The summary is, your situation is not unusual. My Kwikset 912 ran fine for over a year and then started to go downhill after that. I even replaced the Z-Wave module. A bit better for a while and then downhill again. I’ve now replaced it with a Schlage FE599. It’s only been since last Friday, but after going offline every 1 - 1.5 hours for the last month, this new lock has been perfectly happy to stay on line since Friday.
Some of those in the other thread are doing just that. I didn’t because my Z-Wave mesh is much stronger and Zigbee can have conflicts with Wi-Fi, so I chose to stay with Z-Wave but with a different lock and lock company.
I spend last night on the phone with kwikset they are saying it my locks, the yellow light beside the button “A” behind the paper, not the flashing indicator below, wants to stay on sometime, they said bad motherboard. but on both ? really and not the always.
but than also saying might be need signal extender, the lock is 10 ft other is 28, ok maybe the 28 but not the 10 with direct line of site.
I took them both off and sat them beside the adt smartthing hub, I going to leave them for a couple days see if they lose connection only being that close
also maybe way a lot coming in is because IRIS is being disconnect and everyone is switching .
I had that same yellow light next to the ‘A’ button on mine too. Kwikset says it’s a bad motherboard? That makes sense to me since changing my Z-Wave module didn’t seem to make the situation any better for me eventually. Yellow light kept coming on and the lock kept dropping from the mesh. Glad I gave up on it.
Any mains-powered Z-Wave device (i.e., not battery-powered) will act as a repeater/extender. However, keep in mind that Z-Wave locks are ‘beaming’ devices and to be effective for the lock, the Z-Wave extender you choose, also needs to be a ‘beaming’ device. (See here for more details)
HOWEVER, if the yellow light next to the ‘A’ button on your Kwikset indicates that the motherboard is bad - as was reported by Kwikset, adding Z-Wave extenders will not likely be of much use.
Also, replacing your lock with a WiFi lock might not be the best choice either. YMMV, but generally, WiFi devices have terrible battery life because they’re always on rather than Z-Wave or Zigbee’s more ‘sleepy’ protocols. Besides, the issue with the Kwikset locks isn’t that it’s Z-Wave. To be blunt, it’s because it’s a Kwikset with poor design and/or implementation of their motherboards or modules, or both.
So far (only since last Friday), it’s been perfect. Hasn’t dropped once. Works exactly as I expect it to. I’ll let you know in about a month too.
Note: Remember that you’re currently using a Kwikset 910 (deadbolt). I was using a Kwikset 912 (lever lock). The Z-Wave and electronic components seem very similar but the physical functionality of the locks are quite different. You’d likely be looking for something like the Schlage Z-Wave Connect Camelot Touchscreen Deadbolt with Built-In Alarm, Aged Bronze, BE469 CAM 716, or similar to replace yours. Not making a choice for you, just pointing out that my experience with the Schlage FWE599 Lever Lock isn’t necessarily an indication of how you’d do with a Schlage (or Yale) deadbolt .

I would advise against the 888/910/912 locks. Apart of the obvious issues discussed here (z-module, battery and motherboard issues) it also has two other problems that we’ve found in our testing:
It appears to have a bug where it reports a confirmed code programming to the hub but it actually fails and ends up deleting the code. This has been observed under heavy programming within a short period of time while, so I would not recommend this for use in places where you’re constantly changing a lot of codes, especially when the mesh is weak (which seems to exacerbate the issue)
It won’t accept all combinations of codes. E.g. 1234 and 2134, while they’re different the lock will reject the second one because it uses the same order or key presses and the lock can’t differentiate.
The following FAQ will help explain about locks and repeaters. It applies to all brands of zwave locks. (The thread title is a clickable link)
That said, that the problem was with your lock sounds like a device issue, not a network issue.
Kwikset is a budget brand. On a scale of good/better/best they are probably right in the middle of “good” where Schlage and Yale are at the high end of “better.” That doesn’t mean switching brands will fix all your problems overnight, there could still be network issues or cloud issues, but it does mean that other brands make better locks. But then they cost more, too. So it’s a personal decision.
Kwikset is one of the only brands with that feature. They actually get dinged for it on some lock ratings as it creates a small security vulnerability. So most of the better locks require individual pin rekeying rather than the pop-out method that Kwikset offers.
