The Kwikset Kevo can make locking and unlocking your door quick and easy -- when it works, that is. At first glance it doesn't look much different from a normal deadbolt, but if you touch it, the lock will light up, giving you visual feedback as to whether the door has been unlocked or not. In tests CNET says the Kevo worked, "never once letting us in when it shouldn't have." And setting it up is pretty "straight forward" according to Gizmodo, provided you're only swapping out your old lock for the Kevo -- if you're installing it on a brand new door, they say you should be "rated Bob Villa-class." For CNET, though, setup of the actual device was hit or miss, and it took them "multiple attempts" to get it calibrated. Gadget Review also ran into issues in regards to distance, finding they needed to be "within 12-18" inches to make the door unlock quicker. The companion app includes powerful tools like an entry log and the ability to hand out temporary e-keys to friends and family -- but only if they're iOS users, since the Kevo doesn't work on other devices. If you're the type who wants your door to be connected like everything else in your life the Kevo is certainly promising, but limited device support, a quirky setup process, and a $219 price tag means most are better off sticking with a good old fashioned key.
