Features & Capabilities

FEATURED IN KEYNOTES MAGAZINE

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 complete master key system containing a single TMK, a single sub master, and up to 64 change keys. Each output delivers a fixed sub master and set of change keys.

Master It is built to create a system immediately to print and keep in your records at your shop. It is capable of saving and reloading one project at a time. 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:

Kwikset .023" Corbin Russwin .028" Weiser / Falcon .018" Ilco-Unican .018" Schlage .015" Arrow .014" Sargent .0125" & .020" Corbin .014"

Obeys MACS rules for each selected system.

AirPrint, Email, or Save any system created.

Create 5 or 6 pin systems.

Randomize feature to always generate a completely random TMK every time. Use the two filters to restrict the TMK to only shallow depths, or to always include the shallowest and deepest cuts.

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

Shake your iDevice to lock the primary functions on the main screen. This is to prevent unwanted changes (i.e. accidentally tapping Reset). To unlock, just shake again.

All change keys can be individually identified.

Use the Project Name / 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. After printing, the system can be continued manually on paper.

Additionally, you can tap on each change key to display the pinning.

Compatibility: All iPhone, iPad, iPod Touch types and generations with a minimum iOS version of 12.0

User Reviews

Overall, users find Master It to be a time-saving, easy-to-use tool for creating master key charts on the job. It shines for on-site use, quick chart generation, and straightforward output via save, email, or print. However, recurring drawbacks include a limited save/load workflow (only the last project loads), no ability to manually enter or customize existing key cuts, and functionality gaps for full master-to-pin calculations or higher-level stages. A lack of documentation is also noted, with requests for tutorials.

Pros

Saves time by quickly generating master key charts
Easy to use and well organized
Output options to save, email, and print results
Flexible with many key systems and pin configurations
Handy for on-site work (works well on the road)

Cons

Save/Load feature only loads the last project; difficult to manage multiple saved jobs
Cannot manually enter existing key cuts or customize specific numbers
Does not calculate master-to-individual pin sets or higher-level master schemes (stages 3/4)
Limited documentation or tutorials to explain usage and features

So far this app seems like a good app. As far as starting a master system from scratch, very helpful. But, my only complaint is that I wish it allowed you to manually enter key cuts for already exsisting keys. For example: a locksmith is called out to a newly constructed apartment building. The contractors have already installed all the door locks (each having its own key). The manager wants the locksmith to make a master key to all of the already installed locks. Yes it still would require the locksmith to add the master pins to each lock, but the locks already have their own cut keys. Point I’m getting at is, the app right now will not allow you to go in and manually enter each existing key cuts and then be able to give you a quick reference on master pins that need added to each lock. The app only generates key cuts to be made on each new key as well as what master pins to put in. It would be nice if this was updated.

I found this app to be great for small and quick jobs but I’m not sure what the point of the Save/Load feature is. I can’t seem to find anyway to load previous projects. It only seems to load the last one worked on. It would be perfect if I could save and re-load multiple jobs.
