What is Milwaukee ONE-KEY™?

Milwaukee’s ONE-KEY™ system has brought game-changing innovation to the power tool industry, making it a key feature in many of their top cordless models. Using Bluetooth, ONE-KEY™ lets you connect your smartphone to your Milwaukee tools, enabling remote management, tracking, and customisation. This comprehensive system offers a range of powerful features designed to boost efficiency, improve tool security, and enhance overall job site control. This blog post dives into what ONE-KEY™ is, highlights its best features, and showcases some of our favourite ONE-KEY™ compatible tools.
What is Milwaukee ONE-KEY™?
Milwaukee ONE-KEY™ is a digital platform integrated into many of Milwaukee’s cordless power tools. It offers simplified and efficient tool customization, tracking, and management on the job site. Using Bluetooth connectivity between your power tool and the smartphone app allows you to build digital inventories, share information in real-time with team members, and easily oversee tool locations and other services.
These features not only allow you to keep your tools more secure and available but also allow you to work more efficiently by tracking every aspect of them. You can even manage your team members and automatically report on your tool’s performance data to ensure it’s always working at full capacity.
Milwaukee ONE-KEY™ Features
ONE-KEY™ brings with it several unique key features which set it apart from the rest:
- Tool customisation
- Tool security & tracking
- Inventory management
- Tool reporting
Let’s dig a bit deeper into each of these below.
Tool Customisation
With the ONE-KEY™ system, you can wirelessly configure your tools to better suit the jobs you do most frequently. For example, you can adjust the speed and torque settings in an impact wrench or combi drill for use with a specific material or task.
Using the app on your smartphone, you can set up customisable profiles containing these custom settings for your tool. These are then stored in the tool meaning that they can be easily saved or loaded, and that your smartphone doesn’t need to stay connected.
In addition, ONE-KEY™ uses advanced electronic sensors to monitor the tool’s output and performance, ensuring a consistent and controlled power delivery with each trigger pull.
These features not only allow you to get in and out of jobs quicker but also maximize tool performance and accessory life, allowing you to get the most out of your tools.
Tool Security & Tracking
Locating your tools has never been easier with the ONE-KEY™ app. Using the Bluetooth connection, you can precisely pinpoint the location of your power tool and see its location on an area map. This helps save you time and effort, as you don’t need to constantly keep an eye on all of your tools; instead, you’ll be able to see exactly where they are at a glance.
The handy Geo-Fencing feature allows you to set up an invisible perimeter around a job site, and if a tool assigned to that area is seen outside of it, you’ll receive an alert on your smartphone. You will no longer need to worry about equipment missing from job sites!
However, if your tool goes missing, the ONE-KEY™ app will alert you if this tool comes within 30 feet of anyone else with the app installed. You can then lock down the tool, preventing anyone from using it unless you reset it yourself.
Inventory Management

Milwaukee ONE-KEY™ features a centralized inventory management system that allows you to track all tools and equipment across your users and networks, regardless of location.
The smartphone application shows you a digital catalogue containing every compatible tool and barcoded item in your inventory so you can easily verify what you have on hand. At a glance, you’ll be able to see details such as tool location, job history, where it is assigned, and who it is assigned to
Another handy inventory management feature of ONE-KEY™ is its ability to send automated service reminders for your tools. You’ll be alerted when your attention is needed so that you can ensure your tools are working at full performance and maintaining their long-term durability.
Tool Reporting

Thanks to Milwaukee’s advanced electronics monitoring, job site managers can wirelessly synchronize their tools to the web-based app and automatically upload tool data and history. This comprehensive reporting system allows you to drill into every detail of your tool’s performance and efficiency.
The software will track performance and information like timings, torque, electrical terminations, or crimp actions. With this information, you can schedule regular reports or create custom reports to help spot potential problems or issues before you finish the job.
