Cool idea but still needs work. Fob keys are not always working and the iOS app hasn't been working well with me since ios9 and I've had nothing but headaches. The trick is kinda the same process as taking out your keys. I just open the Kēvo app and I walk up to the door and finally I was able to get it to unlock. Leaving the phone/fob key in you pocket has been a big headache and it doesn't always work for me. Installation is really easy and the end results make you feel like you have an awesome looking house especially when people ask how you opened the door without keys. It's a cool idea it's just not ready yet and needs improvements.
