About this product
August Smart Lock Pro 4th Generation is the bestselling retrofit smart lock — it attaches to the inside of your existing deadbolt without replacing the lock or the exterior hardware, so your physical keys still work and your renters/visitors don't see any smart lock from outside. The 4th gen adds built-in Wi-Fi (previous gens required a separate bridge), Apple HomeKit + Alexa + Google compatibility, auto-unlock when your phone arrives home, and touch-to-lock from inside. Battery powered with 3-6 month battery life. The smart lock for renters and historic-home owners who can't replace the deadbolt.
