Troubleshooting
| Problem | Possible Cause | Solutions: |
| Deadbolt does not activate when the door closes. | The sensor in the lock body is too far from the magnet in the strike plate. | • Try adjusting the strike plate, lock body position, or shims. |
| Deadbolt activates when the door is closed, but does not lock the door | Deadbolt may not be properly going into the deadbolt hole in the door. | • Make sure the deadbolt is going into the hole and not hitting the strike plate. If not, you must reposition the strike plate. • If the deadbolt is going into the hole, it may be hitting the bottom of the hole (if it is in a wooden door). In this case, drill a deeper hole |
| How to reset unit. | • When testing, if necessary, reset the unit by grounding the orange wire momentarily. | |
| For any other problems. | • Replace the unit, and test again. A problem unit can also be substituted for a working unit in another door frame to see if it works there. |
