August Smart Lock Pro + Connect Hub - Wi-Fi Smart Lock for Keyless Entry - Works with Alexa, Google Assistant, and more - Silver $160

Upgrade your existing deadbolt: August smart locks fit on the inside of your door, making your regular deadbolt smarter, more secure and way more convenient. Keep your keys just in case (but you won't need them)
Grant access with the August App: Forget key copying. Quickly and easily share permanent, scheduled or temporary access to your home with friends, family and other people you trust, and never put a key under the doormat again
Easy to install on any door: Even if you're not so handy, installation only takes about 10 minutes. August locks fit perfectly over most single cylinder deadbolts
Auto-Locks and Unlocks: Auto-Unlocks as you get home for totally hands-free unlocking. With Auto-Lock and DoorSense, your home automatically secures once your door is closed, or after a set amount of time (optional feature)
Works seamlessly with your smart home: Included Connect Wi-Fi hub allows your lock to work with your favorite voice assistant, including Amazon Alexa, Google Assistant, Apple HomeKit, Samsung SmartThings and more
Renter-friendly: Renting or leasing your place. Home improvement isn't just for homeowners. Modernize your apartment's lock and then take it with you when you move -- the old deadbolt thumbturn can be easily reinstalled
Keep your home's curb appeal: Get smart lock functionality without changing the look of the outside of your front door. August smart locks are installed only on the inside of the door, so the design for your front door doesn't have to adapt
Add a keypad for use with codes: For phone-free moments, connect a Smart Keypad (sold separately) to unlock the door with unique codes. Great for small kids, the housekeeper, the dogwalker, or other one-time visitors
