PowerKeyOne is a simple, easy to use master keying program that generates bitting lists in the Standard Progression Format (SPF). While the program was designed for use by locksmiths who are familiar with master keying, it can also be used effectively by the beginner.
It does produce the SPF with a few extra features. In addition to the standard one or two step progression used in most brands, it allows you to select one, two or three step increments. There is also an additional increment specification that lets you mix one, two or three increments within the same key system. It allows those features for cylinders with 4, 5, 6, 7, 8, 9 or 10 chambers.
It can print a bitting list to a printer or to a PDF and it can do that with or without pinning. All combinations that are a MACS violation or break some other rule for a specific brand have the color of their background changed from white to red for easy identification. It can print a single page, a range of pages or all pages.
PowerKeyOne designs systems for standard cylinders, but no IC models. It will run on all Windows machines from XP to Windows 8.
