Recommended Action:
-
1Inspect the mounting plate and screws for damage or wear. Replace damaged screws with new ones of the same size and thread type.
-
2Tighten the mounting screws using a manual screwdriver, not a power drill, to avoid over-tightening. Apply a small amount of thread locker (e.g., Loctite 242) to the screw threads.
-
3If the door is hollow, consider adding reinforcement to the mounting area. Options include installing a solid wood backing plate or using longer screws that penetrate deeper into the door frame.
-
4Check the deadbolt alignment. Ensure the deadbolt extends and retracts smoothly without binding. Adjust the strike plate if necessary.
-
5Lubricate the deadbolt mechanism with a silicone-based lubricant to reduce friction and strain on the motor.
-
6If vibration persists, contact August support for warranty assistance or possible motor replacement.
-
7Monitor battery health closely, especially during winter. Replace batteries proactively to avoid lock failure in cold temperatures.
