I know, that’s why I wrote that the way I did 
The issue is battery life
of days vs weeks or months. My main point was that in my case the issue
seems to have been the loose connector, and maybe it is for others too.

Did this ever get resolved? I have a 910 with the same issue. I purchased “expensive” lithium batteries so I wouldn’t have to change them, but they lasted only a couple of weeks.
Ever since adding a SmartThings outlet near mine the batteries have been fine.

We have the Qwikset 916 and having the same issue - our router is on the second level of the house and door lock is on first. We added the Smartthings outlet close to the door lock but still having no luck.
You sure it’s a Z-Wave outlet? ST also has ZigBee devices.
Yes - it is z-wave plug-in smart switch by honeywell
Are you sure your KwikSet 916 is Z-Wave and not ZigBee? I have two KwikSet 910s, one has a ZWave card and one is ZigBee. The cards are interchangeable.
I will check but it Won’t be for a couple of weeks - it’s our vacation home and we came home this morning.
You can check online in the IDE under my devices. See what device handler it’s using.
Sorry for the delay - it is a zwave
Sorry - it is zwave and zigbee system.
Hi all, just had this problem with my 916. Dead batteries at midnight, swapped out (tested them first), then had dead batteries less than 24 hours later. Called Kwickset and they walked me through resetting my system by pressing the circle button for 30 seconds then when it went to a red light take my finger off press the button again take my finger off. It kills all the codes I was told, so had to add a code to test it back.
Basically what that did was discharged the capacitor which can have juice in it showing the system the battery is dead. However when I checked the batteries that I just placed the night before all of them had a charge to him just like what it was previously.
So now I’m testing to see if the new batteries I just placed in tonight are going to last more than the 24 hours. If everything is good, simple fix. If not they will replace my unit. Also it doesn’t disable the Z wave that’s connected to it.
One additional thing, in my ST last night after I changed the batteries I was still seeing 0% battery on the new swapped out ones. Once I did this capacitor flush my ST is now showing 100% battery. Feeling like this could be the fix.
keep us updated! I have had to change out the batteries on this lock weekly for far too long. The amazon basics rechargeable batteries will get me to almost two weeks of battery life though!
Here is the update:
I just changed out the batteries yesterday 3/17/19 when they were down to 20%. I didn’t use my best batteries on this test, so I think this is a solution. I again will have to discharge the capacitor as it’s showing only 20% again, but I put brand new batteries in again. I would say this is a success to reset and get everything working again. Basic Duracell batteries lasted almost 3 months on a heavy use front door.

The forum is abuzz with questions about Kwikset z-wave module and battery issues:
I’ve seen three separate topics in the past week on the 910 having all types of issues.

916 zwave here with the same battery drain issue. Hub is about 10 feet from the door. Duracell copper tops last less then a week. However, take the batteries out of the lock and they work just fine in other devices. It almost has to be a reporting issue. I hope this gets fixed quickly, it’s really annoying.
Ok, was just able to prove my point. Went from “battery power to low to operate door”. Pulled battery pack, pressed the button 3 times then held it in while replacing the pack. Door proceeds to do hand check, unlock, relock a few times with smart things app, now reporting batteries at 70%. Something is majorly jacked up with battery reporting.
I wish I found this thread before I decided to switch from Alkaline to the expensive Energizer Lithium everyone is talking about. Is it possible the problem is the batteries here?
Some background on my situation…
I have a Kwikset 912 z-wave lever lock on my garage door to keep guests out and a Schlage deadbolt on the door guests use to get into the house. I got sick of having to change batteries so often so splurged and picked up the Energizer Lithium. They have been amazing in my Schlage deadbolt but apparently completely drained in Kwikset 912 in under 2 weeks. I have had the Kwikset 912 for about a year and never had a full drain issue with the Alkaline batteries.
Unfortunately, I completely neglected to keep the physical key outside of the locked area (I know, won’t make that mistake twice) and had to drill the lock about 30 minutes ago. I ordered a replacement Schlage but would still very much like to salvage the kwikset for some less critical space.
Without sidetracking this thread too much, does anyone know If I can replace the core of the Kwikset 912? I was able to take the drilled piece out but can’t find part numbers or spares anywhere. I called kwikset support and they told me I need to special order the entire external keypad part from Lowe’s or HD. I calling BS on them and am pretty sure the core of this lock is just like any other. Hopefully someone here can confirm and direct me to where I can purchase the replacement part.

I bought a device to rekey my kwikset locks.
Step1 remove the cylinder.
Seems like you should be able to swap cylinders as long as the donor device looks like the other ne you are going to.
Yeah something weird is going on. Rechargeables last a week alkilines last a few months.
