- Unlock the workstation with a bracelet
- If a bracelet is out of Bluetooth range, Lock the workstation.
- Mi Band 2 - After updating the App "Xiaomi MI Unlock Tool" / "Mi Blaze Unlock" (小米智能解锁) Mi Band 2 bracelet is not supported. Maybe you can unlock it by editing the "MIBandUnlockApp.dll" file, by changing "Band3Name" and "firmware.LowerLimitVersionV3" to the requirements of Mi Band 2. Unfortunately I don't have Mi Band 2 to test it.

First thing first, you need to download "Xiaomi Mi Unlock Tool" / "Mi Blaze Unlock" (小米智能解锁) from the Windows Store. It’s free.
If for some reason you can’t access the app, you need to change your Region to China. To do so, go to Settings > Region& language and select China from the country list.
Restart the computer and now if you go back to Windows Store, you should be able to see the app now.
When your computer restarts, Go to Microsoft Store and search for "Xiaomi MI Unlock Tool" / "Mi Blaze Unlock" (小米智能解锁) in the search bar and install the app.
Launch the app and tap on the scan band tab. The app is simple and only has two tabs, one is for pairing and the other shows paired bands. This app can only pair one Mi Band.
Now your Mi Band should be powered ON and disconnected. You have to turn the smartphone’s Bluetooth OFF so that the Mi Band is free for pairing.
