Masterkeying programs are too expensive, make your own!
Let me give you a few formulas to create your own pinning chart. But before that you should understand about progression sequences and such. I'm going to assume you as a locksmith know about this already.
Let's make a small MK system with only 4 change keys using Schlage.
If our MK is 256930 and we progress the last chamber then our change keys will be
CK1 256932
CK2 256934
CK3 256936
CK4 256938
To make your own pinning charts using excel I would use this formula.
MK 256932
CK 256934
BP - MIN (MK:CK)
MP - ABS (MK - CK)
TP - This formula will be explained later.
Our bottom pin formula is the MINIMUM OF THE MASTER KEY & CHANGE KEY NUMBERS only.
The master pin formula is the difference of the masterkey & change key, but by using ABSOLUTE VALUE OF THE DIFFERENCE, we don't get a negative number.
I hope some of you can understand this.... I will upload an excel file when I have time for those of you who need it.
It's really very simple to make pinning charts using a spread sheet.
Please don't waste your money on programs that to me are confusing as hell.
When you can learn to use simple formulas already built with Excel, your creative mind is your only limitation.
CLH!
