The keyboard on Xiaomi smartphones is not only a virtual layout on the screen, but also physical buttons (for example, on devices with a retractable mechanism like the Mi Mix 3 or Black Shark), as well as touch zones under the display. If the keys stop responding, stick or fall off, their replacement becomes necessary. But where is it better to do this – in an official service, a third-party workshop or with your own hands?
In this article, we will look at all the options, from the addresses of authorized service centers Xiaomi in Russia and the CIS to step-by-step instructions for self-replacement. You will learn how much it costs to repair, what tools you will need, and how to avoid typical mistakes when disassembling a smartphone.
Xiaomi official service centers: addresses, prices and terms
If your Xiaomi is still under warranty, you should contact an authorized service center (ASC) that guarantees original parts, warranty obligations and professional repair. However, not all models are officially supported - for example, for POCO or Redmi Note older than 2 years, parts may be missing.
A list of official Xiaomi SCs in Russia and CIS countries can be found on the website mi.com/service. Enter your city or region, and the system will show the nearest points. Please note: some centers work only with warranty devices, and for post-warranty repairs can be redirected to partner workshops.
- 📍 Moscow: Letnikovsky str., 10 (SC "Mi Electronics"), Tverskaya str., 20 (SC "Xiaomi Russia")
- 📍 St. Petersburg: Marshal Govorov Street, 35, TRK "Gulliver"
- 📍 Kiev: Vladimirskaya St., 49a (SC "Mi Ukraine")
- 📍 Minsk: Independence Avenue, 163, Crown shopping center"
The cost of replacing the keyboard (or buttons) in the official service depends on the model. For example, for Xiaomi Mi 11 Ultra repairs will cost 3,500-5000 ₽, a for Redmi Note 10 Pro - at 1,800-2,500 ₽. The deadlines are usually 3-7 working days, but during peak periods (before the holidays) can be delayed up to 2 weeks.
⚠️ Note: If the smartphone was purchased in Europe or China, the official service in Russia may refuse repairs due to differences in firmware and configuration.
Third-party workshops: how to choose a reliable master
Informal service centers often offer lower prices and quicker deadlines, but there are risks: unoriginal parts, poor-quality soldering or damage to other components. To avoid problems, check the workshop by the following criteria:
- 🔧 Reviews: Look for a workshop on Yandex.Maps, 2GIS or Google Maps with a rating of at least 4.5. Pay attention to the latest reviews (over the past 3 months).
- 🛠️ Warranty: Reliable workshops give a 3-month warranty for repairs.
- 📱 Specialization: Find out if they work specifically with Xiaomi.Some workshops specialize only in iPhone or Samsung.
- 💰 Price transparency: A true professional will give you an estimate before a diagnosis. If a master refuses to give you a price, that's a bad sign.
Average prices in third-party workshops for replacement of keyboard (buttons, touch areas):
| Smartphone model | Cost of repair (₽) | Date(s) |
|---|---|---|
| Xiaomi Mi Mix 3 (retractable keyboard) | 4 000–6 500 | 1–2 |
| Black Shark 4/5 (Game buttons) | 3 500–5 000 | 1–3 |
| Redmi Note 9/10 (touch buttons) | 1 200–2 000 | 1 |
| POCO F3/F4 | 1 500–2 500 | 1–2 |
Before you give your phone away, ask the workshop to show you the original part (if promised), often under the guise of "original" sell Chinese replicas of poor quality, and also check if they will maintain waterproof (if the model has IP53/IP68 protection).
Independent keyboard replacement: step-by-step instructions
If you decide to change the keyboard (buttons, touch module) yourself, you will need:
- 🔨 Tools: plastic shoulder blades, tweezers, screwdriver PH00 or T3, glue-dryer.
- 📦 Parts: original keyboard module (you can buy on AliExpress, eBay or in specialty stores such as Fixez).
- 🧲 Additional: magnetic screw mat, antistatic bracelet, glue B-7000 plume-fix.
The replacement process depends on the model. Consider the general algorithm for the Xiaomi Mi Mix 3 with a retractable keyboard:
Turn off your smartphone and remove it. SIM-map|Backup the data (in case of memory damage)|Prepare the workplace: clean surface, good lighting|Check that the battery is at least 50% charged (for post-repair testing)-->
- Remove the back cover by swiping it with a plastic blade at the charging socket. Be careful, the Mi Mix 3 has a lid glued, so it needs to be warmed up with a hair dryer (~60°C).
- Unscrew all the screws that hold the metal plate over the battery. Use the magnetic holder to keep them from losing them.
- Unplug the battery plume to avoid short circuits, so put a plastic blade on the black connector.
- Find the keyboard module (usually located under the battery or next to the motherboard) and unplug its plume and remove the old part.
- Install a new module, plug in the plume, and assemble the phone in reverse order. Before final assembly, check the performance of the buttons.
Critical: On waterproof models (such as the Xiaomi 12 Pro), after disassembly, you need to replace the rubber seals and apply a new glue around the perimeter of the lid.

Frequent Keyboard Replacement Mistakes and How to Avoid Them
Even experienced craftsmen sometimes make mistakes that lead to additional breakdowns.

- If the keyboard is soldered (as on Black Shark), use a soldering station with a temperature not higher than 300 ° C. Overheating can cause the chips to fail.
- Misassembly. Forgotten screws or loosely screwed metal plates can cause skewed housing and damage to the display. Always check photos of the disassembly process.
- Ignoring water protection: On IP68 models (such as the Xiaomi 13 Pro), after disassembling, be sure to apply new glue and check the seals, otherwise the phone will lose water protection.
To minimize the risks, follow these tips:
- 📸 Take a picture of each step of the disassembly, which will help you to properly assemble the phone back.
- 🔋 Use an antistatic bracelet. Static electricity can damage the motherboard.
- 🧴 Apply the glue point-by-point. B-7000 It can get on the contacts and cause a short circuit.
💡
If the smartphone doesn't turn on after you change the keyboard, check the sequence of the plumes. Often the problem lies in the disconnected display or battery connector, not in the keyboard itself.
Comparison of options: official service vs workshop vs DIY
To choose the best way to replace the keyboard, compare all options on key parameters:
| Criteria | Official service | Third-party workshop | Self-sustaining replacement |
|---|---|---|---|

What to do if the keyboard does not work after replacement
If the buttons do not respond or work properly after repair, follow these steps:
- Check the plume connection. Open the phone and make sure the keyboard connector is tightly seated in the socket on the motherboard.

- Reset. If the problem is software, resetting to factory settings (Settings → Additional → Restore and Reset) will help. Remember to backup!
- Check the part on another device. If possible, connect the module to a known working phone of the same model.
If nothing helps, the problem may be:
- 🔌 Damaged connector on the motherboard (needs soldering).
- 🔋 Faulty keyboard controller (chip replacement required).
- 📱 Software failure (will help flashing through Fastboot).
In difficult cases, it is better to consult a specialist, for example, repairing the connector on the board will cost 2,000-4000. ₽, It’s cheaper than buying a new phone.
