If your Mortise is not locking, it may be due to the following:
- Sensor/Timer Re-lock is disabled
- The door sensor on the Mortise and door frame magnet are misaligned
- Low battery or wrong batteries used
If you have disabled all Re-lock Modes, you can lock the door with '#' key on the Mortise from outside the door, and Open/Close or Thumbturn from inside the door.
