Modern Xiaomi devices are famous for their reliability, but even the highest quality remote controls can fail. Most often, users are faced with sticking buttons, oxidizing contacts or damage to the body after a fall. In such situations, the acute question arises: can you disassemble the remote control to clean it or replace the power cells without damaging fragile electronics?
Unlike older TVs that used large screws, modern Xiaomi devices are often assembled on latches or hidden screws. Incorrect opening can cause plastic mounts to break, making further operation impossible, so it is crucial to know the exact sequence of actions and have the right tool on hand.
In this article, we will take a closer look at the process of dismantling various remote models, including the Mi Remote and Mi Box S. You will learn how to safely open the case, clean the contact areas of oxides and assemble the device back.
Necessary tools for safe autopsy
Before you start dismantling, you need to prepare the workplace and tools, and rushing is the enemy, because the plastic on Xiaomi remotes is quite thin and fragile. You'll need the minimum set that most home craftsmen have to work with.
The main tool will be a thin plastic card or a special mediator to open the cases. The use of metal objects such as knives or screwdrivers is strongly discouraged in the initial stages, as they can damage the internal plumes or scratch the front panel.
☑️ Disassembly tools
You'll also need:
- 🔧 Thin cross-sized screwdriver PH00 or PH000 screw-up.
- 🧤 Tweezers with antistatic coating for working with small details.
- 💧 Isopropyl alcohol or special contact cleaner for cleaning the board.
- 🔦 Lantern to inspect internal cavities for microcracks.
It's important to have good lighting. Any small detail that falls on the floor during the disassembly can make it impossible to put the remote back together. Prepare a screw folding container so that it doesn't get lost.
Determination of the type of attachment of the remote body
Xiaomi's remotes can be divided into two main types of remote controls, screw and latch. Understanding your model's design is 50 percent of the success of the operation. Misusing the force to screw will only cause the plastic to break.
Screw patterns are less common, mostly in older versions or dedicated remotes for the Mi Box. Carefully inspect the back cover. Sometimes screws hide under decorative stickers, rubber plugs, or even under the battery compartment. Use a magnifying glass to keep hidden mounts out.
Where to find hidden screws?
⚠️ Warning: Never force the halves of the body unless you're convinced there are no screws. Xiaomi plastic often has guides that break easily when skewed.
Latch models are the standard for the Mi Remote line, and they're assembled by ultrasonic welding or tight plastic latches around the perimeter, and in these cases, opening requires careful traversing throughout the circuit of the device, and it's important not to damage the plume that connects the buttons to the main board.
You can also tell the type of assembly from the sound, and if you can tap the body lightly, you can hear a rattling sound, you might already have a backlash inside, and you need to take care of it, and if you're a monolithic body, it's probably latches.
Step-by-step: how to open the remote on the latches
The process of opening the latch models requires patience. Start by detaching the back cover if it is removable. If the case is monolithic, insert a plastic card at the junction between the top and bottom of the case in the battery compartment.
Move slowly around the perimeter, turning the instrument slightly. You should hear the characteristic clicks of the opening latches. Don't try to open the remote on one side completely, you should go around in a circle, gradually increasing the gap.
| Phase | Action. | Risks. |
|---|---|---|
| Beginning. | Inserting the card in the seam | Damage the face panel. |
| Process | A roundabout | Break the latches |
| Finals. | Separation of halves | Break the plume. |
When all the latches are loosened, gently lift the top, and at that point, be very careful: there may be a thin plume inside that connects the buttons to the board, and a sudden movement may break the contacts, and then the remote will not respond to the presses.
💡
Use a smartphone screen suction cup to gently lift the top of the body after the latches are loosened, this minimizes the risk of plastic damage.
Disassembly of Xiaomi Mi Box remotes and old models
Mi Box consoles are often more complex in design. In some models, the screws can be located under the Mi logo or in recesses closed with rubber plugs. Use a thin stitch or needle to access them.
After all the visible screws have been twisted, the body can still be held on the internal guides, in which case you need to carefully walk the plastic blade along the side faces, pay special attention to the top of the remote, where the IR sensor or Bluetooth antenna is located.
Inside, you'll find a main board that can be attached with extra screws or just in the slots. If you have a Bluetooth remote, look for an antenna wire that can be glued to the inside of the case. Unplug it slowly so that you don't damage the insulation.
For voice-controlled models, there may be a microphone inside, and its membrane is very sensitive to dust and moisture, so when disassembling, try not to touch this assembly with your fingers. Fat spots can impair the quality of sound transmission.
Cleaning contacts and electronics maintenance
One of the main reasons for disassembly is cleaning the contacts, and over time, the graphite coating on the rubber buttons is erased, and the contacts on the board are oxidized, and to restore work, you need to carefully wipe the board with a cotton swab dipped in isopropyl alcohol.
Rubber buttons also require maintenance. Wash them with warm water with mild soap, dry them thoroughly and wipe them with alcohol. If the buttons stop working because of the erased graphite, you can use a special conductive lacquer or gently paste a piece of foil.
- 🧼 Carefully remove all dust and pile from the inner corners of the enclosure.
- 🔌 Check the integrity of the battery compartment, if necessary, buckle the contacts.
- 🔍 Check the fee for microcracks or detached elements.
💡
Quality cleaning of contacts with alcohol restores the remote in 80% of cases when there are problems with the response of buttons.
After cleaning, allow all components to dry completely. Even a minimal amount of moisture can cause a short circuit when installing batteries. It is better to wait 10-15 minutes in a well-ventilated room.
⚠️ Note: Do not use acetone or aggressive solvents to clean rubber buttons, as they can break the structure of the material and make the buttons sticky.
Remote assembly and functionality check
The assembly is done in reverse order. First, make sure that all the plumes and wires are packed into their channels and not be clamped with the body. When connecting the halves of the body, make sure that all the guides match.
If the model is screwed, twist the screws without excessive effort, so as not to break the thread in the plastic racks. For latch models, evenly press the perimeter until the characteristic click. Check if there are gaps between the parts of the case.
Set up the batteries and check all the buttons. Connect the remote to the TV or console. If a Bluetooth device might need to re-pair, this usually requires slamming a combination of buttons, like Home and Menu, at the same time.
What to do if the remote does not work?
If the remote is not working properly, you will have to repeat the disassembly procedure, most often the problem lies in a poorly inserted plume or oxidized contact that could not be cleaned the first time.
