Overview

What the August Smart Lock Pro is

The August Smart Lock Pro reimagines home entry by transforming your existing deadbolt into a connected, intelligent access point without requiring you to replace your exterior hardware or change your keys. Designed to fit over most standard deadbolts, it preserves the look of your door while adding robust smart capabilities underneath. At its core, the lock delivers reliable automatic locking and unlocking triggered by your smartphone's proximity, so you can walk up to your door with arms full of groceries and have it open before you reach for a handle, then lock itself securely behind you once you're inside. The pro version refines the motor and locking mechanism for faster, quieter operation, addressing one of the most common complaints about earlier smart lock generations and making the experience feel seamless rather than gadget-forward.

Where the August Smart Lock Pro truly distinguishes itself in the home security space is through its granular control over who comes and goes. Homeowners can issue virtual keys to family members, cleaners, dog walkers, or houseguests, each with customizable schedules and access windows, then revoke that access instantly from the companion app if circumstances change. Every entry and exit is logged with a timestamp, giving you a detailed activity history so you always know when your teenager got home from school or when the contractor arrived for a repair. The lock also integrates with August's optional Doorbell Cam and View products, as well as third-party security platforms, allowing it to function as one node within a broader layered home security setup rather than an isolated gadget bolted onto your door.

Connectivity and compatibility round out why the August Smart Lock Pro remains a staple recommendation in smart home security circles. It supports Wi-Fi directly or through an optional bridge, enabling remote locking and unlocking from anywhere, which is particularly useful for letting in a trusted visitor while you're away or double-checking that you actually locked up before leaving town. The lock plays well with major smart home ecosystems, responding to voice commands through Alexa, Google Assistant, and Siri, and it supports auto-unlock geofencing that adapts to your daily patterns. Battery life is engineered to last several months per charge, with low-battery alerts sent well in advance, and a backup power option via USB-C ensures you're never locked out due to a dead battery. Altogether, it offers a thoughtful blend of physical security, convenience, and oversight for anyone looking to modernize how their front door operates.
