Kwikset SmartCode 910 Z-Wave Plus Touchpad Electronic Deadbolt featuring SmartKey Security and Avalon Handleset with Tustin Right Handed and Left Handed Lever Works with Alexa via SmartThings, Wink, or Iris in Satin NIckel

Here's the secret to easy pairing (and not covered in the instructions): Before anything else, pair the lock with your hub.Here's the reason. These locks require "secure" pairing with the hub and that requires a stronger than usual signal from the hub. If you wait until lock is installed, signal may be strong enough to pair but not to securely pair. This leads, as I learned from sorry experience, to squirrelly behavior. Took a very knowledgable tech person from my z-wave hub manufacturer to figure this out and had to look at some fairly obscure hub data to see lock was paired but not securely paired..So, the details of how to do the "first thing" pairing. Grab the smart end of the lock (the piece that goes inside the door) out of the box. Pull off the shiny plastic decorative cover to reveal the battery holder and programming buttons (not to be confused with the pin-entering buttons on the lock component that goes outside the door). Pull out the battery holder, insert 4 AA's, and reinsert the battery holder. (Make sure arrows at top of battery holder point toward where the door will eventually be located.)Now lay the lock component, programming button side up, right next to your hub. Let them touch, why not. Put your hub in Inclusion mode (your hub instructions will explain how). ONLY THEN, put the lock component in Z-Wave inclusion mode by pushing the upper left "A" button once (For ZigBee instead of Z-wave, check directions buried in middle of installation instructions; on my model, I push the upper right "A" button 4 times.) Leave that third button, bottom center, alone: you will use it later to program pin codes to operate the lock manually.Hub should then quickly find and include your lock. Have yet to have this fail.Now, pick up the instructions that came with the lock and start the physical installation. Your lock has been paired even if you pull out batteries during installation, wait a couple of days, or whatever.Over the years, I have put in more than a half dozen of these in two houses, two different hubs. So, I obviously like them. But there have been many hours of trying to include them, exclude them to try again to include, do factory resets, and such. Until I learned the preceding trick. Now, I can change out an old bolt lock and put in the new one in 10 minutes.

I got this as part of my 2Gig Go Control alarm system install. I would assume that this works with any alarm system or hub that is capable of talking "Z-Wave". This has worked wonderfully for us. No more getting locked out or forgetting the keys, we just hit the lock button on the way out and punch our entrance code when we return. Its so easy that about a year ago my now 5 year old started punching her own code in when we would get home.Since this is a Z-wave device, you can pretty much control it via your alarm system's app or automate it so that it locks automatically when you set the alarm or unlock automatically when you disable the alarm. As far as batteries go, they last about 6 months or so and that's with us constantly going in and out. I have been tempted to get more for the other doors (currently it resides in our garage door), but still mulling that over.Update: 05/19/16While fixing the door handle that "lives" underneath this deadbolt, I realized that this device has Kwikset's re-key technology. It had never occurred to me to re-key this device. I was able to re-key it and we can now use the same set of keys as the rest of the house. Not a big deal as you almost never use the key hole, but its just another bonus feature to this device.As for the device, I recently replaced the batteries with some new lithium batteries and wow, big difference. I was starting to wonder if this thing was going out since occasionally it seemed to make funny noises while locking or unlocking. I was never sure if it was just the batteries or this thing slowly giving out. For us we honestly use it a lot, so with these new set of batteries, it is working as if new. We love it! Good luck!

I've had this lock for about a month now. Installation was simple. The smartkey feature made it easy to re-key it to match my existing Kwikset locks.Programming is fairly simple. You can program and operate it Without a Z-wave controller system. Without a Z-wave system you can manually program two access codes. With a Z-wave controller system you can program up to 30 codes. The lock creates an "Alarm" device as a sub-device on your Z-wave controller which relays a long list of events you can use as triggers.For example, when a user code is entered to unlock the door and it's night, I have the entryway light come on. When the door is locked from the outside, I turn off all lights in the house.You cannot operate it with a handheld controller. You need to have a computerized controller like Mi Casa Verde or Homeseer and your Z-wave interface or USB stick needs to have the latest firmware. I had to update my WDUSB-10 USB stick in order to make it work.While this lock has only 5 buttons vs the 10 buttons on the Schlage lock, The Schlage lock allows only 4 digit combinations where the Kwikset allows 4 to 8 digits.4 to 8 digit codes from 5 buttons = 390,625 permutations4 digit codes from 10 buttons = 10,000 permutationsUpdate: I recently bought another one for my garage side door. The product has been updated since the first one I bought. The new unit is functionally identical but the build quality seems much better now. Not that it was bad before but this one seems sturdier overall.
