A door lock set includes: a housing fixed on a door; an upper cam rotatably mounted on an upper portion of the housing and operatively retracting an upper latch; a lower cam rotatably mounted on a lower portion of the housing and operatively retracting a lower latch; a first linking rod and a second linking rod juxtapositionally pivotally secured between the upper cam and the lower cam and respectively disposed on a left side and a right side of the two cams; whereby upon a clockwise rotation of either cam, each latch provided on a right side of the door will be retracted; while upon a counterclockwise rotation of the cam, the latch provided on a left side of the door will be retracted, thereby optionally satisfying any door latch regardless of its right side position or left side position.
