Wow, this was a challenging install and set up. I replaced a couple Kwikset keyless deadbolts with 2 of these. I think there are a few flaws that are noteworthy. First, the sound that occurs when pressing keypad is very soft. I emailed customer svc, and they told me there is no way to change it. I think the company would do well to fix that in next generation; currently, it is a significant hindrance, as the keypad seems irregular in its response to my deliberate pressing of the number buttons. I have had to enter the number code 2 or 3 times to get it to work. The actual install went smoothly. Reasonable instructions. The 2nd one took me 15 min, while the first took 45. The best part of these locks is their ability to connect directly to WiFi without an additional home management device (Nest, Apple Home). The phone app seems straightforward and helpful, notwithstanding the tech issues below. I found the shape of the deadbolt itself to be suboptimal. While it is a straight deadbolt, the strike plate on the door must be perfectly aligned for it to work. One of the doors (with a striker plate to accept the deadbolt that is quite standard, and slightly larger opening than striker plate supplied) has some play in how tightly it closes. If it closes 75% (the retracting door latch just catches the lower strike plate), it would not close with battery operation. Instead, even with manual turn, it encountered significant friction. And when I pushed door firmly closed, and (separate, round doorknob) handle latch engaged fully, it would catch or have excessive friction on the outside edge. Since I wanted to take advantage of the remote access capability of this lock, I took the deadbolt for each LockState lock to a machine shop, and had the brass deadbolt ground down into a more tapered (think of the tip of a bullet) nose. I had to do this 3 different times to get optimal function. The Kwikset 914 that I replaced has a deadbolt that tapers down very nicely, and allows friction-free movement of the deadbolt. I THINK THIS IS SOMETHING THAT LOCKSTATE SHOULD FIX AT THE MANUFACTURING STAGE, SOON, AND PRIOR TO 'NEXT GENERATION'. The web interface is reasonable, but there could be much improvement in the FAQ portions. Tough to make sure the wifi capability is engaged. Also, with 2 locks, it's a bit tricky figuring out how to make sure a newly-added code gets added to both doors (hint- add a new user, pick the device/door, and then go back and edit, adding a second 'door'). And do note that there is a $0.99 per month charge for each lock if you use the wifi capability. It then costs $3 per month to be able to get text messages, which can be sent to you anytime the door is accessed. You can get a report on the web interface however, without charge, it appears. The wifi, App, and remote functions seem good after a very long day getting these 2 locks installed, deadbolt ground down, and web interface installed, and user/ guest accounts being added. I'm fairly handy, and I'm a bit embarrassed to state that I spent about 6-7 hours on the install of these 2 locks (including 3 trips to a friendly machine shop to grind the deadbolts into a taper so the bolts would move smoothly. Finally, I installed Everyready Lithium AA batteries to minimize the interval that they need to be replaces. ADDENDUM 7-3-19: I took these things out after a couple weeks. They were so temperamental, and the locks did not close properly. They just weren’t worth the hassle. I put the Kwikset locks back in. I don’t even use them anymore. I did not spend any time going to see if the manufacturer had updated these locks anyway, so you might want to review their current product.
