Perfect Master creates complex master key systems by answering just 3 simple questions.

Look at the Main Menu screen below to see all the options, we will only explain a few of them.

Let's create a master key system for 6 pin Arrow. Start Perfect Master and click "Create New System."

Specs for 56 lock types are listed or you can create your own specs. Click on the entry for Arrow.

When you click on Arrow you'll see the screen shown below.

Change the lock specs (Short Pin, Long Pin, etc.) if you want to or just enter the System Data and Client Name.

You can manipulate the Bitting Array to hold constants as well as add or delete numbers.

Next click [Save & Go] and in less than 2 seconds the system will be created and loaded.

Notice the new "Client Menu" below, it's different from the Main Menu that we saw earlier.

This is the menu you see when you "Load Existing System" from the main menu.

We can Update Master Keys to select and assign which masters will be used for this client.

63 masters are listed starting with "Page" masters and higher but there are actually hundreds more.

The picture above is the Master Key List and the picture below is the Change Key List.

For small jobs, Vertical & Block Masters are shown. Special use Horizontal and Line Masters also listed for expert uses.

Most jobs will pin to a lower level like Page Master. Page Masters only require 3 master pins per lock.

Below you can pin many different levels including Line and Horizontal masters. Choose all keys or just Active (In-Use) keys.

In the Pinning Chart below we're pinning to the "Theoretical" so there are master pins in each chamber.

Notice that key# 230 is marked with an asterisk * indicating it as a declining step key which should be avoided.

In the last picture you can see the process for adding notes to any change key or master.
Notes can be as large as 375 characters.

Perfect Master 8 Pro is our most advanced Master Key System designed specifically for Windows.
