How to install the code on the suitcase Xiaomi: full instructions with photos and tips

Xiaomi’s smart suitcases are not just a stylish travel accessory, but also a high-tech, digitally protected device. The ability to set a personal code on a suitcase lock protects your belongings from unauthorized access, and built-in features like location tracking or weighing make travel more comfortable. However, many users have difficulty setting the code first: they can’t activate the lock, forget the combination, or don’t understand how to reset.

In this article, we will discuss how to properly install the code on the Xiaomi suitcase (including Mi Travel models, 90Fun Smart Suitcase and others), what to do if the lock does not respond, and how to avoid typical errors.

Which Xiaomi suitcases support digital code?

Not all Xiaomi suitcases are equipped with electronic locks, the code installation function is only available in smart models with Bluetooth and mobile app support.

• 🔒 Xiaomi Mi Travel Smart Suitcase – flagship line with the TSA-lock, digital panel and control through the Mi Home app.
• 📱 90Fun Smart Luggage – budget option with an electronic lock, but without GPS-tracking.
• 🔄 Xiaomi Youpin Smart Suitcase – models with automatic weighing and fingerprint unlocking (in some versions).

To check if your suitcase supports code installation, note that:

• 🔢 Digital panel with buttons (usually located next to the handle).
• 📲 Mi Home or Bluetooth logo on the body.
• 🔋 Charging indicator (if the lock is powered by a battery).

⚠️ Xiaomi suitcases without a digital panel (such as classic Mi Business Suitcase models) do not support code installation.

Before you start setting up, make sure that:

All factory stickers removed from the lock|The charge of the lock battery is not less than 30% (if there is an indicator)|The official instructions are on hand (usually in the pocket of the suitcase)|Mi Home app installed (for Bluetooth models)-->

If your suitcase has been in use, it may have an old code on it, which would require a factory reset, and we'll explain how to do that in one of the following sections.

Step-by-step: how to install the code on the suitcase Xiaomi

The process of installing the code varies depending on the model, and below is a universal instruction that is suitable for most of the brand’s smart suitcases.

Method 1: Install code through a physical panel (for models without Bluetooth)

This method is suitable for 90Fun Smart Luggage suitcases and some versions of Mi Travel.

1. Make sure the suitcase is unlocked (the factory code is either 000 or 0000).
2. Find the SET button on the digital bar (usually located on the side or under the cover).
3. Press and hold the SET for 3-5 seconds until you hear an audible signal (or an indicator lights up).
4. Enter a new 3- or 4-digit code (e.g., 1234).
5. Confirm the input by re-pressing SET.
6. Check the operation of the lock: close it and try to open it with the entered code.

If the lock does not respond to input after installing the code, try restarting it: remove the battery (if it is removable) for 10 seconds and insert it back.

Method 2: Install code through the Mi Home app (for Bluetooth models)

For Mi Travel Smart Suitcases with Mi Home support, the setup process is simpler:

1. Open the Mi Home app and add a new device (+ → Suitcase).
2. Choose your model from the list (e.g. Mi Travel Smart Suitcase).
3. Follow the instructions on the screen: turn on Bluetooth, hold the phone to the suitcase.
4. After connecting, go to the Settings of the lock → Set the code.
5. Create and enter a new code (from 4 to 6 digits).
6. Save the changes and check the lock.

Additional functions are also available in the app:

• 🔓 Opening by approximation (suitcase opens automatically when the phone is nearby).
• 📍 Location tracking (if built into the suitcase) GPS-module).
• 🔋 Notifications about low battery charge of the lock.

💡

If the Mi Home app doesn’t find a suitcase, try restarting Bluetooth on your phone or updating the device’s firmware through the app’s settings.

What to do if you forget the code from the suitcase Xiaomi?

Forgetting the code from the lock is a common problem, especially if you rarely use a suitcase, and the way you restore access depends on the model:

If none of these methods worked, contact Xiaomi’s service center with proof of purchase.In some cases, you will need to physically break the lock, which may void the warranty.

⚠️ Attention! Don't try to disassemble the electronic lock yourself, it can damage the mechanism. In models with lithium batteries, an improper reset can lead to a short circuit.

Hidden features of Xiaomi smart suitcases you didn’t know about

In addition to basic code protection, Xiaomi’s smart suitcases have a number of useful but little-known features:

• 🔋 Automatic lock shutdown at low charge – if the battery is discharged, the suitcase is unlocked to prevent loss of access.
• 📲 Remote unlock – In some models, you can open the lock through Mi Home, even if you forget the code.
• 🔊 Sound signal when shaking - helps to find the suitcase on the luggage belt.
• 📊 Travel statistics - the application keeps track of the number of flights and wheel mileage.

To activate these functions:

1. Open your Mi Home and select your suitcase.
2. Go to the Additional Settings.
3. Enable the necessary options (for example, Sound signal or Remote unlock).

Common Errors When Installing Code and How to Avoid Them

Many users have problems configuring the lock, and here are the most common errors and solutions:

• ❌ No code is saved, check if the lock's battery is discharged. USB-port (if any).
• ❌ The lock doesn't respond to the buttons -- it may have jammed the mechanism.
• ❌ App doesn’t see suitcase – upgrade Mi Home to latest version or reinstall it.
• ❌ The code is reset after the flight, and some airports use equipment that can knock down the settings of electronic locks.

If the suitcase stopped responding to the code after falling, the sensor or control board may have been damaged, and only repairs at the service center will help.

💡

Always test the lock before you travel – enter the code 2-3 times to ensure that you are running smoothly.

How to care for the electronic lock of a suitcase?

To keep the castle lasting, follow the simple rules:

• 🚿 Avoid moisture – despite the declared moisture protection, electronic components can fail when wet.
• 🔋 Check your battery power regularly – a discharged battery can block access to things at the most inopportune moment.
• 🧴 Clean the lock buttons - dust and dirt can cause jamming. Use dry soft cloth.
• ✈️ Do not hand over the suitcase with the Antivor mode on - this can cause false positives in the luggage compartment.

If you are keeping your suitcase in storage for a long time, remove the battery (if possible) or at least once every 2-3 months, turn on the lock to prevent discharge.
