I'm not looking at it that way. Keys are just another thing to keep in your pocket, but your phone is always with you. The way I carry stuff in my pockets, my phone is always more readily available than my keys so taking it out is a natural motion. You can, however, argue that taking out your phone, launching the app, and clicking a button is as an aggregate action more involved than just inserting and rotating a key. I think the real benefits become apparent when you realize all the stuff this enables you to do: your spouse/friends no longer get locked out, you never have to do the "did I lock it or not?" dance, and if they provide an API, you can sync a lot of stuff when your door opens, like turn on appliances, trigger a network setting, boot your computer, text your friends, anything really.
