Xiaomi M365 Locker: A Complete Guide to Using a Scooter Lock

The Xiaomi M365 electric scooter has become one of the most popular vehicles in the city, but its compactness and high cost make it a tasty target for thieves. The original Xiaomi M365 Locker, a smart device that locks the rear wheel and integrates with the Mi Home ecosystem, helps solve the security problem.

In this article, we will discuss all the official and undocumented ways to work with the Xiaomi M365 Locker, including application binding, mechanical locking, resetting settings and solving typical errors. Particular attention will be paid to compatibility with different versions of scooters (M365, Pro, 1S, 3) and the nuances of use in 2026 – after firmware updates and changes in Xiaomi’s policy on working with accessories.

What is Xiaomi M365 Locker and how does it work?

The Xiaomi M365 Locker is a compact device weighing only 200 grams that attaches to the frame of the scooter and locks the rear wheel using a steel cable. Unlike traditional bicycle locks, it is equipped with:

  • πŸ”‹ Built-in battery (capacity 200 mAh, enough for 3-6 months with daily use).
  • πŸ“± Bluetooth module for communication with the Mi Home application (range up to 10 meters).
  • πŸ” Mechanical key in case of electronics discharge or failure.
  • 🚨 Vibration sensor that sends a notification to the phone when you try to hack.

When activated, the lock lock locks the cable in a closed position, locking the wheel. Unlocking occurs either through the application (by pressing the button in Mi Home), or by turning the mechanical key. Importantly, without binding to the Xiaomi account, the lock only works manually, without notifications and remote control.

If the lock does not respond to commands from the application, check the firmware version of the scooter. On the M365 1S and later, you need to upgrade to the minimum version 1.5.4 to work properly with the accessories.

Step-by-step: how to connect Xiaomi M365 Locker to the scooter

The process of linking the lock to the scooter and Xiaomi account consists of 4 steps. It is important to follow them strictly in order, otherwise the device may not be determined in the application.

  1. Install the mechanical part. Secure the base of the lock on the frame of the scooter with two screws (come with the kit). The optimal place is under the platform, closer to the rear wheel. Make sure that the cable passes freely through the spokes and does not interfere with the rotation of the wheel in the unlocked state.
  2. Charge the lock. Connect the lock to the network via Micro-USB (cable included) for 2-3 hours. The charging indicator should burn red, and after full charging - green. Do not use the lock with a discharged battery - this can cause a failure of the tether.
  3. Link to the Mi Home app. Open Mi Home, go to Profile β†’ Settings β†’ Add device. Select Transport category and find Xiaomi M365 Locker. Press Add and follow the instructions on the screen. The lock should flash blue light, which means it's ready to pair.
  4. Set up notifications. Once anchored, go to the lock settings in Mi Home and activate the options: πŸ””"Vibration notification” (sensitivity - average). πŸ”“"Auto-unlocking" (if the scooter supports). πŸ“"Location tracking" (requires switched on GPS phone-on).

If at the binding stage the application gives an error "Device failed to connect", try:

  • πŸ”„ Restart your phone and lock (hold the button for 10 seconds).
  • πŸ“± Update Mi Home to the latest version.
  • 🌍 Change region in Mi Home settings to China (sometimes helps with server problems).

How to use the lock: lock, unlock and emergency situations

After successful binding, the control of the lock is intuitive, but there are several nuances that are not written about in the official instructions.

Methods of blocking:

  • πŸ“± Through the app, open Mi Home, find the lock in the list of devices and click "Block." The lock will emit an audible signal and fix the cable.
  • πŸ”˜ Lock button: briefly press the physical button – the lock will be locked (if previously unlocked through the application).
  • βš™οΈ Automatically: on scooters with support for the function, activate in the "Blocking when off" settings - the lock will work when you press the power button on the scooter.

Methods of unlocking:

  • πŸ“± Mi Home: tap "Unlock" in the app, and the lock will emit a double signal.
  • πŸ”‘ Mechanical key: insert the key into the keyhole (under the lid) and turn counterclockwise.
  • πŸ”„ Emergency reset: if the lock is getting stuck, hold the button for 15 seconds until the beep is sounded – this will reset the lock (but will not untie the account).
What if the lock is locked with the key inside?
If the cable is locked when the key is inserted into the well, do not try to pull it out by force. Carefully turn the key 90Β° counterclockwise and pull on yourself - the mechanism will unlock. If this does not help, contact the Xiaomi service center with a passport for the lock (there is a warranty card in the kit).

If the lock is unlocked spontaneously (without a command from the app), it could mean:

⚠️ Firmware failure – update the lock via Mi Home (Service Update section) If no updates are available, reset to factory settings (hold the 20 seconds button).

⚠️ Low battery charge, recharge the lock, and if the charge level is below 10%, there may be false alarms of the vibration sensor.

Common mistakes and their solution

Even with the right installation, users face typical problems, and here are the most common ones and how to fix them:

Mistake.Possible causeDecision
The lock does not respond to the team from Mi HomeBluetooth connection failureRestart the phone and lock, check the distance (no more than 10 m).
The tether is not fixed.Mechanical wear and tear or pollutionClean the cable and grooves of the lock with alcohol, lubricate with silicone lubrication.
Permanent vibration notificationsHigh sensitivity of the sensorReduce sensitivity in the Mi Home settings or move the lock away from the engine.
The castle discharges in 1-2 weeksBattery malfunction or frequent useCheck the battery voltage (should be 3.7-4.2V). At low voltage, replace the battery.

If the lock displays a "Device offline" error in the Mi Home, but the indicator on it is lit green, try:

  1. Remove the device from the application and re-tether.
  2. Change the region in Mi Home to China (sometimes Xiaomi servers block the connection for other regions).
  3. Update the firmware of the scooter - on older versions, conflicts with accessories are possible.

πŸ’‘

If the lock is no longer defined in Mi Home after the app update, try to roll back to the previous APK version (e.g. 6.1.100).

Resetting settings and reassigning the lock to a new account

If you are selling a scooter or want to transfer the lock to another user, you need to perform a factory reset, which will delete all data about the previous owner and allow you to link the device to a new Mi Home account.

Resetting instructions:

  1. Make sure the lock is unlocked (use the key if necessary).
  2. Hold the button for 20 seconds until the indicator flashes red and blue alternately.
  3. Release the button - the lock will emit a long beep and return to the factory settings.
  4. Remove the device from Mi Home (if it is still displayed there).

Once the lock is reset, it'll be ready for a new tie.

  • πŸ“± Log in to Mi Home under a new account.
  • πŸ” Select "Add device" β†’"Transportation" β†’ Xiaomi M365 Locker.
  • πŸ”„ Follow the instructions on the screen (the lock should flash blue).

⚠️ Important: If the lock was tied to a Xiaomi account with two-factor authentication, you may need to enter a code from the two-factor authentication account to reset. SMS Or an email confirmation, without it, the device won't be able to get away from the old owner!

Alternative ways to use the lock

In addition to the basic wheel lock function, the Xiaomi M365 Locker can be used in a different way:

  • πŸ”— Like a bicycle alarm: if you don't have a scooter, you can lock it onto the frame of the bike and use a cable to lock the rear wheel. The vibration sensor will work, but location tracking may not be accurate.
  • πŸŽ’ To protect your backpack or bag, run the cable through the zipper of your backpack and lock the lock.
  • 🏠 Like a door opening sensor: lock the lock on the door of a cabinet or garage and adjust vibration notifications. Minus - no open / close sensor, only reaction to movement.

For non-standard use, consider:

  • The cable length is 80 cm, which is enough to lock a wheel or a small bag, but not for large objects.
  • The vibration sensor is triggered by any movement, so false notifications are possible in windy weather.
  • When fastening to non-metallic surfaces (plastic, wood), use additional screeds - screws from the kit may not hold the lock.

If you use a bicycle lock, turn off the Auto Unlock feature in Mi Home, otherwise the lock may accidentally unlock when driving on rough roads.
