A situation where urgent withdrawal is required SIM-A card from a smartphone, but a special key (ejector) is lost or never found, is familiar to many users of Xiaomi, Redmi and Poco. Usually this happens at the most inopportune moment: you need to change the operator, insert a memory card or simply clean the contacts of the tray from dust. A standard tool is a thin metal pin that is easily lost among household garbage or falls out of the box when first unpacking.
Fortunately, the design of trays in the Chinese brand devices involves the use of standard mechanisms that can be activated by a variety of other items. The main thing in this process is not to panic or use brute force that can damage the locking mechanism or the motherboard itself. In this guide, we will look at safe and effective ways to solve the problem.
Why the tray SIM-card won't open
Before looking for alternative tools, it's important to understand why a standard mechanism might not work even with a native paper clip. Often the problem is not lack of a key, but pollution or mechanical entanglement. Inside the ejector hole is a micro-switch that releases the spring when pressed. If pile, dust or oxidation enters the hole, the mechanism's course is blocked.
Sometimes users confuse the hole for SIM-Noise reduction cards, especially in models with triple cameras or specific locations, and tapping the microphone will do nothing but damage the sensitive membrane. In Xiaomi Mi and Redmi Note devices, the holes are usually located next to each other, so care is required.
If the smartphone has been used for several years and the card has been changed frequently, the spring mechanism may weaken or, conversely, rust from moisture, in which case a more accurate exposure or lubrication of contacts (special means, for example, WD-40 Contact Cleaner, but not conventional oil) will be required.
Suitable means of extraction
If you don't have a key, you'll find things in every home or office, and the basic requirement is that you have enough stiffness, a thin diameter, and no sharp sharpness that can break inside the case, and you'll find paper clips that need to be straightened beforehand.
Another great option is sewing needles. However, you need to be extremely careful with them: the needle's eye may be too thick and the tip too sharp. It is better to use an old, slightly dulled needle or to rub the tip against a stone / sandpaper so as not to scratch the inner walls. Thin cloves, cloves earrings or even toothpicks (although the latter may break).
⚠️ Warning: Never use ballpoint pens, matches or wooden toothpicks as your main lever.The tree can crumble inside the mechanism, and the plastic of the handle can melt or get stuck, requiring the smartphone to be disassembled at a service center.
In emergency cases, some users use a sharpened knife tip, but this is the riskiest method.The blade can slip and damage the screen or body. If you choose this path, make sure that the blade is thin (like a stationery knife) and you hold it strictly perpendicular to the hole.
Step-by-step instructions for safe extraction
The extraction process requires calmness and a firm hand. Turn off your smartphone first. Although modern Xiaomi devices support hot SIM replacement, power cuts will reduce the risk of short circuit if you accidentally hit contacts with a metal object, and will save data from damage.
Find the end of the smartphone where the elongated tray hole is located. Put the selected tool (such as a straightened paper clip) strictly perpendicular to the plane of the body. Don't try to insert it at an angle - this can bend the inner lever. Press confidently, but without fanaticism, until you feel a slight click and spring resistance.
☑️ Algorithm of action
Once the tray is extended a few millimeters, remove the tool and with your fingers gently pull the edge of the tray. Don't pull too hard if it's stuck - you better press it again. After extracting, wipe the contacts. SIM-soft dry cloth before re-installing.
Tool comparison: what is best to use
Not all tools are equally effective and safe, and below is a table that will help you choose the best option for your situation, assessing the risks and availability.
| Tool. | Rigidity | Risk of breakdown | Recommendation |
|---|---|---|---|
| Office paperclip | Tall. | Low. | Perfect. |
| Sewing needle | Very high. | Medium (acute) | It requires caution. |
| Carnation earring | Medium | Low. | Good alternative. |
| Toothpick | Low. | Tall (breaks) | Not recommended |
As you can see from the table, the metal paper clip remains the leader in a combination of factors: it is flexible enough not to break inside, and hard enough to press the mechanism. Gold or silver jewelry can scratch or deform, so their use is only justified as a last resort.
If you have a multitool at hand, it often has a special pin for SIM-It's a professional tool that guarantees safety, but it's not always comfortable to carry around, so it's suitable for home use.
What to do categorically can not be done
There are a number of actions that can turn a minor problem into an expensive repair: First, don't try to pick a tray with a knife or blade, inserting it into the gap between the tray and the body. You're almost guaranteed to damage the frame or, worse, the antenna plume if it passes nearby.
Risks of using glue
Second, avoid using objects that are too thick. If the tool doesn't enter the hole freely, don't push harder. You can roll the hole or break the plastic lock inside. Third, don't use magnets. They won't help pull the tray out, but they can have a negative impact on the Hall sensors or the dynamic speaker membrane.
⚠️ Attention: If the tray is not removed after a few careful attempts with different tools, it may be damaged or deformed. Further attempts may lead to breakage of the case.
What to do if the tray is stuck or broken
There are situations where the mechanism is stuck, and if you hear a click, but the tray is not moving out, maybe a spring has come off or the tray is skewed inside the body, in which case you can try to gently sway the tool from side to side (literally by a millimeter) to release the jammed part.
If a piece of tool (like the tip of a toothpick or a piece of needle) is left inside, it's almost impossible to extract it yourself indiscriminately. Trying to pick up the piece with tweezers often pushes the debris deeper, requiring the dismantling of the smartphone and access to the tray from the inside of the motherboard.
💡
To prevent jamming, wipe the tray once every six months. SIM-cards with an alcohol napkin and blow the hole with compressed air to remove dust and pile.
In cases of serious failure, when the tray is arched or the mechanism is destroyed, the only way out is to replace the tray. Fortunately, for the popular Xiaomi Redmi Note and Poco models, the new trays are inexpensive and easy to order on marketplaces.
💡
The most important rule is to act without haste and without excessive effort. SIM-The cards are miniature and the power is not needed, it is necessary to be precise.
Where to get the original key or replacement
If you lose the key and don't want to risk it, you can buy it. Original ejectors are often in boxes from old friends' or colleagues' phones, because few people throw them away right away, and you can buy them from electronics stores, communication stores, or online.
The cost of a key is minimal, often sold in sets of 5-10 pieces, it's a smart investment to have a spare tool in your wallet or keyboard, and many service centers can give you a key if you just go in and ask for it, which is a consumable that doesn't represent much value to the seller.
Remember that tray extraction holes are standardized for most modern smartphones.The key from Samsung, iPhone or Huawei will fit your Xiaomi without any problems.So if you have a box from another gadget, check the parts there.
