How to Fix AirTag Beeping or Chirping Randomly

Device: Apple AirTag · Apple Added

Causes

  • Anti-stalking safety feature — Apple designed the AirTag to emit a chirping sound (approximately 2 seconds, two-tone ascending chime) when it detects that it has been separated from its paired iPhone for an extended period. Per Apple's anti-stalking protocol, an AirTag will play this sound after 8-24 hours of being away from its owner's device to alert nearby people that a tracking device is present. This is the single most common reason for unexpected AirTag beeping, and it is intentional behaviour — not a malfunction
  • Separation from the paired iPhone beyond Bluetooth range — the AirTag uses Bluetooth Low Energy (BLE) to communicate with its paired iPhone. When the AirTag is out of BLE range (approximately 10-30 metres depending on obstacles) for an extended duration, it cannot verify its owner's presence. After a cumulative separation of 8 hours (not necessarily continuous), the anti-stalking timer triggers the chirp. This happens frequently when you place an AirTag in checked luggage during air travel — the luggage is out of BLE range for the entire flight duration, accumulating separation time quickly
  • AirTag travelling with someone else who is not its owner — if an AirTag is in a shared item (a family car, a communal set of keys, a shared backpack) and the paired iPhone stays at home or in a different location while the AirTag moves with another person, the AirTag detects that it is not travelling with its owner and begins chirping after the 8-hour threshold. This is the anti-stalking system working as designed to protect the person unknowingly carrying the AirTag
  • Low battery warning chime — when the CR2032 battery voltage drops below approximately 2.7V, the AirTag emits a different, slightly lower-pitched chirp (a single tone, not the two-tone anti-stalking chime). This is a low-battery alert that occurs once after the battery crosses the threshold, then again every 24 hours until the battery is replaced. Users often mistake this for the anti-stalking chirp
  • Software bug in the Find My network logic — some versions of iOS (specifically iOS 17.3 through 17.5 and early iOS 18.0 builds) shipped with a bug in the Find My firmware update mechanism that caused AirTags to lose sync with their paired iPhone's presence timer. Affected AirTags would chirp erratically every 2-4 hours even when the paired iPhone was within BLE range. Apple addressed this with AirTag firmware update 2A36 (released May 2024) and iOS 18.1, but some AirTags not running the latest firmware may still exhibit this behaviour
  • AirTag firmware corruption after failed OTA update — AirTag firmware updates are delivered wirelessly via the paired iPhone when the AirTag is within BLE range and charging (the AirTag is considered "charging" when the battery is above 80%). If the iPhone loses Bluetooth connection during a firmware update — for example, if you walk out of range mid-update — the AirTag's firmware can become partially corrupted, causing the anti-stalking timer logic to malfunction and trigger chirping at random intervals

How to Fix

  1. Identify which type of chirping you are hearing — place the AirTag next to your ear or in a quiet room and listen carefully. The anti-stalking chirp is a distinct two-tone ascending chime that plays once and repeats every 1-2 minutes if the trigger condition persists. The low-battery chirp is a single lower-pitched tone that plays once and then repeats every 24 hours. If the chirp is the single low-battery tone, replace the CR2032 battery (refer to the "Battery Not Working After Replacement" fix guide). If the chirp is the two-tone anti-stalking chime, proceed with the steps below
  2. Bring the AirTag close to its paired iPhone — hold the AirTag within 1 metre of its paired iPhone for at least 10 seconds with Bluetooth enabled on the phone. This allows the AirTag to re-establish a secure BLE connection and reset its anti-stalking separation timer. Open the Find My app, go to the Items tab, and tap on your AirTag. You should see "Connected" in green text beneath the AirTag name once the connection is established. The chirping should stop within 1-2 minutes of reconnection. If the chirping continues for more than 5 minutes after reconnection, proceed to step 3
  3. Disable and re-enable the "Notify When Left Behind" feature — open the Find My app on your paired iPhone, tap the Items tab, tap on your AirTag, scroll down to "Notifications," and tap "Notify When Left Behind." Toggle the switch OFF, wait 10 seconds, then toggle it back ON. This resets the separation detection state machine that controls the anti-stalking timer. The AirTag should receive the updated state within 30 seconds and stop chirping. If the chirping persists, force-quit Find My (swipe up from the bottom of the screen on iPhone X and later, or double-click the Home button on iPhone SE/8 and earlier) and re-open it
  4. Update your AirTag firmware via the paired iPhone — ensure both your iPhone and AirTag are running the latest firmware versions. On your iPhone, go to Settings → Bluetooth → tap the "i" icon next to "AirTag" under My Devices — this shows the current AirTag firmware version. The latest version as of mid-2026 is 2A60 (iOS 19 series) or 2A52 (iOS 18 series). To trigger a firmware update: place your AirTag within 1 metre of your iPhone, ensure Bluetooth is on, connect your iPhone to Wi-Fi, and plug your iPhone into a charger. Leave them undisturbed for at least 30 minutes. The firmware update happens automatically in the background — you do not need to tap anything. Check the firmware version again after 30 minutes. An updated firmware resolves software-caused chirping bugs
  5. Reset your AirTag by removing and reinserting the battery — press down on the polished stainless steel back cover and rotate counter-clockwise to unlock. Remove the cover and take out the CR2032 battery. Wait 60 seconds — this ensures all capacitors in the AirTag's circuitry fully discharge, clearing volatile memory including the anti-stalking timer state, connection logs, and any partially corrupted firmware flags. Reinsert the battery with the positive (+) side facing up, replace the cover and rotate clockwise to lock. You should hear the startup chime. Re-pair the AirTag with your iPhone by holding it near the top edge of the phone and following the on-screen Connect prompt. This full power cycle clears transient firmware bugs without losing your paired settings
  6. Perform a factory reset via the Find My app — open Find My → Items → tap your AirTag → scroll to the bottom and tap "Remove Item" → confirm with "Remove." This unpairs the AirTag from your Apple ID completely. Wait 60 seconds, then press the AirTag against the top edge of your iPhone and tap "Connect" to re-pair it as a new device. A factory reset clears all accumulated state including any corrupted anti-stalking timer thresholds that standard battery removal may not reset. After re-pairing, test for 24 hours — if the chirping returns only after being genuinely separated from your iPhone for 8+ hours, it is the anti-stalking feature working correctly and not a malfunction
  7. Use the "Play Sound" feature to verify the AirTag's speaker is functioning normally — in Find My → Items → tap your AirTag → tap "Play Sound." The AirTag should play a rising chirp sequence that is louder and longer than the anti-stalking chirp. If the speaker sounds distorted, muffled, or silent, the AirTag speaker may have water damage or a manufacturing defect. The AirTag has an IP67 water resistance rating (1 metre for 30 minutes), but the speaker membrane can be damaged by pressure changes (airline cargo holds) or immersion beyond its rating. Contact Apple Support for a replacement if the speaker is defective
  8. If the AirTag is in shared luggage or a communal item, add a family member as an additional owner — AirTag does not natively support sharing tracking with another person in the same way as AirPods or Apple Watch. However, you can use Family Sharing to allow authorised family members to receive separation alerts. In Find My → Items → tap your AirTag → "Share This AirTag" → add the family member's Apple ID. This prevents the anti-stalking chirp from triggering when the AirTag is with that family member instead of you. For non-family scenarios (e.g., a shared work vehicle), the chirp cannot be disabled by software — you must either keep the paired iPhone with the AirTag at all times, or accept the chirp as a safety feature. The anti-stalking chirp cannot be permanently disabled by the user; this is a deliberate privacy protection specified in Apple's regulatory commitments to the US Federal Trade Commission and EU consumer protection agencies
