PURPOSE: A jig for a key process is provided to quickly and simply process the duplication of a key while exactly duplicating the key. CONSTITUTION: The jig for processing is formed with a key inserting hole(4) and an opening unit(5), forming a groove unit(2) and a projection unit(3) in alternation on the left and the right parts of the upper part of the opening unit. Herein, the interval between the groove unit and the projection unit is set up based on the kind of the key. When processing the key, the material(12) of the key is inserted into the opening unit(4), and the duplicated key is manufactured by taking out the material of the key and after-processing the height of the peak after a groove is formed by processing the part of the groove unit with a file(6).
