Apple Home Keys will let you unlock your front door with your iPhone

Apple has let use your iPhone and Apple Watch as digital car key. Come iOS 15, a new tool called Home Keys will let you do the same with a compatible smart lock to your home. It's one of several smart home-related features Apple showed off during WWDC 2021. Once you're inside your home, tighter integration between HomePod and Apple TV devices will allow you to control tvOS by issuing voice commands through one of Apple's smart speakers. For those who own both an Apple TV 4K and one or more HomePod mini speakers, the company will let you pair those devices together for a better audio experience.
