The best smart locks add an extra layer of security and convenience to your home. You can remotely open and lock your door, see if it's closed or ajar from your phone, and share digital keys with guests or family members from anywhere with an internet signal. The hardest part is getting started once you dump all of the hardware out of the box.
I spent this weekend upgrading my existing deadbolt with the Aqara U100 smart lock ($229, Amazon). This completely replaced my standard lock, unlike an interior conversion smart lock such as those from August or Wyze. However, I was surprised at how painless the process was.
