Owning a modern Smart TV from Xiaomi opens up access to a huge amount of entertainment content, but sometimes interaction with the device is disrupted due to problems with the remote control. If the buttons no longer respond to presses, stick or the device requires replacing batteries that cannot be removed in the usual way, there is a need to disassemble the case. Unlike cheap counterparts, Xiaomi remotes often have a hidden fastener and a monolithic design, which requires a special approach.
Self-opening not only replaces CR2032 batteries in some Bluetooth remote models, but also cleans contacts of oxides or spilled liquid, especially for Mi TV Stick and Mi Box owners, where the remotes are made in the form factor of sticks or have non-standard battery compartments.
In this article, we will take a detailed look at the algorithm for the different types of Xiaomi Mi Remote remotes. We will analyze the tools you will need for a safe opening, describe the intricacies of working with Bluetooth modules and IR emitters, and give you build tips. It is important to understand that any interference with the design of the device is at your risk, so follow the instructions as carefully as possible.
Before you start active, you need to determine the type of remote. Xiaomi devices are divided into infrared models (operated over an infrared port) and Bluetooth versions (required pairings). The design of their housings can be significantly different: some are assembled on screws hidden under stickers, others are exclusively on plastic latches that require the use of thin tools for opening.
Necessary tools for safe autopsy
To disassemble electronics properly, it is not enough to simply slash the body with a knife, as this is guaranteed to lead to scratches and chips. You will need a set of specialized tools that minimize the risks of damage to external plastic. The main tool is a set of plastic blades (spooders) or a mediator that does not conduct current and leave no traces on glossy surfaces.
If your Xiaomi remote is screwed, you'll need a precision screwdriver. Most often, Xiaomi's technology uses T5 or T6 (Torx) head screws, less often cross-mounted PH00s. Using an inappropriate size or type of screwdriver can lead to the slicing of the faces of the screw cap, after which it will be extremely difficult to extract it without drilling.
- 🛠️ A set of plastic blades or a mediator for neat opening of the body without scratches.
- 🔧 Precision screwdriver with bits Torx (star) and Phillips (cross).
- 🧤 Antistatic gloves to protect electronics from static electricity.
- 💡 A flashlight or lamp with good light to illuminate the internal components.
It is also recommended to prepare tweezers with curved ends, it is useful for extracting small screws from deep wells and working with plumes, it is also not superfluous to have isopropyl alcohol and a soft brush at hand if the purpose of dismantling is to clean contacts from contamination.
💡
Use a magnetic mat or a small screw folding capacity.The screws in Xiaomi remotes can be of different lengths, and it is important not to confuse them when assembled so as not to damage the thread in the plastic.
Determination of the type of fastening and preparation of the workplace
The first step in any disassembly is a visual inspection of the device. Xiaomi remotes often have a very smooth body with no visible screw holes. Carefully inspect the back cover of the battery compartment. If there are no screws under the removable panel, then the body is assembled on hidden latches or screws are disguised under decorative stickers or rubber legs.
Pay special attention to the bottom of the remote and the area around the Mi logo. In some models, the screws can be hidden under a thin layer of glue or stubs that need to be carefully removed by the needle. Incorrectly determining the type of attachment can lead to a break in the body when you try to push the halves apart by force. If the remote does not open with a light effort, then you missed some mounting element.
⚠️ Note: Do not use metal objects (knives, screwdrivers) for the initial opening of the case. Metal can damage the internal plumes or close contacts on the board if the remote was not completely de-energized.
Prepare the workspace: cover the desk with white paper or cloth, so you don't lose any small details and you can see if a cog rolls out of the work area, light should fall on the side or in the front so that the shadows can help you see the relief and joints of the plastic parts, make sure that the room is not drafts that can carry light elements.
☑️ Preparation for disassembly
Step-by-step: disassembly of a standard IR panel
Consider the process of disassembling Xiaomi's most common IR remote. If screws are missing, start opening from the bottom end of the device, where the hole for the dark man is usually located, or just the junction of the halves. Put a plastic blade in the gap between the top and bottom of the case. Move the blade along the perimeter, carefully snapping plastic clips.
Go around in a circle without trying to open one side completely. Your job is to loosen the latches evenly around the perimeter. When you hear the characteristic click, it means that one of the latches is free. Continue to go around the circuit until the body begins to diverge. If the resistance is too high, check again for hidden screws.
When you remove the back cover, you'll have access to a PCB. Xiaomi's IR panels often use AAA batteries mounted in the holders. Some models need to unscrew the board or gently raise it. Be careful with contact springs, they can be soldered to the board or simply inserted into plastic.
- 🔍 Carefully inspect the charge for oxides or cut off contacts.
- 🧼 If necessary, clean rubber buttons and board with alcohol.
- 🔋 Check the polarity of the battery before assembly.
If you find a board with a Bluetooth module inside, be even more careful. Antenna wire (if it's in the form of a wire) can be glued to the body. A sudden movement can cause the antenna to tear off, which will reduce the range of the remote. Carefully disconnect all visible connections before fully removing the board.

Disassembly of Bluetooth-based remotes and pointing consoles
Xiaomi Bluetooth remotes, often bundled with Mi Box S consoles or Mi TVs, are more complex in design, including a battery or battery-pill, and a wireless communication module, often starting with the removal of a battery compartment that can be combined with the back cover.
In some models, such as the remote-spec, the screws can be under a removable plug at the bottom. Use a thin needle to plug the plug. After the screws are twisted, the body may not open immediately, since the halves are often sealed with adhesives to keep tight, in which case it helps to carefully warm up the hairdryer (without overheating!) or use a thin blade.
Inside, you'll see a green board with a black droplet (chip) or a full-fledged module. Pay attention to the battery connector if it's lithium. Before disconnecting the contacts, make sure you don't lock the plus and minus with a tool. Bluetooth remotes often have a problem with button contacts oxidation that can be solved by cleaning.
| Type of remote | Location of screws | Type of battery | Difficulty disassembling |
|---|---|---|---|
| Standard IR | Under the back cover. | AAA (2 units) | Low. |
| Bluetooth (Mi Remote) | Hidden/Stubby | AAA or battery | Medium |
| Remote-guided | Inside the battery bay | CR2032/Lithium | Tall. |
| Voice remote | No (latch + glue) | Built-in Li-Ion | Tall. |
When working with Bluetooth modules, it is important not to damage the quartz resonator, a small metal element that is responsible for frequency stability, it is very fragile and when hitting a hard surface, it can lose its leakage or split, which will lead to unstable operation of the remote.
💡
The main feature of Xiaomi Bluetooth remotes is the presence of hidden screws under decorative elements and the use of glue to fix the halves of the body, which requires accuracy when opening.
Cleaning contacts and maintaining internal electronics
One of the main reasons for disassembling the remote is the need to clean. Over time, dust, grease and oxides accumulate between the graphite contacts on the rubber pad and the paths on the board, which causes the remote to become dull or require a strong press. Use a cotton swab dipped in isopropyl alcohol to clean.
Carefully wipe the board at the contact locations. Do not use water or aggressive solvents such as acetone, as they can wash away the labeling or damage the plastic elements of the board. After cleaning, let the alcohol completely evaporate before assembly. A wet board can cause a short circuit.
If the graphite coating on the rubber bands has worn off, you can use a special conductive lacquer or even gently rub the contacts with soft graphite (for example, a 4B pencil, although this is a temporary solution), however, for long-term repairs, it is better to purchase a new rubber button block if you can find it on sale for your model.
- 🧽 Use only lilaless wipes or cotton swabs.
- 💧 Isopropyl alcohol evaporates quickly and leaves no traces.
- ⚠️ Avoid getting liquid under buttons and in the gaps of the board.
Also check the IR emitter (the LED at the top of the remote) and it needs to be securely secured, and if it's hanging around, you can gently attach it with a drop of glue, but make sure that the glue doesn't hit the transparent window of the emitter, otherwise the signal will get weaker.
Assembly of the device and check of performance
The assembly is done in reverse order. First, make sure all the plumes and connectors are connected correctly and before clicking. When you put the board in the case, make sure that the wires are not clamped with plastic parts. This is especially important for antenna wires in Bluetooth remotes.
As you connect the halves of the body, start on one side and slowly snap around the perimeter. You should hear clear clicks. If the body doesn't fit, don't push, check if the screw has hit the screw or if the plastic lock has crooked. Forced assembly can lead to cracks.
⚠️ Warning: When assembly, make sure that no wire is pressed with the housing lid. Vibration when using the remote can wipe the insulation of the wire, which will lead to short circuit and the remote will fail.
Once assembled, insert the power and check all the buttons. Point your smartphone camera at the top end of the remote and press any button. If you see flashes of purple or white light on your phone screen, the IR port is working. The Bluetooth remote will require an attempt to pair with the TV.
