Project Atlas is now WLS Locksmith Tools!

Free Locksmith & Security Pro Software Suite

Generate master key systems, build pinstacks, keep running pinout sheets, and create progression charts, all in one browser-based workflow. WLS Locksmith Tools are 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 WLS Locksmith Tools as a web app and keep working from the counter, van, bench, job site, or a dead zone once the app is cached.

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

WLS Locksmith Tools keep 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.

Cached For Offline Use

Once WLS Locksmith Tools have 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.

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, WLS Locksmith Tools 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.

Standalone Pinstack Calculator

Use the standalone pinstack calculator for manual key entry, quick field reference, or systems created in AND outside of WLS Locksmith Tools software.

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.

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.

WLS Locksmith Tools stay free in beta, runs on desktop and mobile, can be installed as a web app for offline field access after caching, let's you save and manage system data, export spreadsheet, and save, copy, or download and print pinout sheets, practical for live updates instead of one-time generation.

Universal Progression Chart

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 the cuts you can read, and the tool will chart all valid possibilities for the missing positions—making it ideal for progressing replacement keys when you have a partial read for a key bitting.

Generate universal key progression charts with MACS and cut depth support.
This tool helps locksmiths and professionals quickly generate, save, and reload progression charts for automotive and other keys. 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.

Welcome to WLS Locksmith Tools, a master key system generation tool provided by Williams Lock Service. By accessing or using this application, you agree to the following terms and conditions.

1. Acceptance of Terms

By selecting "Accept" below, you acknowledge that you have read, understood, and agree to be bound by this User Agreement. If you do not agree, you must select "Decline" and discontinue use of the application.

2. Intended Use

WLS Locksmith Tools are designed to assist locksmiths and security professionals in generating master key systems for planning and reference purposes.

Use only for lawful purposes
Only for systems you are authorized to design or service
Must comply with applicable laws and standards

3. No Guarantee of Accuracy (IMPORTANT)

This tool is provided as a reference aid, not a substitute for professional judgment.

All generated systems and bittings must be independently reviewed
You are solely responsible for system functionality and security
Unexpected or invalid results may occur, especially with edge-case parameters

4. Beta Software Disclaimer & Data Responsibility

WLS Locksmith Tools are currently in a beta stage.

Features may change or break without notice
Bugs or calculation errors may occur
Not all configurations are fully tested

Additionally:

Users are strongly encouraged to download and retain copies of all generated systems
System viewer conflicts or display issues may occur
Never rely solely on a system token to retrieve system data

5. Data Storage & Privacy Model (IMPORTANT)

This application is designed to minimize data retention.

Generated systems and exported project content are NOT stored on WLS Locksmith Tools servers or in the WLS Locksmith Tools authentication database
Systems are recalled using system tokens and user parameters or locally saved json files
Account sign-in and sign-up are processed through Supabase authentication services used by WLS Locksmith Tools
When you create an account, WLS Locksmith Tools send your email address, password, optional organization name, and related account metadata such as beta-access and professional-use flags to that authentication service
Account and authentication records may remain with that authentication provider until deleted or otherwise removed from the account system
WLS Locksmith Tools may store application files and related resources in your browser cache, service worker storage, and local browser storage to support offline use, app installation, performance, and session persistence
WLS Locksmith Tools may also store authentication tokens, session timing data, offline authorization state, and basic signed-in UI state in local browser storage or session storage on your device
This local browser storage occurs on your device, not on Williams Lock Service servers
Exported json files, spreadsheets, and pinning sheets saved by the user remain local files on that device unless the user moves or shares them elsewhere
Acceptance of this agreement is stored locally in your browser so the application can remember that choice on later visits
If email confirmation is required, authentication callback parameters may briefly appear in the browser address bar until the app clears them after processing
Clearing browser data, site data, or installed app data may remove cached files, offline functionality, saved local preferences, and agreement state
Requests to correct or delete account information must be directed to Williams Lock Service using the contact information below and may depend on capabilities available in the authentication provider
Loss of system token and/or downloaded files can result in permanent data loss for pinout sheets. The safest practice is to export the full project zip whenever you finish editing and replace your locally stored project folder with the updated extracted folder. In the event of file loss, json files can be recovered in the generator by loading the system token on your spreadsheet at the bottom of the generator page.

Security Best Practices:

Use blind codes or internal client numbers instead of real names
Maintain your own secure mapping of those codes
This prevents system data from being tied to real clients
Only enter organization information you are comfortable associating with your WLS Locksmith Tools account
Sign out of the app on shared devices when finished, but remember that sign-out does not protect files already saved locally on the operating system
Protect exported project folders the same way you would protect any other sensitive files stored on the device

6. Limitation of Liability

Williams Lock Service shall not be held liable for:

Errors in generated key systems
System failures or key conflicts
Security vulnerabilities
Loss of access due to missing system tokens or files
Any damages resulting from use of this tool

7. User Responsibility

Verify all outputs before use
Ensure compatibility with hardware and keyways
Maintain proper security practices
Safeguard system tokens and downloaded data

8. Modifications to Agreement

This agreement may be updated at any time. Continued use constitutes acceptance of changes.

Your use of WLS Locksmith Tools authentication features is also subject to the availability and processing practices of the third-party authentication provider used by the service.
