AirTag's stainless-steel cover opens with a press-and-turn motion. This simple repair involves a serious coin-cell ingestion hazard. Apple’s guidance updated October 14, 2026 warns that swallowed batteries can cause severe internal burns. Prepare a child-safe work area and secure old batteries immediately.

1. In Find My on your iPhone, choose Items and your AirTag, then check for a Low Battery indication.
2. Work away from children and pets. Prepare a compatible CR2032 lithium 3V battery and a secure place to contain the used cell.
3. Press down on the polished metal cover and turn it counterclockwise until it stops. Remove the cover and old battery without leaving either unattended.
4. Insert the compatible new CR2032 with its positive (+) side up. A chime indicates contact. Some bitterant-coated cells may be incompatible; check the package for AirTag compatibility.
5. Align the cover's three tabs with the AirTag's three slots and turn clockwise until it stops. Do not use it if the cover is loose.
6. Immediately secure both used and spare coin cells out of children's reach and dispose of them according to local rules. If swallowing or insertion into the body is suspected, seek emergency medical care immediately, without waiting for symptoms.
