Description
Precision Locksmithing, Simplified.
Stop doing math at the bench and putting down your tools to check paper charts. Locksmith Calculator is the ultimate companion for professional locksmiths, helping you convert measurements into accurate key codes and calculate complex pin stacks instantly.
Whether you are decoding a customer's key or re-pinning a cylinder from scratch, this app does the heavy lifting for you.
KEY FEATURES:
1. Key Calculator (Decoding)
From Cut to Code: Measure key cuts using your calipers, and the app instantly returns the correct cut depth (e.g., measuring 6.60mm returns a #2 cut).
Pin Buildup: Automatically calculates the bottom and master pins required for the decoded key.
Visual Feedback: Dynamic display builds the key as you enter data.
Bluetooth Ready: Connect your Bluetooth Digital Calipers (in Keyboard mode) to input measurements directly without typing!
Direct Entry: Already know the cuts? Use the checkbox to manually type the key code (e.g., "23143") for an instant pin chart.
2. Pin Calculator (Gauging)
From Pin to Bitting: Measure loose pins taken out of a lock to reverse-engineer the key bitting.
Multi-Chamber Workflow: Navigate through chambers 1–6. The app intelligently assumes the first pin is the Bottom Pin and subsequent pins are Master Pins.
Permutation Generator: Once measured, the app calculates all possible valid keys that will operate that specific pin stack (e.g., generating both User and Master keys).
Undo Function: Made a mistake? Easily remove the last pin measured without restarting.
3. Key Gauge
Quickly verify measurements against standard manufacturer specifications.
PROFESSIONAL TOOLS:
Metric & Imperial: Toggle between MM and Inch globally with a single tap. Perfect for users worldwide.
Database Updates: Checks online for the latest key blank and depth data, so you are always up to date without needing to update the whole app.
Share & Export: Copy your decoded key codes and pin charts to the clipboard or share them via email/messenger directly to your office or customer.
Manufacturer Support: Includes data for a wide range of manufacturers and keyways (e.g., Lockwood, Silca, etc.).
Designed by a Locksmith, for Locksmiths. Stop guessing and start originating with precision.
(Note: This app requires a subscription for full access to all calculation tools).
Recent changes: Added ability to create your own custom profiles for decoding keys.

Aside from changing measurements from MM to Inches, there is literally nothing you can do in this app, until you "subscribe". I'm very disappointed as I only wanted to try it out to see if it might be worth the subscription. Is this a way to boost install numbers? 😞 Edit: It says "(Note: This app requires a subscription for full access to all calculation tools).", which insinuates that some tools are available without subscription. Perhaps a change of wording would be in order?
