SFIC Pinning Calculator Tool Launched


We have launched the Pinning Calculators page in the Tools Section with our first downloadable pinning calculator. This pinning calculator covers all three pinning systems used in standard Small Format Interchangeable Core products from almost every manufacturer. This tool will allow locksmiths to quickly and easily calculate the pin combinations needed for 2-Level master keyed and non-mastered SFIC systems.


This tool is optimized for desktop use and requires Microsoft Excel, LibreOffice Calc, or any similar program capable of working with .xlsx files. Simply download the file and open it in your spreadsheet application of choice. Instructions are included on each page and the pinning array will automatically adjust as you enter your key bittings, including shading pins to alert you to invalid pin combinations.

Future Updates

In the near future we plan to introduce additional calculators supporting more brands and pinning systems as well as calculators capable of dealing with more complex master keyed systems.

Door Closer Footprint Comparison Version 3.0 Released

We have updated the Door Closer Footprint Comparison Chart in the Tools Section. We’re now at version 3.0 with 40 manufacturers/brands, 34 unique footprints, 289 unique models represented in the chart. We have added an additional manufacturer and removed from hyperlinks from hyperlinks from unique models (there were too many issues with encoding). Instead, the locksmith is instructed to consult our Parallel, Regular, and Top-Jamb page in the Library to locate installation manuals, spec sheets, and related manufacturer literature.
As always, footprints are organized by horizontal center-to-center measurements, smallest to largest. If multiple footprints exist with the same horizontal center-to-center measurements, they are further organized by vertical center-to-center measurements, smallest to largest. Manufacturers/brands are organized alphabetically. Column A is freeze paned for the included footprints. Row 1 is freeze paned for the included manufacturer/brands. This means that as you narrow down a specific model/models or manufacturer/brands, this information stays locked in your screen. This allows you to quickly find information.

One Page SFIC Pinning Chart

We’ve recently added a new pinning worksheet to the Pinning and Decoding Worksheets page in the Tools section. Under the SFIC tab, you will find two files named “One Page SFIC Pinning Chart”. This chart allows you to put together the entire pinning chart for a 7 pin SFIC master key system on a single page. Sounds too good to be true? It isn’t.

How it Works

This sort of pinning chart has been around for many decades but I’ve never seen it in a digital format. We sought to change that by making available in PDF and Excel formats.
To generate this pinning chart, you simply have to input your TMK and Control key bitting information. From there, you list your 4 progressives for each chamber and then use accepted SFIC formulas to determine your pin segments. Once fully generated, you move from box to box, matching the change key bittings, to successfully pin a core.
Let’s do a walk through to illustrate how it’s done. Here is a simple system I have put together:

As you can see, I have listed all possible progressives (green) for the TMK bitting (blue). Each box for each progressive contains the bottom, master, and build-up pins. Since all possible progressives will share the same top pin, the appropriate top pin is listed above each chamber’s column. With this chart completed, I just have to find the appropriate bitting for the appropriate chamber to determine my appropriate pinning. For example, if I need to pin a core to a change key bitting 1-4-7-7-5-8-1, I simply have to navigate as follows:
In the first chamber, I find the box for the 1 bitting and pin according to it. For the second chamber, I find the box for the 4 bitting and pin according to it. This goes on until I have pinned all 7 chambers. It’s that simple.
We have color coordinated specific areas of the Excel file to make it easier to navigated. Control key bittings are displayed in red, TMK bittings in blue, and progressive bittings as green. Additionally, we have included an area at the bottom of the page to keep constant pin stacks separate from progressed pin stacks to avoid any confusion.


There are few, powerful benefits. As stated earlier, you can generate an entire pinning chart for an entire system, save for special circumstances, on a single page. This allows you to save tremendous space in your truck and/or master key file(s). Second, it saves on time. If you generate this entire pinning chart immediately after creating the master key system, it’ll be the only time you’ll ever need to create a pinning chart for that system, again, save for special circumstances.
