Itโ€™s important to understand that Xiaomi has integrated Smart Lock on several levels: itโ€™s a system feature MIUI, and an option in the Mi Home ecosystem for smart devices, and individual settings in applications like Google Smart Lock. Weโ€™ll look at each case with the latest updates in 2026, when the logic of the function has changed. If youโ€™re looking for a way to work specifically for your model, check the version of MIUI in the settings (Settings โ†’ Phone โ†’ MIUI version), as the location of menu items may differ.

4. Reset Smart Lock settings via ADB (for power users)

If the Smart Lock does not turn off via the interface (for example, due to a system failure or custom firmware), you can use the ADB command. This method requires connecting the phone to the computer and enabling the developer mode.

What if the ADB does not recognize the device?
If the adb device command doesn't show your phone: 1. Install the latest Xiaomi drivers USB Drivers from the official website. 2. Check if debugging is enabled by USB (Sometimes you need confirmation on your phone when you connect. 3. Try another one. USB-cable (preferably original). 4. Reinstall Android SDK Platform-Tools on PC.
