I purchased this deadbolt approximately 2 years ago. Installation was straightforward and the deadbolt functioned well until this week, when the deadbolt would not engage and move when using the electronic lock button or and entry code. The device will make a low grinding sound, but nothing moves. Key use works, though not as well as before as the lock sometimes hits a sticking point before extra torque will turn it in or out by key.

I have reviewed all Kwikset info for troubleshooting, as well as other sources. After troubleshooting with a battery change, rehanding, checking the clutch, all alignment, mounting tension, and a complete reset and reinstall, still no fix. On further inspection, it appears that the internal gear that moves the bolt when using the electronic mechanism have seized or stopped connecting or are somehow not engaging at the teeth (they are plastic). Overall very disappointed with this deadbolt that has received light use for two years.
