    • Nice and easy
Color: Satin Nickel
Easy installation easy to integrated into our existing security system. Able to keep all the locks keyed the same like they were prior to installing. If you can read instructions and know how to use a screwdriver it will take you less than an hour to install it and get it set up.

    • Simple Way to Make Existing Locks Smart
Color: Satin Nickel
This actually replaced my existing Kevo, so it was a simple installation of swapping out this back panel. It paired easily to my Home Assistant via Zigbee. The device’s batteries last a lot longer than the August Lock. The back panel is solid, though the black plastic panel is a bit flimsy. Also, the placement of the screw on the bottom makes it challenging to install because the door handle is in the way. I’d prefer if the unit was more streamlined and less bulky, for a better look. Overall, this is a great alternative to other smart locks and retains the existing lock look and functionality from the front. Works great with Home Assistant. ... show more

    • Lock/unlock mechanism may stick if the bolt and strike plate alignment is tight
Color: Lifetime Polished Brass
Works great, but wish it could connect directly to wifi without a zigbee hub. Sometimes have problems when temperatures change with season; the motor cannot overcome the friction of the bolt to the door frame when expansion causes some small misalignment between the two. The problem can be resolved by pushing or pulling on the door while activating the lock or unlock mechanism when this happens. I adjusted the alignment of the bolt and strike plate, which seems to have resolved the issue, but if you have a bolt lock that is tight, this product may struggle to lock and unlock the door. ... show more

    • Great product
Color: Satin Nickel
Setup was easy. Works with ZHA. I love the fact that there is no need to change the lock mechanism or the outside unit. My favorite part is you can easily remove the battery pack with no tools in two seconds and your lock becomes an ordinary (dumb) lock with no outside connection, and still looks good. ... show more

    • Louder than a chainsaw and dead after 3 months
Color: Satin Nickel
The media could not be loaded. The instructions are verbose, but fairly usable. Getting it configured "correctly" for left-vs-right doors is confusing at first (mostly a wording and status communication issue) is a bit weird, but fine. Otherwise, it works. Connects just fine to Home Assistant and seems to work. However, it is LOUD. Like... REALLY loud. Like... "power drill" loud. Or "chainsaw". How is it THIS LOUD? I can literally hear it echoing down the hallway of my floor of the apartment building... from OUTSIDE my apartment. How has no one else mentioned how loud this is? ... did I just get a bad unit? Update: 3 months later (note: I replaced the original unit with another that seemed to be slightly quieter), the motor has just stopped functioning. It started sounding a little funny less than a week ago, happily locked yesterday morning when I went to work, but then was no longer working when I got home. No sounds or anything indicating even an attempt to lock/unlock when it is requested to, but it does still seem to be reporting the lock status when manipulated manually. So I guess the motor is just dead. Guess the motor isn't rated for more than 250-300 cycles... ... show more

    • Works Really Well. Fitment and Orientation are Most Important
Color: Satin Nickel
It works really well. Locks and unlocks flawlessly with a solid connection to my smart home. The things to watch for most is the orientation of the lock in relation to the deadbolt mechanism (the manuel doesn't quite make this clear and the lock doesn't work in the wrong orientation)... Other than that set up is easy it looks nice fits right into the door without really changing anything and without having any weird looking retrofits. ... show more

    • Cautiously optimistic
Color: Satin Nickel
Based on the other reviews in withholding final judgment. Right now though I easily installed this device to am existing Kwikset deadbolt. It is connected to my Home Assistant instance via ZHA for a few days now without issue. It responds much faster than the August lock I tried out (likely bc it works without a cloud connection). Couple things though. First it is recognized as a gen 1 when I connected it and the box showed a manufacture date of 2017. Second i was sold an open box unit rather than a new unit. Amazon did give me $20 back so I'm satisfied. The batteries in the box were corroded and weathered by poor storage conditions. The lock hardware itself looks ok. I pulled the zigbee board out and it is in good shape. Even being opened, it was obviously unused so I think it'll all be ok. Yes it's loud and you have to take the face plate off to replace batteries but...it ended up only costing $80 so again, I'm ok with some design shortcomings. A few days is not long enough to evaluate battery life but I will update my review if that looks to be an issue. Overall, so long as it lasts, I do not have any major complaints considering the cost. ... show more

    • Good replacement if you got stuck when amazon killed their cloud cam.
Color: Lifetime Polished Brass
I had the Convert lock v.1 and used it for years with the cloud cam. Amazon discontinued the cloud cam, and they sent me a zigbee enabled Alexa to and camera to compensate for the loss (a really class move that keeps me a loyal customer). Anyway, the new Alexa and cameras work great, but the old lock would not pair with the Alexa. I got this version 3.0 and it installed using the same door hardware as the 1.0, and within a minute, I paired it to my Alexa and now have control of my door again. I highly recommend this as a replacement if you are in the same situation. ... show more
