Certainly — here’s a longer, slower, and more detailed guide to opening an Apple AirTag and replacing the CR2032 battery, roughly twice as long as before. This version gives more context, extra care tips, and troubleshooting detail for anyone doing this the first time or finding the twist mechanism stubborn.
🔧 How to Open and Replace the Battery in an Apple AirTag (Expanded Step-by-Step)
Apple designed the AirTag to make battery replacement simple, but in practice the stainless-steel back can be quite tight, and many people find it tricky the first time. These instructions break the process down carefully, including grip tips, battery contact advice, and testing afterward.
🧰 Tools and Preparation
What you’ll need:
-
A new CR2032 3-volt coin cell battery (standard lithium type).
-
A clean, dry workspace with good lighting.
-
A soft cloth or towel to prevent scratches.
-
(Optional) Thin rubber gloves or a rubber jar opener for grip.
-
(Optional) A non-metallic pry tool or coin if the back cover is very tight.
Before you start:
-
Make sure your hands are clean and dry—skin oils or moisture can make it harder to grip the cover.
-
Wipe the AirTag with a dry microfiber cloth to remove dust or lotion residue.
-
Work on a table where a small round object won’t roll off; the cover and battery are small and easy to lose.
🌀 Step-by-Step Instructions
1. Position the AirTag
Place the white plastic side face-down on the soft cloth, so the shiny metal Apple logo side is facing up. The metal back is the part that comes off.
This position gives you a firm, stable base and prevents scratching the glossy white surface.
2. Press Down on the Metal Back
Using two thumbs (or your thumb and forefinger), press straight down on the metal cover. Apply steady, firm pressure. The spring tension beneath the cover is what holds it in place, and you’ll need that pressure to disengage it.
💡 Tip: You’re pressing against three small metal clips inside. The goal is to slightly compress those clips while turning the cover.
3. Rotate Counterclockwise
While keeping pressure down, turn the cover counterclockwise (to the left) about ¼ turn (roughly 30–40 degrees). You’ll usually feel a soft click when it unlocks.
If the cover won’t budge:
-
Try using a rubber glove, or press the back gently against a rubber surface for more friction.
-
If needed, insert the edge of a coin in one of the grooves around the perimeter and use it to help start the twist. Don’t use a knife or screwdriver—you could scratch or warp the metal.
4. Lift Off the Cover
Once unlocked, the metal back should lift off easily. Set it aside carefully—don’t drop it, as it can dent or deform.
You’ll now see the round CR2032 battery seated in its holder. Note its orientation before removing it: the positive (+) side is facing up, visible to you.
5. Remove the Old Battery
Using your fingers, gently lift the old battery out. If it’s snug, tilt it slightly from one side rather than prying straight up. Avoid using anything metallic to dig it out—metal tools can short the terminals.
Dispose of the old battery safely. Coin cells are recyclable and should never be thrown in household trash. Store it out of reach of children or pets until recycling.
6. Insert the New Battery
Take your new CR2032 3V cell. Hold it so the “+” symbol faces upward—that’s the side that should face you once installed. Place it into the slot and press gently until it’s flat and snug in its housing.
If inserted correctly, the AirTag will usually make a brief chirp—an audible confirmation that it has power again. If you don’t hear a sound, don’t worry; some units are quieter or may not beep immediately until sealed.
7. Check the Contacts (if No Chirp)
If the AirTag doesn’t chirp, check:
-
The metal contacts on the sides of the compartment—wipe gently with a dry tissue if dusty.
-
That the battery is truly seated flat (not tilted).
-
That you’re using a non-coated battery. Some brands (e.g., Duracell’s “child-safe bitter coating”) have a clear film that can block contact; if so, try another brand like Energizer, Panasonic, or Sony.
8. Re-Attach the Metal Cover
Look at the three small tabs on the underside of the stainless-steel cover. These tabs align with three corresponding slots in the AirTag’s plastic rim.
-
Line them up carefully.
-
Press down firmly so the cover sits flush.
-
While pressing, turn clockwise (to the right) about ¼ turn until it stops or clicks.
You’ll feel the cover lock into place when the tabs engage.
⚙️ Don’t over-tighten — once it stops, you’re done. Forcing it further could bend the tabs.
9. Test Your AirTag
Now, test that everything is working:
-
Bring it near your iPhone. The Find My app should detect it.
-
You can also play a sound from the app to confirm it’s functioning.
-
If the AirTag doesn’t respond, remove and re-insert the battery once more, ensuring solid contact.
⚠️ Safety and Care Notes
-
Keep batteries away from children and pets. Even one swallowed coin cell can cause severe internal burns within hours.
-
Don’t mix old and new batteries. Replace only with one fresh cell.
-
Avoid moisture. The AirTag is water-resistant but not waterproof. Re-seal promptly after opening.
-
Never use metal tools or pliers to twist open the cover—they can scratch or deform the thin steel rim.
-
Handle gently. The AirTag’s clips are small and spring-loaded; bending them could affect water resistance.
♻️ Battery Disposal and Recycling
-
Collect used coin cells in a non-metallic container and take them to a battery recycling point or electronic-waste facility.
-
Many electronics stores and supermarkets have collection bins.
-
If you must store used batteries temporarily, tape over the terminals with masking tape to prevent accidental short-circuiting.
🔄 Summary of Key Points
-
Use a CR2032 battery, positive side up.
-
Press firmly and twist counterclockwise to open, clockwise to close.
-
Align the three tabs carefully on reassembly.
-
Expect a chirp when the battery is making contact.
-
Keep the AirTag clean and dry, and recycle the old battery responsibly.
