If the padlock is using the connected latch option, please go here; otherwise, follow these instructions:
- Remove any tension on the shackle as this could prevent the detection of the open/close status of the padlock. Manually push the shackle down to verify if the LED changes from red to green. If the AP3 LED changes to green only while pressing the shackle down, then you could have a loose sensor, and the padlock would need to be replaced.
- Manually push the shackle down to verify if the LED changes from red to green. If the AP3 LED changes to green only while pressing the shackle down, then the AP3 has a damaged sensor, and the padlock would need to be replaced.
- Reset the internal mechanism of the padlock by following the instructions here.
- The user will then need to push the shackle down and verify if the LED is green.
- If the padlock is still shown as open when it's closed, connect an external charger to the micro USB port and repeat step #2. Please see the external power guide here.
- Report the padlock to the administrator if the padlock is still shown as open, as it is likely experiencing a hardware failure.
