Free Master Keying Tools

Generate master key systems, build pinstacks, and keep running pinout sheets in one browser-based workflow. Project Atlas is built for locksmiths, security teams, facility staff who need usable tools on desktop or mobile interchangeably without the risk of handing system data to some other company's server. It provides SSL encrypted sessions to build and manage systems on the user's end, virtually anywhere. Your system files are only saved locally, and you get the flexibility to use pretty much any device with a browser.

Generator + Calculator Create systems, review the tree, color-code key availability, and build cylinder pinning from generated systems or manual key entry.
Running Pinout Sheets Save clipboard entries with cylinder quantities and running pin count totals for live bench or field work.
Reloadable Projects JSON files restore system inputs, key status decisions, and saved clipboard work so active jobs can be reopened quickly.
Installable + Offline Ready Install Project Atlas as a web app and keep working from the counter, truck, bench, job site, or a dead zone once the app is cached.

Cached For Offline Use

Once Project Atlas has been loaded on a device and it automatically loads the last cached app version from the last connected instance, users can still operate the app, review systems, and update project files even in a dead zone because system data is only stored locally on your device, never on this server. Once viewed online it should load without internet and function normally.

System Generation

  • Generate full systems with progression rules and MACS-aware filtering.
  • Supports common 4-7 cut manufacturers, including SFIC and LFIC DSD profiles.
  • System JSON files reopen live Atlas projects without rebuilding from scratch.

Locksmith Focused

  • Built around real system design, cylinder pinning, and update-heavy locksmith work.
  • Review generated systems in browser, color-code available, activated, and deactivated keys, and build pinstacks directly from the system tree.
  • Track cylinder quantities and cumulative pin totals as clipboard entries grow.
  • Useful for apprentices and technicians learning progression, hierarchy, and pinning logic in a free and forgiving software setting.

Export Ready

  • Export the full project zip as your primary save method so the JSON, workbook, and pinning sheets stay synchronized with ongoing edits and key status decisions.
  • Copy or download clipboard batches for bench notes, field work, or documentation.
  • Project data stays with the user, not on a hosted system database.

Practical Mobile Ready Locksmith Software For Master Key Planning And Fast Cylinder Pinning

Project Atlas keeps master key planning, cylinder pinning, running pinout sheets, and reloadable browser workflow in one place for locksmiths, facility teams, and property managers. Build or manage any time, anywhere, on any device with a browser. Once you login and load the app, the cached version of Project Atlas can continue to be used while offline until you sign out.

Built For Search. Built For Work.

Master key software, pinstack calculator, and browser-based project recall in one place.

Launch Generator
Mobile Workflow That Still Shows Real Detail
  • Search the hierarchy, inspect pinstack output, and manage pinout sheets from a phone or tablet.
  • Use the same browser workflow at the counter, in your van, at the bench, or on site.
  • JSON reload support preserves project state, running pinout sheets, quantities, and pin totals.
  • When installed or cached ahead of time, Project Atlas can still open and run offline using the last cached app files.
For Locksmiths
Build systems, check pinstacks, and move multiple cylinder pinouts into one copy-ready list for field or shop use while tracking cylinder/core quantities and cumulative pin counts.
For Property Managers
Plan clean master key structures, document system changes, and keep project information organized for maintenance and turnover work. Easily share systems with your locksmith of choice to implement them for you, while maintaining your own records.
Great For Training And Apprentices
Use the generator and pinstack tools as a hands-on reference for learning progression, hierarchy layout, and real-world cylinder pinning workflow. This app presents a free and forgiving software environment you can provide seperately from your shop's usual system generator, providing apprentices a safe place to build, learn, and experiment without the risk of giving them unsupervised access to your system data.

Need Cylinder Pinning Without Building A Full System?

Use the standalone pinstack calculator for manual key entry, quick field reference, or systems created in AND outside of Project Atlas.

  • Manual key labels and bittings for outside systems or bench work.
  • Generator-style pinning rules for standard cores, or small and large format IC workflows.
  • Running clipboard entries with quantities, copy or download output, and cumulative pin totals.

Fast. Direct. Built For Real Work.
Manual Key Entry
Add your own key labels and bittings to work with outside systems or for quick bench work.
IC-Aware Output
Automatically handles control-key driven buildup and top-pin output where required. Control can be toggled on/off for systems using mix of IC and conventional cores on same keyway.
Clipboard Ready
Build a running clipboard list of multiple cylinder pinouts, then copy the whole set out in one clean output for the bench or the field, complete with cylinder quantities and running pin totals. Save a JSON file to reload and continue editing later.

New: Progress Replacement Keys With Partial Reads
The Universal Progression Chart tool is designed to help locksmiths and technicians generate possible key bitting progressions when working with automotive keys or any keyway where only some cuts are known.

Enter known cuts, set MACS and cut range, and get a visual chart of all possible bitting progressions. Mark off eliminated bittings as you go, and save or reload your work as a JSON file.

  • Visual progression chart for missing cuts
  • MACS and cut depth range support
  • Known cuts input and auto-advance
  • Mark eliminated bittings for quick reference
