A door locking system is disclosed for integrating into an entry door having a door hardware extension therein and a door sill. The door locking system includes a continuous cane rod that transitions from an open configuration to a locked configuration by radial displacement of a handle of the continuous cane rod away from an upper retention member, vertical displacement of a shaft of the continuous cane rod such that a heel penetrates a receiving member, and radial displacement of the handle of the continuous cane rod to a lower retention member such that the handle is releasably retained by the lower retention member. The continuous cane rod transitions from the locked to the open configuration in the opposite manner. The door locking system provides a reinforced entry door in the locked configuration.
