August Smart Lock is a popular keyless, smartphone-controlled smart lock designed to modernize home security and simplify everyday access to your front door. Instead of traditional metal keys, it lets you lock and unlock your door using your iOS or Android smartphone, Apple Watch, or connected keypad, while still allowing the use of your existing physical key if needed. The lock attaches to the inside of your existing deadbolt, so installation is quick and doesn’t require changing your exterior hardware, making it renter-friendly and easy to set up with just a screwdriver.

One of the standout features of the August Smart Lock is its smart functionality: with the accompanying app, you can control your door from anywhere, track who comes and goes with activity logs, and send secure virtual guest keys to friends, family, or service providers with customizable access durations. The lock also supports auto-lock and auto-unlock — using geo-fencing to automatically unlock the door as you approach and lock it after you leave — giving you a seamless, hands-free experience.
