So, I realize this is a somewhat stale thread and possibly even unrelated to what I experienced.. however, as it was found when I was searching for solutions to my issue, I figured I’d post here in case it helps others.
I have a BE469 that is just regular ZWave (not Plus).. maybe that’s the BE469Z, I’m not sure. It recently started reporting to SmartThings that the state was “unknown”. It would often get “stuck” in a locked state or simply not lock at all. It would try it’s requested actions (lock/unlock) twice and then beep at the end and show a red X. I opened a ticket with Schlage and they had me do a factory reset, exclusion, inclusion, yada yada.. nothing helped. They gave up and told me to order a new lock. So, I decided to start pulling it apart to debug it.
It was mega easy to pull apart, so I’m not going in depth on that; but take a gander at the photos below.
Once this interior part is off the door after removing two screws and pulling off the keypad’s cable from the control board, then it’s really just three more little screws, disengage 4 (I think) pressure clips that hold the circuit board down. Keep an eye on the “interior” Schlage button and it’s frame (on the front side, not pictured) and pull it open like a book.
I found this rather import chunk of metal had fallen loose.
This is a close up of the gears the way I found them.
This is how it’s SUPPOSED to look (for a door latch on the left configuration). I stole this next picture from a review on the internet, where the user was swapping supported latch positions to the right side. [google search result linked, hoping it would help someone find it easily]
I straightened and super glued that little metal conductor piece where you see it in the borrowed picture above. I aligned the top plastic chunk in the same relative position as you see in the photo. That plastic piece spins somewhat freely along w/ the thumb knob on the other side.
I didn’t take a “finished photo” because I was SURE I’d be reopening this thing to tweak it again; but alas, I put it all back together (carefully) and it worked perfectly on my first try! I have no idea how LONG it will last. I noticed the latch is a little stiff with friction, so I’ll pull the latch mechanism apart later and give it a good lube job. That probably contributed to this problem.
While putting it back together, I struggled for a minute to get the circuit board to go back to where it came from in the frame. But the trick, for me, was to align the top side (where the battery module is into the metal frame first. Part of that section needs to be on both sides of the metal frame. In the first picture you can see a little slot where one side of the top of the “guts” rests, and the battery module goes on the other side. Yes, I left the batteries attached while doing this. It is not necessary to do that; but I was planning to keep an eye on the Zigbee status signal in the debug dashboard mentioned earlier in this thread or even in the SmartThings app. But, I forgot to look at that as I was putting it back together and just tossed it back on the door and tested it. It cycled a time or two to adjust it’s positioning and then wham.. it showed a real status of locked or unlocked!
Good luck. I hope this helps someone else! I have two more similar locks (but ZwavePlus).. I assume they’ll do the same thing one day, so when I search for the solution, I hope to find this post.
