Driver 8,4,7,9,12,5
Control 6,14,12,12,6,10
Master 6,4,4,2,4,2
Bottom 3,1,0,0,1,6
Total 23,23,23,23,23,23.
Since the core was combinated to the BEST standard, so the rule of 13 worked to produce a properly operating control key of 8,1,4,6,9,5.
Now here's where the confusion comes in, I was under the impression that if the bottom pins and the master pins where added together the resultant would produce a control key code, in this case that code being 9,5,4,2,5,8, but the key I cut will not operate the core, so either I cut it incorrectly or there is something awash in my thinking.
At this point I am stuck as I ran out of blanks to experiment with as I stupidly cut 4 blanks bow to tip before thinking to me self "hey dummy BEST is cut tip to bow," so with some down time waiting for more blanks to arrive I figured I would toss this out and see what gets tossed back at me.
BTW this is of course an A2 system.
