The remote controlled deadbolt door locking system (the "unit") is designed to be an add-on safety mechanism for existing entry doors. The unit is designed to be mounted onto the bottom corner of a door, where in the engaged position, it prevents said door from being opened even if the main lock has been tampered with. The unit makes use of a small DC electric motor to move a steel shaft in the vertical direction into a steel bushing that is mounted into a drilled hole in the floor directly in front of the door and under the unit. The unit is mounted onto the door with four carriage bolts through the door, and a mounting plate from the outside of the door, through four matching holes in the unit itself. The unit is then simply tightened on with normal hex nuts. The unit is equipped with several safety circuits, which warn the user if any of the following occur: low battery or battery failure of either the main or backup batteries; the shaft does not fully engage upon dosing; and if both batteries fall to a low condition. There is a built in triple redundancy to eliminate the possibility of the homeowner locking him/herself out. The operation of the unit is accomplished through a two-button remote control, which can be attached to a key chain. In this way, the unit acts just like a simple dead bolt, but one that can be locked while the homeowner is standing outside of the house.
