A broken lock button on Xiaomi is a problem that owners of the brand's smartphones face, regardless of model, and it can stop working after a fall, when water gets in, or just wear out over time. But how much does it cost to replace it in 2026? The answer depends on three key factors: the phone model, the type of breakdown, and the repair site.
Many users try to deal with the problem on their own first — for example, turn on the screen through AssistiveTouch (in the settings of Special Opportunity → Ease of Control). However, this is a temporary solution: without a physical button, you can not restart the phone in emergency mode or confirm critical actions. And in some models (for example, Xiaomi 13 Pro or Redmi Note 12 Pro+), a non-working button blocks access to the Fastboot — which makes it difficult to firmware or reset settings.
In this article, we will examine:
- 📱 Replacement costs for different models – from budget Redmi to flagships Mi/Mix
- 🔧 Where is cheaper: in the service center, at private masters or with their own hands
- ⚠️ The Hidden Risks of Cheap Repairs (Why the Button May Break Again in a Month)
- 💡 Alternative solutions if repairs are too expensive
⚠️ Attention: 90% of the time, lock button sticking on Xiaomi is not due to mechanical failure, but to dust or contact oxidation. Before replacing, try to clean the button with an alcohol solution (instruction below).₽.
1.Prices for the replacement of the lock button in 2026
The cost of repairs varies from 800 to 3500 rubles depending on the model and type of service. Below are the current prices for popular Xiaomi devices (data collected by Moscow and regional service centers):
| Smartphone model | Cost of replacement (₽) | Notes |
|---|---|---|
| Redmi 9A / 10A / 12C | 800–1200 | Budget models with a simple button design |
| Redmi Note 10 / 11 / 12 | 1200–1800 | Requires a mid-level breakdown of complexity |
| POCO X3 / X4 / X5 | 1500–2200 | Often breaks after falls due to fragile fastening |
| Xiaomi 11T / 12T | 2000–2800 | Complex disassembly, risk of damage to the display plume |
| Xiaomi 13 / 13 Pro / 14 | 2500–3500 | Flagships with IP68 protection – sealing after repair is required |
Prices are for work + parts. In official Xiaomi service centers (for example, Mi Service), the cost can be 20-30% higher, but they give a guarantee of up to 6 months. Private workshops often offer cheaper, but the risk of running into a poor-quality button or damage to the case is higher.
Important: In models with water protection (IP53/IP68) After the lock button is replaced, leakage is lost. To restore protection, additional squeezing of the body will be required (from the lock button to the lock). +500₽).
2. Why the lock button breaks: top-5 cause
Xiaomi's Power button fails more often than other controls, here are the main reasons:
- 💦 Even if the phone is not sinking, condensation or high humidity oxidize the contacts. Unprotected models are particularly vulnerable (Redmi 9, POCO M3).
- 🤳 Mechanical damage. Impacts on a hard surface displace the mechanism of the button, often when you fall on the corner of the body.
- 🔋 Wearing the machinery. 2–3 In the years of active use, the plastic parts of the buttons are erased (typical for Redmi Note). 8/9).
- 🧹 Dust pollution, and dirt gets under the button through the microslits, blocking it from moving.
- ⚡ Firmware is wrong. Rarely, but it happens: after a failed update MIUI button ceases to respond to pressing (solved by resetting settings).
If the button is not pressed at all, the problem is more mechanical: if it is pressed, but it does not work, it is the plume or oxidation of contacts, in the latter case, sometimes disassembling and cleaning with isopropyl alcohol (90%+).

3. Self-Substitution vs. Service: Which is Cheaper?
Many users are considering replacing the button with their own hands. Let's compare the costs:
- 🔧 Self-Defense: Lock button (AliExpress/Avio) — 200–600₽ Set of screwdrivers (if not) — 300–800₽ Suction suction cups — 150–300₽ The risk of damaging a display plume or battery is priceless
- 🏢 Service center: Cost of work - 600-2000₽ (Original/Quality button – included in the price Warranty – 1 to 6 months
At first glance, self-replacement is cheaper, but there are pitfalls:
⚠️ Attention: In 40% of cases, when you disassemble Xiaomi yourself, users damage the display plume or tear off the contacts of the battery, repairing these consequences costs 3,000-8000₽ — More expensive than the original button replacement.
If you decide to repair yourself, here is the minimum set of tools:
Buy a new button (check compatibility with the model)|Buying a plastic spatula for disassembly|Prepare tweezers and screwdrivers T3/T4/T5|Download the Disassembly Guide for Your Model (YouTube/4PDA)|Turn off the phone and take it out. SIM-pre-work-card-->
4. Where to replace the lock button: comparison of options
The choice of the repair site depends on the budget, time and quality requirements.
| Type of service | Pluses | Cons | Average price (₽) |
|---|---|---|---|
| Official Xiaomi service | 6 months warranty, original spare parts | Expensive, long (3-7 days) | 2000–3500 |
| Authorized partners | 3 months warranty, prices below official | They can use unoriginal parts. | 1500–2800 |
| Private workshops | Cheap, fast (1-2 hours) | No guarantee, risk of poor quality repairs | 800–2000 |
| Independently. | Minimum costs | High risk of damage, no guarantee | 500–1500 |
For models with water protection (Xiaomi 13/14, Redmi Note 12 Pro+), we recommend the official service - there after repair restore tightness. For budget smartphones (Redmi 10A, POCO M5) fits a proven private workshop.
💡
Before choosing a service, check reviews on Yandex.Maps or 2GIS. Pay attention to complaints about “repeated breakdowns” – this is a sign of using cheap Chinese buttons that fail in 1-2 months.
5 How to use your phone temporarily without a lock button
If repairs are delayed and the button is not working, there are several ways to unlock and control your phone:
- 📱 AssistiveTouch (Virtual Button): Go to Settings → Special capabilities → Management convenience → AssistiveTouch. Turn on the function and add the lock button to the screen.

6. How to avoid breaking the lock button in the future
To make the Power button last longer, follow the simple rules:
- 🛡️ Use a case with reinforced edges - this will protect the button from impacts when falling.
- 🚿 Avoid moisture, even if the phone is protected. IP68, Do not put it to water (condensate still penetrates into the microslits).
- 🧼 Clean the button regularly. Rub it every 3-6 months with a cotton swab dipped in alcohol.
- 🔋 Don't push the button too hard. POCO Redmi mechanism often breaks due to rough pressing.
If you drop your phone frequently, consider touch-lock models (such as the Xiaomi Mix 4 or Redmi K60 Ultra) that are less vulnerable to mechanical damage.
💡
The most common reason a lock button breaks on Xiaomi is to fall on a hard surface, and even with a case, a hit on the corner of the case can displace the button mechanism, making it idle.
