You can factory reset the NDE by doing the following:

  1. Press and hold the FDR button for five seconds.The NDE will blink green two times and beep two times.
  2. Turn the inside lever three times within 20 seconds.LED will blink red and lock will beep with each turn
  3. Reinstall battery cover, then use the app to capture your lock.Turn the inside lever. The NDE will communicate on BLE looking for your mobile device for two minutes after each lever turn in FDR mode.If you have used this NDE in Construction Access Mode, you must complete a FDR before it will communicate on BLE.
