How to replace the battery in the AirID tag#

Updated October 19, 2026

The AirID tag runs on a CR2032 battery. It lasts about 6 months, depending on how often you use the car. When the battery is low, the app sends a Tag discharged notification.

How to open the tag#

Carefully separate the housing by prying it through the slot at the bottom. Do it over a table: the board and the battery aren't fixed and can fall out.

How to reassemble the tag with a new battery#

  1. Place the front part of the housing logo side down on a flat surface.
  2. Put the board in place components side up and press until the latches click.
  3. Place a new CR2032 battery positive side up.
  4. Cover with the back part of the housing and gently press until it fully closes.

If the tag runs out on the road, authorize with your PIN code. If you don't remember it, see How to authorize without a tag or PIN code.
