I have a Kwikset 910 lock that I had on my front door and was paired with my ST before I got HE. When I got my HE, I bought a Schlage lock and replaced the Kwikset lock on the front door and placed the Kwikset lock on my side door.
It has worked flawlessly for a month and half at least. I can lock/unlock it from the device details page, Dashboard, and I have a few rules that use it. Everything worked reliably until last night.
I noticed last night that my Kwikset lock did not lock when the front door lock was locked. So after a bit of investigating, I noticed it would not respond to any commands from anything. Well I say it wouldn't, I should clarify. If I locked it via the Dashboard it would do nothing, and then a few minutes later it would lock. I figured I would look at it more today.
Today I replaced the batteries, and it still would not work reliably. I excluded it from HE. Paired it again sitting 6 inches from HE and it paired securely in a few seconds. Moved it back to its normal location. Nada, I have repaired the ZWave network twice to no avail.
I have a Z Wave Plus switch not six feet from it.
Do the Z Wave radios just crap out on them? That is the only thing I can figure has happened. Nothing new has been added to my system except a Hampton Bay fan controller. I can't for the life of me figure this out.
I threw my Kwikset 910 in the trash, to be honest. That unit, which I had for about 1.5 years, gave me nothing but headaches no matter what platform I had it connected to. I had at least a dozen calls with Kwikset about it and finally just tore it off the door and replaced it with a Yale YRD226 (Zigbee model) and have never been happier.
I believe that you can contact Kwikset about a replacement Z-Wave module though.
I have not had many of the problems that others have experienced with it. It has performed rock solid for me with ST first and then HE.
I was going to find a Zigbee module for it before I gave up on it. I have had no luck with that. I didn't think about calling Kwikset. Maybe I can talk them into sending me a Zigbee module
I've got a repeater/beaming plug device that will be here anytime. Will place it about 4 feet from the lock and see if it starts back up.
It has worked flawlessly for a month and half at its present location without any issues. If this doesn't work, I am going to go with the ZWave radio has failed. I may try to find a Zigbee radio to put in it or get a Yale or another Schlage lock to replace it.
I believe that's a more robust unit with an upgrade slot, where you can change the module.
Pretty sure the 910 lacks that and it's soldered right onto the board.
I don't have access to any type of module on my 910.
EDIT: I see he says it should work with 910, but I don't know how...
I have 5 Kwikset locks - 4 910's and one 914. Within the last two days, all five have quit responding to HE. They neither update their status nor does HE operate them. I did a Z-wave repair to no avail. I did a factory reset on one (press B button 9 times) then re-discovered it. Still no love.
I noticed when I send a command to the lock, the red LED behind button A lights up momentarily, so HE is apparently communicating with the lock, but nothing happens. Replaced the batteries, no help.
I can't believe all 5 locks would break at the same time.
After trying a reboot with no success, I completely shut HE down, unplugged it, then plugged it back in. Now the locks are all working fine. I guess a reboot doesn't restart the Z-wave dongle.
