Features & Capabilities

A2 Small Format Interchangeable Core Calculator

---Programmed by a Locksmith, for Locksmiths---

Automatically calculates the pinning chart for A2 SFIC. Built for 6 or 7 pin systems, however, less can be achieved by using a decimal to erase a chamber.

Minimum of a control and master key are required to make a chart. Additional change key available for all devices; 2 change keys available for 4" (and above) screen devices.

Randomize function will generate completely random charts each time it is triggered.

"Lock/Unlock" toggle disables/enables all inputs and functions to prevent unwanted/lost changes.

Control Finder is an added bonus by reverse engineering a core to determine the control key's bitting. This is perfect when needing to remove multiple cores in a building when the control key has been lost. There are two methods for achieving the control key: 1. using the master, control, and bottom pins, or 2. using only the top/driver pins.

Up to 16 different projects can be saved at any one given time.

All projects are encrypted and protected with a passcode.

AirPrint or Email projects with a single tap.

Compatibility: iPhone / iPod touch on iOS 8.0 or later and iPad on iOS 12.0 or later.

Nice app except for saving pin settings. When it ask to change password app closes and does not save new password. App also closes when trying to input the default password.

Who does math by hand anymore? This app saves you from having to ever fill out a bitting chart again. Quick and easy!

This app pays for itself over and over and over. I’ve rekeyed 4 casinos and a airport using this handy app cuts my bitting generation times in half. The control finder is an added bonus in tight situations as well. Thanks Phil!
