If you have issues adding your card to Apple Find My or the AirBolt App, it may need a reset .
To rest your card, simply
1. Ensure it is charged - see instructions for charging your card here
2. Press the Shield button 3 (THREE) times BUT on the 3rd time press and hold the button for 20 seconds (it will play a melody)
3. You are now good to go as the card is reset.
