The Nokia Treasure tag is an amazing companion for your Nokia Lumia phone. It uses NFC (Near Field Communication) to help you keep track of your things like keys, bag/purse etc, by making an audible beep when the phone and the tag are beyond bluetooth reach of one another.
However, over time the Nokia Treasure Tag may stop responding to your phone and it may seem nothing works, including removing and re-installing the battery.
If this happens, here is a fix:
1. Open the battery compartment of your treasure tag using a tiny screwdriver or pointed object.
2. Remove the battery.
3. Press and hold the multifunction button your treasure tag while you re-install the battery. Press and hold it till you put the battery cover back in place.
Your tag is now reset and you can pair it once again with your Lumia phone.
