August Smart Locks: Which Model and Add-Ons You Need

August made its name with smart locks you can fit without changing the outside of your door. Instead of replacing the whole lock, an August lock replaces only the thumbturn on the inside, the little knob you twist to lock the deadbolt. That style is called a retrofit lock: your old key still works from the outside, and the lock itself becomes controllable from your phone, voice assistant or keypad. If you searched for an “augest smart lock,” this is the family you were looking for.
The six items below include three August locks, one lock-and-bridge bundle, a keypad and a Wi-Fi bridge; the main differences are whether Wi-Fi is built in and whether a keypad comes in the box.

Yale August Wi-Fi Smart Lock
Best for: Families wanting fingerprint entry in one box
Pros
- Built-in Wi-Fi, no hub needed
- Keypad Touch with fingerprint scanner
- DoorSense and batteries included
- Keeps your existing deadbolt
Cons
- Keypad relies on Bluetooth range
- Uses Yale Access app
The Yale August Wi-Fi Smart Lock with Keypad Touch is the most complete kit here. The box includes the August Wi-Fi Smart Lock, a DoorSense sensor, mounting hardware, batteries and the Yale Keypad Touch. Like every August lock, it installs on the inside of your door over your existing deadbolt, so you keep your keys.
The keypad adds a fingerprint scanner, which the listing says unlocks with 99% accuracy, plus custom entry codes you can share with family, friends or guests. It mounts anywhere within Bluetooth range of the lock. Built-in Wi-Fi means no extra hub or bridge is needed, and the Yale Access app shows a 24/7 activity feed so you can see when the kids got home. The listing notes existing August Home account holders can use their current login.
This is the one to pick if you want a key-free, phone-free setup straight out of the box, or if you are buying a smart lock as a housewarming gift and want everything included. It also carries Yale branding and uses the Yale Access app rather than the August app.

August Home
Best for: First smart lock with built-in Wi-Fi
Pros
- Built-in Wi-Fi, no bridge
- Works with Alexa, Google, HomeKit, SmartThings
- About 10-minute install
- Auto-Lock, Auto-Unlock, DoorSense
Cons
- Keypad sold separately
The August Home Wi-Fi Smart Lock (4th Generation, matte black) is the standalone lock with Wi-Fi built in. The listing says installation takes about 10 minutes and that it fits over most single-cylinder deadbolts. A single-cylinder deadbolt is the common type with a key outside and a thumbturn inside.
It supports Auto-Unlock as you arrive, Auto-Lock after the door closes or after a set time, and DoorSense, which tells the lock whether the door is actually shut. The August app lets you share permanent, scheduled or temporary access. Built-in Wi-Fi connects it to Amazon Alexa, Google Assistant, Apple HomeKit and Samsung SmartThings. The box includes the lock, batteries and mounting hardware; a Smart Keypad is sold separately.
This is the easiest August lock for a first-time buyer who wants remote control without extra hardware. If you want to know how retrofit locks compare with a traditional deadbolt lock, our guide explains the basics.
August Home Smart Lock for Bluetooth-First Entry
Best for: Rental hosts and guests without phones
Pros
- Unique, expiring key codes
- One-touch locking
- Bluetooth setup in minutes
Cons
- Needs an August lock
- Must mount near the lock
August Home

August Home Smart Lock Pro
Best for: Buyers wanting lock and bridge together
Pros
- Connect Wi-Fi Bridge included
- DoorSense sensor and batteries included
- Auto-Lock and Auto-Unlock
Cons
- Very short feature list
- Keypad sold separately
Best for: Phone-based entry with Bluetooth setup
Pros
- DoorSense sensor included
- Scheduled or temporary guest access
- Screwdriver-only install
Cons
- Needs Connect bridge for remote access
- Keypad sold separately
The August Home Smart Lock in dark gray is the 3rd Gen model. It attaches to your existing deadbolt on the inside of the door and installs in under 10 minutes with a screwdriver. The box includes the lock, a DoorSense sensor, four AA batteries, a lock adapter and mounting hardware, and the listing states a one-year manufacturer warranty.
It supports Auto-Unlock, timed Auto-Lock and guest access you can limit to weeks, hours or minutes. The key difference: remote access and Alexa integration require the August Wi-Fi Connect Bridge, sold separately. Without it, the lock talks to your phone over Bluetooth when you are nearby. The listing also mentions “110 to 240 volts,” which likely refers to the bridge since the lock runs on AA batteries; the listing does not make this clear. It requires iOS 9.0 or Android 5.0 or higher.
Choose it if you mostly want to unlock from your phone at the door. Add the bridge later if you want remote control.
August Home Smart Lock Pro with Connect Hub for a Ready-Made Bundle
The August Home Smart Lock Pro bundle combines the Smart Lock Pro with the August Connect Wi-Fi Bridge. Included are the lock, the bridge, a DoorSense sensor, four AA batteries, a lock adapter and mounting hardware, with a one-year manufacturer warranty.
The listing is brief. It says you can control and monitor your door from anywhere, see who comes and goes, keep your existing lock and keys, and use Auto-Lock and Auto-Unlock. The title names Alexa and Google Assistant. It also advises measuring your door’s backset, cross bore and thickness to check fit; those are the distances and hole sizes that decide whether a lock fits your door.
This suits buyers who want remote access from day one without buying the bridge separately. The 4th Gen lock gets the same result with Wi-Fi built in, so compare the two.
August Home Smart Keypad for Guests and Rentals
The August Home Smart Keypad is an add-on for an August lock. It connects over Bluetooth and mounts near or on the door, within about 10 feet of the lock. Through the August app you create unique key codes for friends, cleaners or guests, and codes can expire automatically at checkout.
Pressing the August logo locks the door with one touch, handy when you leave without your phone. It measures about 1 x 2.9 x 0.9 inches. It is ideal for vacation rental hosts or families with kids who do not carry phones. For standalone code locks, our keypad door lock set guide covers a different approach.
August Home Connect Wi-Fi Bridge for Remote Access
Best for: Adding remote access to older August locks
Pros
- Remote lock and unlock
- Alexa, Google Assistant, Siri control
- Entry and exit alerts
Cons
- Needs a wall outlet
- Warranty only for US and CA
The August Home Connect Wi-Fi Bridge plugs into a North American wall outlet and links a Bluetooth August lock to your Wi-Fi. That unlocks remote locking and unlocking, instant entry and exit alerts, and voice control through Alexa, Google Assistant or Siri.
It includes the bridge and a getting started guide, with a one-year warranty that the listing says only applies to US and Canadian customers. It suits owners of the August Home Smart Lock who want to add remote features. Wi-Fi locks such as the 4th Gen and the Yale kit do not need it.
How to Choose the Right August Smart Lock
Wi-Fi built in or bridge. A bridge is a small plug-in box that connects a Bluetooth lock to your home Wi-Fi. The Yale August kit and the 4th Gen lock have Wi-Fi built in. The Smart Lock needs the Connect bridge, and the Smart Lock Pro bundle includes it.
Keypad or no keypad. Only the Yale August kit includes a keypad, with fingerprint unlock. Others need the Smart Keypad separately.
Smart home platform. The 4th Gen listing names Alexa, Google Assistant, Apple HomeKit and SmartThings. If your home runs on Z-Wave instead, our Z-Wave smart lock guide covers that route.
Door fit. All these locks retrofit over a single-cylinder deadbolt. Measure your door’s backset, cross bore and thickness first.
