Frequently Asked Questions

Why won't my Milwaukee tool connect to the ONE-KEY app?
The most common causes are insufficient Bluetooth range (stay within 6 feet), missing app permissions for Bluetooth and location services, or interference from other wireless devices. Follow the systematic troubleshooting steps to resolve connectivity issues.
Do I need location services enabled for ONE-KEY to work?
Yes, location services must be enabled for the ONE-KEY app to function properly. This is required for Bluetooth Low Energy (BLE) device discovery and tool tracking features, even when not using GPS-based location tracking.
How close does my phone need to be to pair with Milwaukee tools?
Your smartphone should be within 3-6 feet of the Milwaukee tool during pairing. The Bluetooth connection range may be reduced by metal objects, concrete walls, and interference from other wireless devices in the area.
Can I pair multiple Milwaukee tools to one phone?
Yes, the ONE-KEY app supports pairing multiple compatible Milwaukee tools to a single smartphone. Each tool will appear separately in your tool inventory with individual settings and tracking capabilities.
What should I do if my Milwaukee tool pairs but keeps disconnecting?
Frequent disconnections usually indicate weak battery levels in either the tool or your phone, Bluetooth interference, or being at the edge of the connection range. Ensure both devices are fully charged and stay within close proximity during use.
