How to open the compartment for SIM-Xiaomi cards without a key: all working methods

Stuck with a blocked tray SIM-The situation is familiar to many: the key is lost at the most inopportune moment - when moving, changing the operator or buying a used phone. Fortunately, there are alternative ways to extract the tray without risking damaging the smartphone if you act carefully.

In this article, we will analyze 7 proven methods - from improvised tools (clips, needles) to software solutions for modern Xiaomi models (including Redmi Note 12, POCO X5, Mi 11 et al., and we'll focus on safety, which actions can cause the connector to break or debris to get inside the case, and you'll also learn what to do if the tray gets stuck after a failed attempt to extract it.

We warn you right away: none of the methods guarantee 100% success, but if executed correctly, the risks are minimal.If you own a flagship model (for example, Xiaomi 13 Ultra), it is better to contact a service center - their trays are often equipped with additional protection against hacking.

Why you can't open the tray SIM keyless?

Xiaomi manufacturers (like other brands) specifically make it difficult to access the slot for the game. SIM-cards for several reasons:

• 🔒 Protection against theft: without a key, it is more difficult for an attacker to extract SIM-Card and lock the phone through the operator.
• 🛡️ Damage prevention: improper extraction can bend tray contacts or break the locking mechanism.
• 🌧️ Tightness: in models with protection IP53/IP68 (for example, Xiaomi 12S Ultra) loose tray fit reduces water and dust protection.

Structurally, the tray is held by a tiny spring mechanism, and the key presses on that spring, releasing the latch, and without it, you have to create a similar force point-by-point and without distortion, otherwise you risk jamming the tray forever.

⚠️ Note: If your Xiaomi is guaranteed, self-opening the tray can cancel it. Official service centers use special tools that leave no trace.

Method 1: Paperclip or stationery button - the classic method

The most common and safe option is to use an open clip or a stationery button, which is suitable for 90% of Xiaomi models, including budget Redmi and mid-range (POCO F4, Mi 10T).

Step-by-step:

1. Take a medium-sized paperclip (not too thin) and unwind it so that a straight segment is long. ~3-4 cm.
2. Insert the end of the paper clip into the hole next to the tray SIM-It is located on the end of the body (usually on the upper or lateral face).
3. Press strictly perpendicular to the body until you feel a click.
4. The tray will extend 1-2 mm - pull it with your fingers to the end.

If the paper clip does not enter the hole:

• 🔍 Check if the hole is clogged with dust (relevant for older phones).
• 📏 Make sure the diameter of the paper clip is less than 0.8 mm (standard for keys Xiaomi).

This method works even for dual-slot models (Xiaomi 11 Lite). NE 5G), But it requires more effort because of the reinforced spring.

Method 2: Needle or pin for thin holes

If the turnkey hole is too narrow (relevant for Xiaomi Mi) A3, Redmi 9A), The paper clip may not fit:

• 🪡 Sewing needle (better with an ear - it will not let it fall inside).
• 📍 English pin (preliminary bite off the ball with cutters).
• 🖋️ The rod from the gel handle (if the diameter is suitable).

Important: the needle must be metallic and straight, and the plastic or rusty needles break down and stay inside the case.

Implementation technique:

1. Hold the needle in your fingers so that it does not bend when pressed.
2. Then put it in the hole and put it in the snare.
3. Once the tray has moved, stop the pressure and pull it with your hands.

⚠️ Warning: Do not use toothpicks or wooden sticks - they crumble and clog the mechanism. Also avoid knives or scissors: their blades can scratch the body or damage the seal (in waterproof models).

Method 3: Software extraction of the tray (for new models)

Modern Xiaomi smartphones on the basis MIUI 13/14 (for example, Xiaomi 12 Pro, POCO F5) Support software management of the tray SIM It's a simple, simple, mechanically-intensive process, but it doesn't work on all firmware.

Instructions:

1. Open the Phone app and dial the combination: ##4636## (some models may require ##3644633##).
2. In the menu that appears, select Phone Information → Choose. SIM-map.
3. Click on the Extract option. SIM-card (if active).
4. The tray will be pushed out automatically in 5-10 seconds.

If the menu does not open:

• 🔄 Reboot your phone and re-enter the code.
• 📱 Check the version. MIUI In Settings → The phone. It works on 12.5.+.
• 🔓 Make sure there is no lock from the operator on the phone (for example, if the device is purchased on credit).

Method 4: Tape or Scotch – if the tray is not fully extended

Sometimes the tray shifts by 1-2 mm, but does not go out to the end, in which case, bilateral tape or tape will help:

1. Cut a strip of scotch 3-4 mm wide and long ~5cm.
2. Stick it with a sticky side down to the edge of the tray (where it sticks out of the body).
3. Carefully pull the loose end of the scotch parallel to the body, without jerking.

Alternatively, use a plastic card (bank or discount):

• 💳 Insert the map between the case and the tray at the place of the gap.
• 🔄 Shake it left-right until the tray comes out.

💡

If the tray is stuck after the phone falls, do not try to pull it out by force. First, check if the contacts are bent - to do this, shine a flashlight into the slot.

Method 5: Disassembly of the phone (extreme case)

If there's no way to do that, there's a partial disassembly, and it's a risky method that's only suitable for advanced users.

• 🔧 Setting screwdrivers T3–T5 (Xiaomi screws).
• 🧲 Removal suction cup.
• 📱 Plastic mediator (so as not to scratch the body).

Procedure:

1. Turn off your phone and remove all memory cards.
2. Heat the back cover with a hair dryer (temperature) ~50°C) for softening the glue.
3. Put the lid on the suction cup and carefully remove it with the mediator.
4. Unscrew the screws holding the metal plate over the tray SIM.
5. Remove the tray with your hands or tweezers.

⚠️ Warning: Disassembly voids warranty and may result in: 🔋 Damage to battery plume (fire risk!). 📶 Loss of water protection (if you break the sealed gaskets). 🚫 Mi Account block (on some models, protection is triggered at opening).

If you have never disassembled smartphones, it is better to contact the service. The cost of extracting a tray in the workshop is from 300 to 800 rubles (depending on the model).

💡

Disassembly of the phone is only justified if the tray is jammed mechanically (for example, after a fall).

Method 6: Alternative tools from the household

If you don’t have a paper clip or needle on hand, check these items:

• 🖊️ Ballpoint pen rod (take out the paste and use a plastic tube).
• 🧶 Knitting hook (thin, up to 1 mm in diameter).
• 🔑 Key to a bicycle nipple (suitable for wide holes).
• 📎 Dental floss with wax (if the tray sticks out 1-2 mm, you can try to pick it up with a loop).

What can't be used:

• ❌ Scissors or knives - scratch the body.
• ❌ Screwdrivers are too thick, break the mechanism.
• ❌ Toothpicks - crumble and clog the hole.

For models with hybrid slot (SIM + microSD, like in the Redmi Note 10 Pro, avoid excessive pressure – there are two independent fixers that can be bent.

What to do if the tray is jammed or broken?

If after attempting to remove the trays:

• 🔄 Not fixed (falls out when inserted) SIM-maps - check the spring for bending.
• 🚫 Not inserted back - inspect the contacts for contamination.
• 🔊 Screaming when moving - sand or dust hit.

Decisions:

1. Blow the hole with compressed air (a canister to clean the keyboard).
2. Wash the contacts of the tray with alcohol (at least 70%).
3. If the spring is broken, replace the tray (the cost of the part is 100-300 rubles).

For models with IP68 (For example, Xiaomi 13 Pro after unsuccessful attempts to check the tightness:

1. Put your phone in water for 30 seconds (no more). SIM-map!).
2. If drops appear under the screen - the seal is damaged, replacement is required.

💡

If the tray falls out when you vibrate (e.g., when you ring), put a thin layer of insulating tape under it, which is a temporary solution before you change the mechanism.
