The second-gen Kevo looks and works almost exactly like the first-gen version. You can still open it with a tap if it detects your phone outside the door. There are some subtle improvements on the inside, though, including an easier installation and a sturdier design.
Another optional upgrade: the $100 Kevo Plus Wi-Fi gateway. Plug it in and pair it with the lock, and it'll relay the lock's signal to the cloud. That'll let you monitor and control the lock from your phone when you aren't at home.
The new Kevo is also designed to resist brute-force attacks, including a specific one that works on the first-gen model. We tried it again this time and marred the hell out of the lock in the process, but the Kevo wouldn't budge.
The new Kevo costs $230, a slight increase over generation one. That's a little disappointing, especially given that the key fob accessory no longer comes included. Still, that touch-to-unlock functionality is pretty tempting... read our full review to see if we think it's worth it.
