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.
