How to change the keyboard on Xiaomi Redmi Note 10S: a detailed guide with photos

Introduction: When you need to replace the keyboard with the Redmi Note 10S

Keyboard (or, as it is often called, touchscreen with a digitizer) is one of the most vulnerable elements of the Xiaomi Redmi Note 10S. Falling from a height, a strong impact or even a banal ingress of moisture can make it out of order. If the screen stopped responding to touch, displays artifacts or does not turn on at all, while the display itself glows — the problem is in the touch module.

In service centers, it costs between 3,000 and 6,000 rubles to replace a keyboard, but with tools and patience, you can do it yourself. The main thing is to choose the right part, carefully disassemble the phone and not damage the plumes. In this article, we will discuss the entire process from A to Z, including nuances that are often not mentioned in short video instructions.

Note: The Redmi Note 10S (model number M2101K7BI) has a unique screen design that is incompatible with other Note 10 series models. Using a non-original keyboard can lead to calibration or display problems.

Signs of a Keyboard Failure: How to Diagnose a Problem

Before you start replacing, make sure that the sensor module is to blame, not software failure or damage to the motherboard.

• 📵 The screen does not respond to touch (in whole or in part).
• 🌀 Self-pressing ("ghost taps") without your involvement.
• 🎨 Color distortion or vertical/horizontal stripes when pressed.
• 🔄 The sensor only works after the phone is rebooted or heated.
• 💧 Traces of oxidation under glass (visible in bright light at an angle).

If the screen doesn't turn on at all, the problem may be in the display plume or the power controller, in which case a comprehensive diagnostic is required.

1. Connect the phone to your PC and check if it is defined as an input device (in Windows Device Manager).
2. Run the sensor test through the engineering menu: type ##6484## → Touch Test.
3. Try connecting the mouse over OTG – if the cursor moves and the touches don’t work, the sensor is to blame.

⚠️ Warning: If the phone falls into water, do not turn it on until it is completely dry (minimum 48 hours in rice or silica gel.

Selection of a new keyboard: original vs. analog

Part quality is responsible for 80% of repair success, and there are three types of keyboards available for the Redmi Note 10S:

Where to buy:

• 🛒 Xiaomi’s official service centers are originals only, but high price.
• 🌍 AliExpress – Look for sellers with a 98 rating%+ and reviews in the photo (example: M2101K7BI Touch Panel).
• 🏢 Local repair shops – often sell used originals after replacement.

Critically, check the compatibility with the phone model (M2101K7BI) and screen version (IPS LCD, 6.43, 90Hz).Some vendors will slip parts from the Redmi Note 10 Pro or POCO X3 Pro - they won't fit!

💡

Before buying, ask the seller for a photo of the keyboard plume - it must match your (24-pin connector with gold contacts).

Required tools for replacement

To disassemble the Redmi Note 10S and replace the keyboard, you will need:

Screen suction cup (∅ 5-7 cm)|Plastic mediators (0.1–0.2 mm)|Screwdriver. T3 and T5 (magnetic)|Tweezers with curved ends|Dryer or thermo-air station (up to 80)°C)|Double-sided scotch (3M 9448A analogue)|Isopropyl alcohol (90%+)|Loupe or magnifying glass-->

Why are these tools:

• 🧲 Magnetic screwdrivers will prevent the fallout of screws during disassembly.
• 🔥 A hair dryer is needed to soften the glue under the screen (temperature not higher than 80).°C, otherwise damage the display!).
• 📏 0.1 mm mediators are thinner than standard 0.2 mm and less risk of damaging plumes.
• 🧴 Isopropyl alcohol removes glue residues without traces (unlike acetone).

If you don't have a thermal air station, you can use a household hair dryer at a minimum power, keeping it at a distance of 10-15 cm from the screen. Under no circumstances use a building hair dryer - it will overheat the display and spoil the polarization layer.

⚠️ Attention: Screws in the Redmi Note 10S They are of different lengths (3 mm and 5 mm) and if you confuse them when you build them, you risk damaging the motherboard or battery.

Step-by-step instructions for replacing the keyboard

The replacement process will take 1.5-2 hours. Follow the instructions strictly in order:

1.Switching off and preparing the phone

Turn off the Redmi Note. 10S, extract SIM-If the battery is swelling, don't keep disassembling, call the service. Lower the phone to 20 to 30 percent for safety.

Heating and removal of the back cover

Dryer warm up the edges of the back cover around the perimeter for 2-3 minutes. Carefully tuck it in with a plastic mediator, starting at the corners. In the Redmi Note 10S, the lid is mounted on latches and double-sided tape - do not apply excessive force.

3. Battery shutdown

When you remove the lid, the first thing you do is unplug the battery plume (marked BAT connector). Use a plastic mediator to gently lift the connector. Don't pull the wires!

4. Dismantling of motherboard

Unscrew all the screws (12 pieces) and gently raise the fee, starting at the top edge.

• 🔌 Camera plumes and speakers - they are fragile and easily torn.
• 📶 Antenna contacts – do not bend them when raising the fee.

5. Keyboard replacement

Disconnect the plume of the old keyboard (connector) TP_CONN Dry dryer the edge of the screen and carefully separate it with mediators. Remove the glue residue with alcohol. Install a new keyboard, making sure that the plume is not twisted.

Use a new double-sided tape (e.g. 3M 9448A) to fix the screen evenly across the area, avoiding bubbles.

Assembly and inspection

Put the phone back together.

1. Check the response to touch in the Settings menu → Display → Touch Test.
2. Make sure there are no dead zones on the edges of the screen.
3. Test your gestures (swipes, multi-touch).

💡

If the sensor is mirrored or offset after replacement, calibration is required via the engineering menu (code ##6484## → Manual Calibration).

Frequent Mistakes and How to Avoid Them

Even experienced keyboard designers sometimes make mistakes when replacing keyboards.

Another common problem is the touchscreen that's broken after assembly.

• 🔌 Unconnected or damaged plume (check connector) TP_CONN).
• 🔋 Faulty battery (if the phone turns off when you press the screen).
• 📱 Firmware failure (solved by resetting to factory settings).

If the screen is less sensitive after the replacement, try:

1. Calibrate the sensor through the engineering menu.
2. Update the firmware to the latest version of MIUI.
3. Check the settings in Settings → Additional → Touch buttons.

Calibration of the sensor after replacement

A new keyboard may require customization, especially if it's not an original part.

1. Enter the engineering code: ##6484##.
2. Select Manual Calibration.
3. Follow the instructions on the screen (usually touch the crosses in the corners and center).
4. Save the settings and restart the phone.

If there is no calibration option in the engineering menu, use third-party apps:

• 📱 Touchscreen Calibration (available on Google Play).
• 🖥️ MTK Engineering Mode (for phones with MediaTek processor).

After calibration, check:

• 🎯 Accuracy of presses (open the keyboard and click on the letters).
• 🔄 Swipe smoothness (scrolling lists, zoom in the gallery).
• ⏱️ Delayed response (in games or in fast typing).

⚠️ Warning: If the sensor gets worse after calibration (for example, clicks are recorded with a bias), reset to factory settings. In rare cases, flashing the phone through Fastboot helps.
