You're staring at that little silver and white disc, and it's dead. Or maybe the low battery notification on your iPhone has been pestering you for three days straight. You try to twist it. Nothing. You try to pry it with a fingernail. Ouch. Honestly, for a company that prides itself on "intuitive" design, Apple made the process of how to open Apple AirTag surprisingly fiddly. It’s one of those things that feels like you’re going to break it right up until the second it actually pops open.
Don't panic. You won't break it. Well, probably not.
The AirTag uses a CR2032 lithium 3V coin battery. These things usually last about a year, though if you're constantly triggering the "Precision Finding" ultra-wideband chip because you lose your keys in the couch every twenty minutes, it might die sooner. When it does, you’re forced to confront the seamless, button-less exterior of the device.
The Press and Twist Method (The Only Way That Works)
The secret isn't strength. It's friction. If your hands are even slightly greasy from a slice of pizza or some hand lotion, you’re going to have a bad time. Wash your hands first. Seriously.
To get started, hold the AirTag with the polished stainless steel battery cover facing you. You want to press down firmly on that silver center piece with both thumbs. While maintaining that downward pressure, rotate the cover counterclockwise. It only needs to move about a fraction of an inch—maybe fifteen degrees. Once it hits the stop, you can just lift the cover off.

It sounds simple, right? It isn't always. Sometimes the seal gets stuck, or the internal tension is just higher than expected. If your thumbs are sliding, try using a rubber jar opener or even a piece of duct tape to get a better grip. Just don't use a screwdriver. Metal on metal is a recipe for deep, ugly scratches that you’ll see every time you look at your keychain.
What’s actually inside?
Once you’ve successfully figured out how to open Apple AirTag, you’ll see the battery sitting there. It’s just a standard CR2032. However, there is a massive catch that catches people off guard. Apple explicitly warns against using batteries with a bitterant coating.
You know that nasty, bitter taste they put on small batteries to stop kids from swallowing them? Duracell and several other major brands use it. That coating can react with the AirTag's contact points and prevent it from powering on. If you pop a brand new battery in and the AirTag stays silent, it’s almost certainly because of that coating. Use a plain, uncoated battery or wipe the "bitter" one down thoroughly with an alcohol swab before installing.
Why Does It Feel So Hard to Open?
Apple didn't do this just to annoy you. The AirTag has an IP67 rating. That means it’s water-resistant up to a depth of one meter for thirty minutes. To achieve that without a charging port, they had to create a very tight mechanical seal. The pressure-and-twist mechanism compresses a tiny internal gasket.
If the AirTag was easy to open, it wouldn't be waterproof.
Common Mistakes During the Process
Most people try to "unscrew" it like a jar lid. It's not a threaded screw. It’s a bayonet mount. If you aren't pushing down while you turn, the locking lugs won't clear the internal notches. You’ll just be spinning your wheels, or rather, spinning your thumbs.
Another weird issue? Putting the battery in upside down. The positive (+) side—the side with the writing—must face up toward you. When you drop it in, the AirTag should play a little chime. It’s a friendly "I'm alive" sound. If you don't hear that chirp, don't bother putting the cover back on yet. Something is wrong. Either the battery is dead, the bitterant coating is blocking the signal, or you’ve got it in backward.
Reassembling the Tag Without Losing Your Mind
Putting the cover back on is actually harder than taking it off for some people. Look closely at the silver cover. You’ll see three little metal tabs. Those have to align perfectly with the slots on the plastic housing.
- Drop the battery in (hear the chirp!).
- Align the three tabs on the cover with the slots.
- Press down firmly.
- Rotate clockwise until it stops.
If it feels "crunchy" or won't sit flush, stop. Don't force it. Take it out, realign, and try again. If it isn't seated perfectly, you lose that water resistance. One rainy day or a drop in a puddle, and your $29 tracker becomes a $29 paperweight.

Dealing with Stuck Covers and Damaged Units
Sometimes, especially if the AirTag has been attached to a dog collar or a gym bag, dirt and grime get into the tiny seam between the metal and the plastic. This acts like glue. If you absolutely cannot get it to budge with your thumbs, try this:
Find a piece of strong adhesive tape. Stick it across the silver cover, leaving two "tails" you can grab. Use those tails to help you apply rotational force while you push down with your palm. It gives you way more leverage than just skin-to-metal contact.
Also, check for physical deformation. If the AirTag has been stepped on or crushed, the stainless steel cover can slightly warp. If it's warped, the bayonet lugs won't line up. At that point, you might be looking at a replacement rather than a battery swap.
The Environmental Factor
One thing experts like those at iFixit point out is that the AirTag isn't really designed to be repaired beyond this battery swap. The internal logic board is glued into the plastic housing. If you manage to get the battery out but notice corrosion inside—maybe from a leak or salt water—you're basically done. You can try cleaning it with 90% isopropyl alcohol and a Q-tip, but don't hold your breath.
Actionable Steps for AirTag Maintenance
Maintenance isn't just about waiting for the battery to die. If you want your AirTag to last more than a couple of years, you should be proactive.
First, check the battery level in the Find My app occasionally. It won't give you a percentage, but it will show a low-battery icon when it's getting close to the end. Buy a pack of non-coated CR2032 batteries before you need them. Brands like Panasonic or Energizer (the non-bitterant versions) are generally the most reliable for this specific device.

Second, if you use your AirTag in a high-impact environment, consider a rugged case. The standard Apple keyrings are fine for office life, but if this thing is on a mountain bike or a pet, the constant vibration can actually loosen the battery cover over time. It’s rare, but it happens.
Finally, every time you open Apple AirTag to swap the battery, take ten seconds to wipe the internal gasket with a dry microfiber cloth. Removing skin oils and grit ensures that when you twist it back shut, the seal remains airtight.
Keep your thumbs dry, push harder than you think you need to, and listen for that chime. That’s all there is to it. Once you’ve done it once, the second time is a breeze.
