The AirTag case opens by twisting, not pulling

Apple's AirTag comes in a white plastic case that holds the battery and the tracking chip. To open it, you twist the two halves apart rather than pry or pull them. Hold the larger bottom half steady in one hand, then grip the smaller top half and rotate it counterclockwise about a quarter turn. The case will separate cleanly without force.

The case is designed to come apart this way — it's not a sign of damage if it opens easily. Many people expect to pull straight up because that's how other small cases work, but the twist mechanism is what Apple chose to prevent accidental openings while you're carrying the AirTag in a pocket or bag.

Key Takeaways

  • Twist the top half counterclockwise while holding the bottom half still; do not pull or pry upward.
  • The case separates after about a quarter turn, and no force is needed if you're twisting in the right direction.
  • You'll see a small CR2032 battery inside once the case is open, along with a metal contact point on the top half.
  • The case reassembles by twisting the top half clockwise until it sits flush with the bottom half again.

What you'll see inside the case

Once the case is open, you'll find a small silver coin-shaped battery called a CR2032. This is a standard battery you can buy at any pharmacy, grocery store, or electronics retailer. The battery sits in a small circular compartment on the bottom half of the case.

On the inside of the top half, you'll see a metal contact point that touches the battery when the case is closed. This completes the electrical circuit that powers the AirTag. If the AirTag stops working, the battery is usually the reason — it lasts about one year under normal use.

Replacing the battery

If your AirTag has stopped making sound or stopped showing up in the Find My app, the battery is likely dead. You can replace it yourself by opening the case and lifting out the old CR2032 battery. Drop in a new CR2032 battery with the positive side facing up (the side marked with a plus sign), then twist the case closed again.

A new CR2032 battery costs between $3 and $8 depending on where you buy it and how many you purchase. You don't need any tools — your fingers are enough. After you insert the new battery, the AirTag will start working again within seconds.

Why the twist design matters

Apple chose a twist-open case instead of a snap or pull design to reduce the chance of the case opening by accident. If the case popped open easily, the battery could fall out while the AirTag is in your pocket, your bag, or attached to your keys. The quarter-turn twist requires intentional motion, so it's less likely to happen by chance.

This design also means the case stays sealed well enough that the AirTag can survive a wash if it ends up in a pocket. The case is water-resistant but not waterproof, so while it can handle brief contact with water, you shouldn't submerge it intentionally.

Common mistakes when opening the case

The most common mistake is pulling straight up on the top half instead of twisting it. If you pull, the case won't budge, and you might think it's stuck or broken. It's not — you're just pulling in the wrong direction. Stop pulling and try twisting instead.

Another mistake is twisting clockwise instead of counterclockwise. If you twist the wrong way, the case will tighten rather than loosen. If this happens, straightforward reverse direction and twist counterclockwise. There's no damage from twisting the wrong way — just twist back and try again.

Reassembling the case

Once you've replaced the battery or inspected the inside, put the case back together by aligning the two halves and twisting the top half clockwise. You'll feel a slight resistance as the threads engage, and the case will sit flush when it's fully closed. You don't need to twist hard — just turn it until it stops naturally.

If the case doesn't sit flush or feels loose after you've twisted it, open it again and check that the battery is sitting flat in its compartment. A battery that's tilted or standing on edge can prevent the case from closing properly. Once the battery is flat, the case should close smoothly.

Frequently Asked Questions

What if I twist too hard and the case cracks?

The plastic is fairly durable, and you shouldn't need to force the twist. If you're meeting resistance, you're probably twisting the wrong direction. Stop, reverse direction, and try again. Twisting too hard can crack the case, but this is rare — most people find the case opens with light pressure once they're twisting the right way.

Can I open the case without removing the battery?

Yes. You can open the case and look inside without taking the battery out. The battery will stay in place as long as you keep the case level or upside down. Just be careful not to tilt it sideways, or the battery might slide out.

Is the AirTag waterproof if the case is closed?

The case is water-resistant, not waterproof. It can handle splashes and brief contact with water, like if it gets rained on or ends up in a pocket during a wash. Don't intentionally submerge it, and if it does get wet, let it dry completely before opening the case.

Do I need to buy a replacement case if mine gets damaged?

Apple sells replacement cases separately, and third-party cases are also available. If your case cracks or the twist mechanism breaks, you can buy a new one and transfer the battery and AirTag to it. Replacement cases cost between $10 and $30 depending on the style.
