So I have an assortment of Primus blanks, both standard and control. In addition to the standard Primus keyblank part number, 35-157 (standard) or 35-158 (control), each has a four-digit code:
1001
1003
1004
1006
It seems obvious that 1001 is the standard-issue Level 1 sidebar. (I could, however, be entirely mistaken.)
Would it follow that 1003 would correspond to Level 3, 1004 to Level 4, and so on? Or are each of these codes simply variations on Level 1? Or would that make them Level 1+? Or is there another explanation entirely?
I imagine Evan will want to demonstrate his expansive knowledge of the intricacies of Primus sidebar coding, and ... wow, I'm actually looking forward to it. Might anyone else care to weigh in? Would it help if I posted photos of the side bit-milling associated with each code?
