A door locking system for precluding the picking of a lock comprises a door. The door has an outside, an inside and a facing surface. A bolt is mounted in the door. The bolt is adapted to slide between an unlocked orientation and a locked orientation. The bolt is formed to include a linear surface with gear teeth constituting a rack. A handle housing is mounted on the door. The handle housing has a handle. The handle has a handle shaft rotatable with the handle and coaxial therewith. A pinion gear is coupled to the handle shaft and formed with peripheral gear teeth in meshing engagement with the teeth of the rack. An operator controlled locking member is provided. The locking member is slidably coupled with respect to the handle shaft on the inside of the door to optionally lock and unlock the door and to preclude picking the lock.
