Apple AirTags are small, powerful tracking devices designed to help you find everyday items like keys, wallets, bags, and even bikes. Powered by Apple’s Find My network, AirTags leverage millions of Apple devices worldwide to locate lost items securely and privately.
This complete guide covers what AirTags are, how to set them up, how they work, and how to troubleshoot common issues.
What Is an Apple AirTag?
An AirTag is a coin‑sized Bluetooth tracker that connects to your Apple ID and appears in the Find My app. When an AirTag is near any Apple device, its location can be anonymously relayed to you—even if the AirTag itself doesn’t have an internet connection.
Key Features
- Precision Finding (on iPhone models with U1 chip)
- Replaceable CR2032 battery
- Water and dust resistance (IP67)
- Ultra‑Wideband (UWB), Bluetooth, and NFC support
- Privacy‑focused tracking
What You Need Before Setup
Before setting up an AirTag, make sure you have:
- An iPhone or iPad running the latest iOS or iPadOS
- Apple ID signed in
- Bluetooth enabled
- Find My turned on
- Two‑factor authentication enabled
AirTags cannot be set up using Android devices.
How to Set Up an Apple AirTag
Step‑by‑Step Setup
- Unbox the AirTag
Remove the plastic tab to activate the battery. - Bring AirTag Near Your iPhone
Your iPhone will automatically detect it and display a setup prompt. - Tap “Connect”
Choose an item name (Keys, Backpack, Wallet) or create a custom name. - Link to Your Apple ID
The AirTag will be registered to your Apple ID and appear in the Find My app. - Finish Setup

How Apple AirTags Work
AirTags use a combination of:
- Bluetooth to communicate with nearby Apple devices
- Ultra‑Wideband (UWB) for precise direction and distance tracking
- Find My Network, which anonymously relays location data
- End‑to‑end encryption to protect your privacy
Apple cannot see the AirTag’s location—only you can.
Using Precision Finding
If you have an iPhone with a U1 chip (iPhone 11 or newer, excluding SE models):
- Open Find My
- Tap Items
- Select your AirTag
- Tap Find
Your phone will guide you with arrows, distance indicators, and sound cues.
Sharing an AirTag (Supported Models)
You can share an AirTag with trusted contacts:
- Open Find My → Items
- Select the AirTag
- Tap Add Person
- Choose a contact and send an invite
Shared users can see the location but cannot manage or remove the AirTag.
Battery Replacement Guide
AirTags use a standard CR2032 coin battery.
How to Replace the Battery
- Press down on the stainless steel back
- Twist counterclockwise
- Replace the battery (positive side up)
- Twist back until it clicks
Battery life typically lasts about one year.
Tip: Some CR2032 batteries with bitter coatings may not work reliably.

AirTag Making Unexpected Sounds
This is a privacy feature to prevent unwanted tracking.

- Reinsert it until you hear a sound
- Repeat this process five times
- On the fifth time, leave the battery in and re‑pair the AirTag
Privacy and Safety Features
Apple includes multiple safeguards:
- Randomized Bluetooth identifiers

- Sound alerts from AirTags separated from owners
AirTag Limitations You Should Know
