Kwikset Kevo (2nd Gen) Touch-to-Open Bluetooth Smart Lock, Works with Amazon Alexa via Kevo Plus, in Satin NickelI really wanted to have kevo work. It had all the attributes I wanted (geo boundary, ability to use my old keys, respected manufacturer, WiFi accessibility). I didn't like that I had to pay half the price of the already expensive smart lock to get WiFi, but again, I wanted it to work...NOTE: I made four videos (referred to below), they are all combined in the single attached video.NOTE: I refer to the kevo installation documentation, but I can't post a link to them (Amazon review guidelines). You can find them with a search for kevo gen 2 installation.How many things can go wrong with a simple replacement of a lock from the same manufacturer? Let's count the ways:1) Unclear instructions on which latch to use.I had to use the "Drive-in latch" instead of the latch with the faceplate. There was not enough room, needed shorter latch (60mm backset). Instructions refer to chiseled or not, in my case the chisel had nothing to do with it. The instructions don't mention the latch with the rectangular faceplate has a 70mm backset which the "Drive-in latch" has a 60mm backset. My previous Kwikset lock had a rectangular faceplate but a 60mm backset.2) Cable did not fit through hole in mounting plate.Instructions say to "route cable through the center hole" on the mounting plate. In the Instruction video at about 2:10 it shows an animation simply pushing the cable connector through the plate. In my case the hole in the mounting plate was too small (and even looks too small in the video, see screen captures "Connector entering plate", "Connector in plate", "Connector leaving plate"). My experience can be seen in the video, "kevo connector bigger than hole".Wanting to give kevo the benefit of the doubt, and the fact that the mounting plate is a simple steel plate where the hole has no significant mechanical or electrical impact, I filed out the hole enough to pass the connector (see the video "kevo connector with modified mounting plate"). Problem solved, I thought, although in my zeal for finishing I may have violated the warranty (but, it's just a little metal, I thought).3) The control shaft in the kevo was (mostly) upside downThe installation video says to make sure the turn piece on the interior assemply is in the vertical position (at about 2:30, see screen capture "Turn piece vertical"). Note the little diamond is pointing up. In my case the turn piece is upside down (see video "kevo turn piece rotation" and screen capture "kevo turn piece upside down"). I thought about turning the latch upside down in the door (it was installed correctly, see "latch is UP"), but I was concerned something else would go wrong and just wanted to test it.In any case this meant that I could not actually mount the kevo interior assembly correctly. At this point I wanted to test it, which meant I had to install the interior assembly upside down on the door.4) The kevo automation sort of works, but even installed upside down the shaft is turned so that it doesn't actually retract the bolt all the way.I tried "handing the deadbolt", following the installation video at about 3:22. In my case I never heard the "long beep" after installing the battery pack, despite holding the button for more than 3 seconds (see video "Handing the deadbolt"). The installation video suggests the beep would happen while holding the button, the written instructions more accurately reflect my experience.Note the installation video shows the deadbolt retracting and extending twice, followed by two green flashes from the LED. For me the deadbolt attempted to retract once, got about 80% closed then whined as it tried to finish. Then it extended followed by a beep and gave a single green flash. So it kinda looked like it worked, but it didn't really work right as it cannot actually retract the deadbolt completely.--------Given all that it may not be reasonable to try again, but as I said I really want this to work. I documented everything, reinstalled my old lock, and now I'm trying to see how to get another kevo and try again. That is, if they don't void my warranty because I modified the mounting plate that didn't actually work with the connector.
