I have had the Kwikset lock in place for 5 months and it always seemed to have a hard time locking and unlocking. I took the lock apart and repositioned the deadbolt multiple times and never could get a clean locking and unlocking. As of now, 5 months after purchase, the motor makes the noise that its unlocking the door but doesn't do anything even with the lock out of the door and free of any friction. I wish I could just get this thing replaced.
