Stamp "G" on the blade. The 80-bit chips used to make the transponders here can be used from common 80-bit chips with a few pages changed and written. It is not smart to use the more valuable Ford 80-bit chips with this key, even though they will work just fine. (Need specific programming instructions). To generate a Subaru "G" chip: Read out generic 80 bit chip with iKeyClone Change pg 1 to "17" then click on lightning bolt next to pg 1 Change pg 30 to "06 08" then click on lightning bolt next to pg 30 Now check that it is correct by clicking on the "read transponder" button and read the whole chip out to make sure pg 1 = 17 and pg 30 = 06 08.  Done!!
