The long-awaited Xiaomi Mi Band 4 / Mi Band 4 NFC version sensor key function has finally available. After turning on the Mi Band 4 sensor key function, you can unlock the Xiaomi notebook or RedmiBook. In this post, let's teach you how to achieve this function in detail.

How to Unlock Your Windows Laptop with Mi Band 4?

Step 1: Update your Mi Fit APP to the latest 4.0.15 version.

Step 2: Go to the Mi Fit APP and tap the “Profile-My Devices-Mi Band 4-Lab.” And then, switch on the “Unlock MiBook”.


Step 3: Download Mi Unlock Tool from the Windows Store.


Step 4: Launch the Mi Unlock Tool 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.


Step 5: Pairing your Mi Band 4 with your MiBook or RedmiBook.

On your Windows computer and in the Mi unlock tool, scan for the Mi Band 4, it might take a minute or two but it would discover and prompt you to bind the band with the app.

Press the button on the Mi band 4 to do that. After it is successfully paired it would then ask your windows credentials for authentication. Enter the details and press OK.
