The August Wi-Fi Smart Lock (4th Generation) and August app allows you to remotely lock or unlock your door, check door status, grant virtual guest keys and always know who’s coming and going. Connected out of the box with built in Wi-Fi, the August Wi-Fi Smart Lock is easy to install and attaches to your existing deadbolt so you can keep your original keys.
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 and aren’t much bigger than your original thumbturn.
AUTO-LOCKS AND UNLOCKS: August Wi-Fi Smart Lock is able to Auto-Unlock as you get home for totally hands-free unlocking (optional). With Auto-Lock and DoorSense, your home automatically secures once your door is closed, or after a set amount of time.
WORKS SEAMLESSLY WITH YOUR SMART HOME: Built-in Wi-Fi allows your lock to work with your favorite voice assistant, including Amazon Alexa, Google Assistant, Apple HomeKit, Samsung SmartThings and more.
AWARD-WINNING SMART LOCK YEAR AFTER YEAR: Voted CNET Editor’s Choice two years in a row (2020/2021), Best Smart Lock by Good Housekeeping (2021), Best Smart Lock by Tom’s Guide (2021).
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 your 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.
FACE OR FINGERPRINT ID FOR EXTRA SECURITY: Use your phone’s biometric recognition for two-factor authentication (optional).
REQUIREMENT: Free August app for iOS or Android iOS (iOS or Android smartphone required), Wi-Fi internet connection (802.11 b/g/n 2.4GHz or 5GHz)
