking and unlocking of doors, cabinets, and drawers of a household while retaining the original aesthetic of the doors, cabinets, and drawers by employing the pre-existing hardware as a sophisticated manipulator of an internal locking mechanism disposed within a housing behind the face or front of the drawer or cabinet. The locking mechanism is configured to be locked and unlocked via two-step process which namely includes pushing the knob inwards and then turning the knob while it remains depressed. As the push-and-turn action is performed, an internal pocket spring is compressed, which enables the placement of locking pins into specifically arranged pin holes disposed on a drive disc. The drive disc is in communication with a lock arm which is then pivoted away from the junction of the drawer/cabinet and the surrounding cabinet housing.
