A2 Calculator

This A2 Calculator will not only show you how to pin your A2 6 and 7 pin cylinders, it will also show you if there is an error or errors in your chosen Control, Master, or Change keys. By showing you what the error is, you can then correct your key cuts or information. Simply press the "error reset" button (orange button) and the program will erase any and all errors that were in your key choices all you have to do is simply re-input your corrected key cuts and press the GO button again. If there are no errors you may proceed to pin your cylinder up! This calculator will continue to check for errors each time you press the GO button. An error would be a 1 cut in either the master or buildup pin lines. The reason is is that there are no 1 master pins in an A2 Pin Kit.
