Mechanical Troubleshooting

Premise

In the event of a suspected mechanical failure, you could check that the internal mechanism is triggering as intended. 
This is only done when a lock is accepting a card (green light, single beep), but is not unlocking the door.

Note: This will require the removal of the lock from the door. The process typically only requires a screwdriver and no special knowledge.


Steps

1. Remove the lock from the door by unscrewing the 2 screws on the inside-part of the room. This will loosen the lock, and allow you to remove the front half from the door.



3. Ensure that the lock has batteries and tap a Master Card (or any valid card) to the lock.


4. Observe:

4a) Does the motor engage? You should be able to see the motor push a pin down into the spindle chamber.


- If the motor does not turn at all (no sound): there may be an issue with the motherboard. Replace the motor with one from another lock to confirm.
- If, with another motor, there is no sound: The issue is the motherboard. Otherwise, if a 2nd motor runs fine, the issue is the motor.
- If the motor runs, but does not push down: Ensure that the pin (near the bottom of the red circle) is moving freely and is not jammed
- If the pin is moving freely and the motor still does not engage: Pull down on the plunger of the motor and tap a card to the lock with the plunger held down to run a cycle or two.

4b) If no response comes from the lock at all - Check the battery connector. Is it rusty? Are any of the cables damaged?
