August Smartlock, $250
13 of 36
Okay, you probably don't need an expensive smartlock, and reviews of the August Smartlock have been mixed. But the idea is cool: Since you unlock August with your phone, you can digitally send keys to people who need access to your home. You can even revoke keys for people who you don't want to have 24/7 access.
