Create and print master key systems in an instant with Master It!

Master It is perfect for small or on-the-fly systems. Create a master key matrix immediately with zero math and zero worries of cross-keying. Either enter in your own TMK or tap Randomize to create a completely master key system.

Master It is built to create a system immediately to print and keep in your records at your shop. Only one save slot is available to prevent multiple master key systems on your iPhone. The goal with Master It is to create and AirPrint a system in an instant. If on the road when printing isn't available, email and save features are secondary backups prior to printing. Email is also ideal when a printer is not AirPrint compatible.

Currently supports Yale .019", Weiser .018", Kwikset .023", Sargent .020", Schlage .015", and Arrow .014".

AirPrint, Email, or Save any system created.

Create 5 or 6 pin systems

When using Randomize, select the Shallow Depths option to limit the TMK to small bittings.

Tap anywhere on the matrix to select or deselect a bitting for the key chart.

All change keys can be personally labeled.

Up to 64 change keys and 1 sub master can be generated. After printing, it is possible to add to the matrix conventionally (pen on paper).

Use the Project Name and Keyway box for temporary saving information. The actual printout will allow you to write in the business name, personal name, address, keyway, and phone number conveniently (see the last screenshot).
