The method forges asymmetrical products such as an automobile door lock instead of machining in the conventional method, to make mass production and standardization possible. The forging method comprises a step of inserting cylindrical workpiece into a groove (1) of a first die (1), and pushing a first punch (3); a step of lifting a second punch (4) to the center line of the first die (1), and inserting the punched workpiece into the eccentric groove of the second punch (4) by pushing a pin (7) on the workpiece within the first die (1); a step of inserting the workpiece into an eccentric groove (10) formed within a second die (2).
