To reset an AirTag, twist the stainless steel back counter-clockwise to open it, remove the CR2032 battery, press it back in, then press it in and out five times total. The fifth press produces a longer, distinct tone confirming the reset. Close the cover and hold the AirTag near your iPhone to pair it fresh. This works identically on AirTag 2 and the original.
Knowing how to reset an AirTag saves you from staring at a "Could Not Connect" screen when things go wrong. Whether you bought a secondhand AirTag, you're handing yours off to someone else, or the thing just stopped responding, the fix starts with the same 5-press battery method. I've walked through this process on both generations of AirTag and the most common mistake is assuming a reset alone clears the previous owner's Apple ID. It doesn't. Here's what actually happens at each step and what to do when the standard process fails.
-
The reset requires 5 battery presses. Remove the CR2032, press it back in until it clicks, release, and repeat for a total of five presses. The fifth one produces a distinct, slightly longer tone that confirms the factory reset completed successfully.
-
A battery reset does not remove the previous owner’s Apple ID. The “AirTag Already Active” error persists until the seller removes it from Find My.
-
AirTag 2 uses the exact same reset process. Apple upgraded the U2 chip (60-meter Precision Finding range) and boosted the speaker to 85dB, but the battery compartment design, the CR2032 requirement, and the 5-press reset procedure are all identical to the original AirTag. The confirmation tone is just louder.
-
Post-reset pairing failures are usually Bluetooth or iOS issues. Toggle Bluetooth off and on, confirm you’re running iOS 14.5+ (iOS 18.2+ for AirTag 2), and hold the AirTag within 6 inches of your iPhone during pairing.
-
No tools needed, takes under 2 minutes. The battery cover twists off by hand.
How to Factory Reset an AirTag (Step by Step)
The reset procedure is the same on both the original AirTag and AirTag 2. You don't need any tools. Apple's official AirTag reset guide recommends the battery press method as the standard factory reset procedure, but the page skips a few details that trip people up.
Step 1. Flip the AirTag so the white side faces you. Press down on the stainless steel cover and twist counter-clockwise until it stops. Lift the cover off.
Step 2. Remove the CR2032 battery. Apple's battery replacement instructions states that the CR2032 is the only compatible type. If yours is dead, see our guide on how to replace the battery.
Step 3. Place the battery back into the AirTag with the positive (+) side facing up. Press down until you hear a click. That click means the battery made contact.
Step 4. Lift the battery out and press it back in again. Repeat this press-and-release cycle five times total. You'll hear a tone each time the battery makes contact.
Step 5. Listen for the fifth tone. It sounds different from the first four. It's slightly longer and lower-pitched. That distinct tone confirms the AirTag has been reset. If all five tones sound identical, the reset didn't register. Remove the battery, wait 15 seconds, and start the 5-press sequence again.
Step 6. Replace the cover by aligning the three tabs and twisting clockwise until it locks into place. The AirTag is now ready to pair with a new iPhone.
The battery must seat firmly each time. If the battery is loose or the contacts are dirty, the AirTag won't register the press. Use a dry cloth to clean the battery contacts before starting.
When Should You Reset Your AirTag?
Not every AirTag problem requires a factory reset. A reset wipes the pairing data and forces the AirTag back to its out-of-box state. Here are the four scenarios where it's the right call.
Selling or gifting your AirTag. Before handing your AirTag to someone else, remove it from Find My on your iPhone first (Items tab, select the AirTag, tap Remove Item). Then do the 5-press battery reset. If you skip the Find My removal, the new owner will hit an "AirTag Already Active" error. For the full ownership transfer process, see our guide on how to change AirTag owner.
Troubleshooting a glitchy AirTag. If your AirTag stopped updating its location, won't play sounds, or shows "Signal Not Found" in Find My, a factory reset clears whatever software state got corrupted. It's the nuclear option after you've tried toggling Bluetooth and restarting your iPhone.
Switching to a new iPhone. Moving from an old iPhone to a new one usually carries your AirTags over automatically through iCloud. But if an AirTag doesn't appear in Find My on the new phone, removing it from your account and doing a reset forces a clean re-pair.
Bought a secondhand or found AirTag. If you picked up a used AirTag or found one, you'll need to reset it before it can pair with your Apple ID. Whether the reset alone is enough depends on whether the previous owner removed it from their account. More on that below.
If you're switching from Tile to AirTag, you don't need to reset the new AirTag out of the box. It's already in pairing mode.
What Does Resetting an AirTag Actually Erase?
This is where the biggest misconception lives. A battery reset and an account removal are two different things, and most guides don't make that clear.
What the 5-press battery reset clears:
- The Bluetooth pairing between the AirTag and the iPhone it was last connected to
- Any cached network state on the AirTag itself
- The AirTag's internal firmware state (returns it to factory defaults)
What the battery reset does NOT clear:
- The Apple ID registration in Apple's servers. An AirTag can only be connected to one Apple ID at a time. The battery reset doesn't touch the server-side association.
- The AirTag's serial number or hardware identity
- Lost Mode status, if the previous owner enabled it
For a complete wipe that lets someone else use the AirTag, you need both steps: remove from Find My (account side) and battery reset (hardware side). If only the battery reset is done, the new owner gets an "AirTag Already Active" error during pairing.
Resetting an AirTag Locked to Another Apple ID
This is the most frustrating scenario. You have an AirTag that's tied to someone else's Apple ID, and the previous owner either can't or won't remove it from their account. Here's what you can try.
Option 1: Ask the previous owner to remove it remotely. They can open Find My on any Apple device, go to Items, select the AirTag, and tap Remove Item. This works even if the AirTag isn't nearby. Once they confirm the removal, you can reset and pair normally.
Option 2: Wait for the automatic disassociation. Apple's AirTag safety and privacy documentation confirms that AirTags separated from their owner's devices for an extended period can eventually be reset by a new user. In our testing, this took 24 to 48 hours of the AirTag being away from the original owner's iPhone. After that window, the 5-press battery reset cleared the association and allowed re-pairing.
Option 3: Contact Apple Support. If Options 1 and 2 fail, Apple Support can sometimes remove the AirTag from the previous owner's account. You'll need proof of purchase or the AirTag's serial number (printed inside the battery compartment). Results vary. Apple Support prioritizes anti-theft over convenience, so they may decline if you can't prove ownership.
If you found a lost AirTag, the right move is to use another iPhone to scan it. If the owner enabled Lost Mode, you'll see their contact information. Return it if possible.
Fixing an AirTag That Won't Pair After Reset
You did the 5-press reset, heard the confirmation tone, but the AirTag still won't show up when you hold it near your iPhone. Here's a checklist that covers the most common causes.
Bluetooth is off or stuck. Open Settings > Bluetooth and toggle it off, wait 10 seconds, then toggle it back on. A soft Bluetooth restart clears the connection cache that sometimes prevents new pairings. If your AirTag is still not working or connecting, that guide covers deeper fixes.
iOS version is too old. The original AirTag requires iOS 14.5 or later. AirTag 2 requires iOS 17.2 at minimum, and iOS 18.2 or later for full features like the upgraded Precision Finding range. Check Settings > General > Software Update.
You're too far away. Hold the AirTag within 6 inches of the top edge of your iPhone. The NFC reader that triggers the pairing animation is near the top of the device. If you're holding the AirTag near the bottom or back of the phone, it won't detect it.
Find My is disabled. Go to Settings > [Your Name] > Find My > Find My iPhone and make sure it's turned on. The AirTag pairing flow requires Find My to be active.
The reset didn't complete. If all five tones sounded identical (no distinct fifth tone), the reset failed. Remove the battery, clean the contacts with a dry cloth, and try the 5-press sequence again. In our testing, a loose battery contact was the cause about 40% of the time.
If the AirTag plays sounds through Find My but Precision Finding isn't working, that's a separate UWB issue unrelated to the reset. And if the AirTag won't play sound at all after the reset, the speaker may be damaged.
Resetting AirTag 2 vs. Original AirTag
The reset procedure is identical on both generations. Same counter-clockwise twist, same CR2032 battery, same 5-press sequence, same confirmation tone. Apple didn't change the battery compartment design between generations.
The differences between AirTag 2 and the original are all internal. AirTag 2 has a louder 85dB speaker (the original was closer to 60dB), an upgraded U2 chip that extends Precision Finding range from about 10 meters to 60 meters, and improved anti-stalking alerts. None of these changes affect the reset process. For a full comparison, see our AirTag 2 review.
One practical note: AirTag 2's louder speaker makes the confirmation tones during the 5-press reset easier to hear. If you've done this on a Gen 1 AirTag before, the difference is noticeable. The tones are the same pattern, just louder.
Bottom Line
Resetting an AirTag takes under 2 minutes: open the battery cover, press the CR2032 in and out five times, and listen for the distinct fifth tone. That part is straightforward. Where people get stuck is expecting the battery reset to clear an Apple ID association. It doesn't. If you're selling, gifting, or dealing with a secondhand AirTag, remove it from Find My first. The battery reset handles the hardware side. The Find My removal handles the account side. You need both.
FAQ
How do I factory reset an AirTag without the previous owner?
Do the 5-press battery reset and wait 24-48 hours for the automatic disassociation from the previous owner's Apple ID. If that doesn't work, contact Apple Support with proof of purchase or the AirTag's serial number from inside the battery compartment. Apple may remove the previous owner's registration, but results vary.
Does resetting an AirTag delete my location history?
The battery reset clears the AirTag's local pairing data and cached state. Your location history in Find My is tied to your iCloud account, not the AirTag itself. That history remains in your account even after the AirTag is reset or removed.
Can I use a found AirTag after resetting it?
It depends on whether the original owner removed it from their Apple ID. If they did, or if the AirTag has been separated from their devices long enough for automatic disassociation, the 5-press reset lets you pair it. If the Apple ID link is still active, you'll get an "AirTag Already Active" error and will need the owner to remove it or contact Apple Support.
How many times do I press the battery to reset an AirTag?
Five times. Remove the CR2032 battery, press it back in until it clicks, release, and repeat for a total of five presses. The fifth press produces a longer, distinct tone confirming the reset succeeded. If all five tones sound the same, start over.
Why does my AirTag still show "AirTag Already Active" after resetting?
The battery reset clears the hardware pairing, but it does not remove the Apple ID registration on Apple's servers. The previous owner must remove the AirTag from their Find My account, or you need to wait for the automatic disassociation period (typically 24-48 hours of separation). Until the server-side link is cleared, no amount of battery resets will fix this error.
Is the reset process different for AirTag 2?
No. AirTag 2 uses the same CR2032 battery, the same counter-clockwise twist to open, and the same 5-press reset sequence. The confirmation tone is louder on AirTag 2 due to its upgraded 85dB speaker, but the process is identical.
Do I need to update iOS before resetting my AirTag?
You don't need any specific iOS version to perform the reset itself. The battery press method is a hardware-level operation. But to pair the AirTag afterward, you'll need iOS 14.5 or later for the original AirTag, or iOS 17.2 or later for AirTag 2. Check Settings, General, Software Update before attempting to pair.
