The ONE-KEY™ module stops broadcasting to the tracking network when the embedded coin cell battery dies. No error or alert is shown — tracking simply goes dark.

4) Carefully remove the module, swap the CR2032 battery, and reinsert.

5) Reconnect the tool in the ONE-KEY™ app to confirm tracking has resumed.
