They don't really want to unlock your house and your car, just one of them. Assuming that you don't have some secure alternative for receiving packages. I don't think they expect (or want) every customer to use one of these options. I wouldn't use either service since my porch is relatively secure and packages can be left out of sight -- I have a porch-cam, but have never lost a package to theft. I don't think I'd be comfortable giving Amazon the ability to unlock my house, but maybe my car. For that matter, I wouldn't want any kind of cloud-connected lock that gives any remote unlock capability. I do have an electronic keypad lock, but I like knowing that it can only be unlocked locally.
