August Wi-Fi Smart Lock (4th Generation) – Retrofit Smart Lock with DoorSense
Upgrade your existing deadbolt without replacing it. The August Wi-Fi Smart Lock installs in minutes on the inside of your door, so you keep your original keys and your exterior door hardware stays exactly the same.
Built-in Wi-Fi — No Bridge Required Remote access is ready right out of the box. Lock, unlock, and check your door status from anywhere via the August app — no additional hub or bridge needed.
DoorSense Technology August's exclusive DoorSense sensor tells you whether your door is fully closed and locked — not just one or the other. Get smart alerts any time the status changes, so you're never left guessing.
Auto-Lock & Auto-Unlock Set the lock to secure itself automatically after the door closes or after a timer of your choosing (up to 30 minutes). Auto-Unlock detects when you arrive home via your smartphone and unlocks the door hands-free.
Virtual Guest Keys Send secure, shareable keys to family, guests, or service providers directly from the app. Set permanent, scheduled, or time-limited access — and revoke it just as easily.
Works With Your Smart Home Compatible with Amazon Alexa, Google Assistant, Apple HomeKit (Siri), and Samsung SmartThings. Control your door with voice commands or build it into your home automations.
