How to unlock the fitness bracelet Xiaomi Mi Band 5: 5 proven ways

The Xiaomi Mi Band 5 fitness bracelet has become one of the most popular wearables thanks to its combination of functionality and affordable price. However, even such simple gadgets sometimes throw up unpleasant surprises: the bracelet can suddenly lock after several failed attempts to enter a password, sync failure or update the firmware. If you see a lock icon or the words Lock on the screen, do not panic - in 90% of cases, the device can be unlocked without contacting the service center.

In this article, we will discuss all the current ways to unlock the Mi Band 5, including official methods from Xiaomi and little-known techniques that work even when software crashes. PIN-code, hardware failure or software glitch after the update, we will look at each scenario separately so you can choose the most suitable option.

1 Unlocking through the official Mi Fit/Zepp app

The easiest and safest way to do this is to use a Xiaomi app, which is suitable if the bracelet is locked because of multiple mistyping of the password or after reconnecting to a new smartphone. Importantly, for this method, you must have access to the Xiaomi account to which the bracelet is attached.

Step instructions:

• 📱 Open the Mi Fit app (or Zepp if you’ve switched to a new platform) on your smartphone.
• 🔗 Make sure the bracelet is connected to your phone via Bluetooth. If the connection is lost, reboot the Bluetooth module on your phone.
• 🔒 Go to the bracelet section (usually it is displayed on the home screen of the application).
• 🔑 Find Unlock Device or Unlock (depending on the application version). In some firmware, this item may be hidden in Settings. → Security.
• 📋 Follow the instructions on the screen. You may need to enter a password from your Xiaomi account or confirm the action through the SMS.

If the app doesn't have an explicit unlock button, try syncing the data with the bracelet - sometimes this automatically removes the lock.

1. Open the Profile tab in Mi Fit.
2. Select your Mi Band 5 from the list of devices.
3. Slip on the synchronization icon (circular arrow) in the upper right corner.

💡

If unlocking through Mi Fit didn’t work, try temporarily untie the bracelet from your account (select Delete Device in your device settings) and then re-attach it, which often helps with software failures.

2. reset to factory settings (Hard Reset)

If the bracelet is locked tightly and does not respond to commands from the application, hardware reset will help. This method erases all data from the device, including settings, statistics and associated accounts, but returns the bracelet to working condition. Use it only as a last resort!

How to make Hard Reset on Mi Band 5:

Disconnect the bracelet from the smartphone in Bluetooth settings|Make sure the battery is over 50%|Prepare. PIN-code from Xiaomi account for re-binding|Take screenshots of important statistics (if you need to save data)

-->

The discharge procedure itself:

1. Disconnect the bracelet capsule from the strap.
2. Find the reset button on the back of the capsule (a small hole next to the charging contacts).
3. Take a paper clip or toothpick, insert it into the hole and hold it for 10-15 seconds until the Mi logo appears on the screen.
4. Release the button. The bracelet will reset and return to factory settings.

After discharge:

• 🔄 Connect the bracelet to the smartphone again via Mi Fit/Zepp.
• 📲 Go through the initial setting (choice of language, account binding).
• ⚙️ Update the firmware to the latest version if the app offers to do so.

💡

Hard Reset removes all the data from the wristband, including activity history and alarm settings. If you want to keep statistics, try other unlocking methods first.

3 Unlocking through the hidden menu of engineering settings

Few people know, but there's a hidden engineering menu in the Mi Band 5 that allows you to bypass some locks, which works if the bracelet is locked because of a firmware failure or an application conflict. Importantly, not all firmware versions support this method.

How to open the engineering menu:

1. On the main screen of the bracelet, swipe your finger left-right-left-right-left (like the Contra code).
2. If the menu doesn’t open, try the up-down-up-down-up combination.
3. In the menu, find Unlock or Reset Lock (can be called differently depending on the firmware version).
4. Confirm the action by pressing the screen.

If the engineering menu does not open:

• 🔋 Check battery power – at levels below 20%, some features are turned off.
• 📱 Make sure the bracelet is disconnected from the phone (in some firmware, the menu is blocked when an active Bluetooth connection is in place).
• 🔄 Reboot the bracelet by holding the touch button for 10 seconds.

4 Unlocking through third-party utilities (for advanced users)

If standard methods don’t work, you can use third-party tools like Mi Band Tools or Notify & Fitness for Mi Band, which give you extended access to bracelet features, including unlocking. However, beware: informal utilities can disrupt the stability of the device.

Instructions for Mi Band Tools:

1. Download and install Mi Band Tools from Google Play.
2. Connect the bracelet to the application (you need to disconnect it from Mi Fit/Zepp).
3. Go to the Tools section → Unlock Device.
4. Follow the instructions on the screen, and you may need to confirm the action via root access (on some smartphones).

Warnings when using third-party utilities:

⚠️ Note: Apps like Mi Band Tools require advanced permissions and can conflict with official Xiaomi software. Once unlocked, it is recommended to return the bracelet to its original state through Hard Reset and re-attach it to Mi Fit.

Alternative utilities:

• 📱 Notify & Fitness for Mi Band – lets you manage notifications and some security settings.
• 🖥️ Gadgetbridge – open source software for working with wearable devices (requires technical knowledge).

5 Unlocking after firmware update

Sometimes Mi Band 5 is blocked after an automatic firmware update, which is due to a conflict between the new security settings and the old user data, in which case forced flashing through the official application will help.

How to reflash the bracelet:

1. Open Mi Fit or Zepp.
2. Go to the bracelet settings and find the Firmware Update item.
3. If a new version is available, start the upgrade process. If the bracelet is already on the latest version, try rolling back the firmware (see spoiler below).
4. After updating, the bracelet will automatically unlock and offer to undergo the initial setup.

If the bracelet is blocked during the update:

• 🔌 Connect the bracelet to charging and wait for full charging (at least 80%).
• 🔄 Reboot it by holding the touch button for 15 seconds.
• 📱 Re-run the update via Mi Fit.

Hardware malfunctions: when unlocking is not possible

If none of these methods worked, it may be a hardware failure, such as:

• 💧 Moisture in the body (even if the bracelet has protection 5) ATM, contact may oxidize).
• ⚡ Damage to the controller after a fall or impact.
• 🔋 Battery bloating that blocks sensor operation.

Signs of hardware malfunction:

⚠️ Warning: If the bracelet is physically damaged (cracks on the body, traces of oxidation on the contacts), do not try to unlock it software. This can lead to a complete failure.
