Replacement of the lock button on Xiaomi: current prices and expert advice

Owners of Xiaomi, Redmi and POCO smartphones often face situations where the usual unlock mechanism stops responding to presses or starts to stick.This is a critical problem, since the lock button is used not only to turn on the screen, but also to call the power menu, activate the voice assistant and even reboot the device in the event of a freeze. Ignoring a malfunction can lead to a complete discharge of the battery if the phone cannot be turned off in the standard way.

The cost of repairs varies widely and depends on many factors, which we will discuss in detail below. Xiaomi uses different types of terminals and plumes depending on the series of devices, which directly affects the price of the spare part. In this article, you will find the current price, comparing the cost of original components and analogues, and also understand when it is better to replace the button and when it is easier to buy a new phone.

Many users mistakenly believe that the problem lies solely in the software failure, and spend hours resetting settings, while the physical wear of the button mechanism has already reached a critical point. Understanding the real cost of replacing will help you make an informed decision and not overpay for unnecessary diagnostic procedures in service centers.

What the final repair price depends on

The final check forming process is nonlinear. The base cost is made up of the price of the spare part and the work of the master, but there are nuances that can double or lower costs. The first and foremost factor is the model of your smartphone. The flagship Xiaomi Mi and Xiaomi 11/12/13/14 series often have more complex design solutions where the button can be integrated into the charging port plume or side bezels, which makes disassembly more difficult.

The second important aspect is the type of part used: there are three main options on the market: original components (OEM), quality compatible counterparts and budget copies. The original button guarantees factory speed and tactile sensation, but costs more. Analogs can serve as well, but their press cycle life is often lower. Budget options tend to fail after a few months.

The cost of repairs in an authorized center will always cost more than in a private workshop at home, but it guarantees the preservation of moisture protection (if any) and the use of certified materials. In remote regions, the cost of logistics of spare parts can add up to 30% to the total amount.

• 📱 Model of the device: from budget Redmi to top Xiaomi.
• 🔧 Type of spare part: original, OEM-analogue.
• 🏙️ Geography: prices in Moscow and St. Petersburg are higher than in the regions.
• ⏱️ Urgent: Express repairs for 30 it costs a minute 20-30% more.

Average replacement prices in service centers

Analysis of the mobile repair market this year shows a clear price gradation: In the budget segment, which includes the popular Redmi Note and Redmi series (digital series), the cost of replacing is the cheapest.

For mid-range smartphones like the Redmi Note Pro or POCO X series, the cost increases, due to the tighter layout of internal elements and the use of more expensive plumes, where the masters often recommend changing the entire bottom plume (sub-board), where the button is soldered, to eliminate the risk of oxidation of contacts in the future.

Flagship models, including the Xiaomi Mi and Xiaomi T series, require the most investment, often combined with the volume buttons in a single side frame module or part of a complex plume, in which cases replacing the button may require a complete disassembly of the device, removal of the battery and display, which significantly increases the cost of work.

💡

When ordering services from the service, always check whether the cost of the diagnosis is included. Often, if you agree to the repair, the diagnosis is free, but if you refuse to repair, you can charge a separate fee for it.

The cost of original parts against analogues

Choosing between the original and the analogue is a perpetual dilemma when repairing equipment. The original part from Xiaomi is labeled by the manufacturer and undergoes strict quality control. It usually lasts from 50,000 to 100,000 taps. It is harder to find such parts and they cost significantly more, sometimes up to 70% of the cost of repair.

High Copys are made in the same factories as the originals, but without the brand. They may not have a logo, but they are almost the same in functionality and tactile sensations. The price difference can be doubled. For most users, this is the most rational choice in terms of price-life ratio.

Cheap Chinese analogues without a brand name are lottery games, which can last a year, or they can fail in a week. Metal in such buttons is often soft and quickly deformed, which leads to re-sticking. The savings of 200-300 rubles here do not justify the risk of re-entry into the service.

⚠️ Warning: If the master insists on buying only original parts for an old smartphone (for example, Redmi Note 8 or older), this may be an attempt to increase the check.

Can I replace the button myself?

In theory, replacing the lock button with Xiaomi is available at home, but in practice it depends on the model of the device. If you have a budget smartphone with a plastic back cover and a separate button module, the process can take 20-30 minutes with a thin screwdriver and mediators. However, in modern models with glass cases and moisture protection, the risk of damage to other components increases many times.

To repair yourself, you’ll need a special set of tools, including a suction cup, thin blades, tweezers and perhaps a thermophen or heating pad to gently unstick the back cover. Self-replacement without experience often results in damage to the display or battery plumes, turning a minor repair into a major financial loss.

If you still decide to take independent actions, be sure to find the exact instruction (teardown) for your model on YouTube or specialized forums. There are no universal instructions, since the location of the plumes and screws in each Xiaomi is unique.

• 🛠️ Tools: Set of screwdrivers, mediators, sucker, tweezers.
• 🔋 Safety: Be sure to turn off the battery before work begins.
• 🎥 Instructions: Watch the video disassembly specifically your model.
• 🧩 Part: Buy a button in advance with spare screws and glue.

Interim solutions and software crutches

If you can't pay for a repair right now, and you need a phone in the middle of nowhere, you can use software to get around the problem. Android, and in the MIUI shell in particular, there are features that minimize the use of a physical button, and that won't solve the problem completely, but it will help you to get to the service.

The first and most effective way is to activate the Double Touch to Turn on feature, which allows you to wake the screen with your finger tapping on the display, and you can find this option by going to Settings → Always On Screen and Lock Screen → Double Touch to Turn on. This takes the load off the mechanical button every time you use the phone.

The second life hack is using a virtual button or gestures. In navigation settings, select gesture control so you don't use buttons at the bottom of the screen that might conflict with system commands. You can also set up automatic on/off schedules so you don't depend on the power button to reboot.

⚠️ Attention: Software crutches do not help if the button closes the contacts inside, causing random screen switching or interface dancing, in which case only the physical deactivation of the button plume inside the phone, if the design allows it, will help.

💡

Software settings can extend the life of a phone with a faulty button by several weeks, but do not eliminate the risk of a complete device failure or battery bloating due to the inability to turn off.
