About the August Smart Lock Pro + Connect

A remote-control smart lock that protects your home

I've lived in a number of houses and apartments during my lifetime, and my locks have invariably been flimsy, unreliable, difficult to operate, or all three. The August Smart Lock Pro offers a pretty compelling alternative to just about any door lock I've used in the past.

A remote-control smart lock that protects your home

August Smart Lock Pro for keyless home entry

Control access to your home with the August Smart Lock Pro + Connect.

I've lived in a number of houses and apartments during my lifetime, and my locks have invariably been flimsy, unreliable, difficult to operate, or all three. The August Smart Lock Pro offers a pretty compelling alternative to just about any door lock I've used in the past.

The Smart Lock can be controlled via Bluetooth and your smartphone, more or less within line of sight. This bundle expands your remote control options by including the August Connect wireless bridge. The Connect plugs into a standard wall outlet and lets you monitor and control the lock even when you're at work or out of town.

No more "oops, I forgot to leave a key"

Does the babysitter or dog-walker need to get in while you're away? Instead of hiding a key under the doormat (or even worse, forgetting to leave one at all), use the free August app to generate one-time access codes. Or, create a scheduled window of time that they can come in. Using just their smartphone, they'll have secure access anytime you want them to, and no access when you don't.

More details on the August Smart Lock Pro + Connect

Mark G.
The August Smart Lock Pro + Connect replaces these items:

Product Research


Overview: The August Smart Lock Pro (3rd generation technology) installs over your existing single-cylinder deadbolt lock and lets you lock and unlock your door with your smartphone. With Smart Lock Pro, you no longer have to fumble for keys, as the Smart Lock Pro unlocks the door as you approach and locks it as you leave (Auto-Unlock/Auto-Lock). You can grant temporary access to others ("virtual keys"), and use your smartphone to keep track of who comes and goes anytime of the day and night. Smart Lock Pro replaces only the interior portion of your deadbolt, allowing you to continue using your traditional key whenever you want. You can also manually turn the deadbolt by hand from the inside if you don't want to use your phone. Smart Lock Pro is powered by 4 pre-installed "AA" batteries (included).

Connect: Included with Smart Lock Pro is the August Connect, which uses your home's Wi-Fi network and Internet connection to control the Smart Lock Pro from anywhere through the August Home app. Connect also allows you to control the Smart Lock Pro using voice commands through Alexa, the Google Assistant, or Siri (Apple Home Kit ready). It is also a certified Z-Wave Plus smart home product. The Connect Wi-Fi bridge is 2-3/8" square x 1-1/2" deep, and plugs into a standard AC outlet, and must be within 15 feet of the Smart Lock Pro to connect.

Compatibility: August Smart Lock Pro is compatible with standard single-cylinder deadbolt locks that are mounted and operate independently of the door handle. It does not work with mortise, rim cylinder, or interconnected locks. Click here for the August Deadbolt Compatibility List. To install the Smart Lock Pro, you will need to remove the interior portion of the deadbolt, and replace it with the Smart Lock Pro unit. Three adapters are included to fit most deadbolts to the Smart Lock Pro mechanism. Installation requires a standard Phillips screwdriver, and typically takes less than 15 minutes.

Smartphone Integration: The August Smart Lock Pro interacts with your smartphone or tablet via Bluetooth (v4.0) and the August Home app. The app must be loaded to the phone of all users, including guests. As long as your smartphone is range, you can lock or unlock the door from the app. Each time the door is locked or unlocked by a user via the app, a notification is sent to selected users, and the event is logged to the app. The August Home app is compatible with iPhones running iOS 9.0 or later, and with Android devices with Bluetooth 4.0 and running Android 5.0 and up.

2 Factor Authentication: To keep your August Smart Lock Pro and account secure, August uses 2 Factor Authentication in order to access the app. When signing up, you will need to validate both your email and phone number, and a token is stored on your account and device. If you try to sign in on a new device, you will have to authenticate your account using both your password and with a code sent to either your email or phone number.

DoorSense: Included with the Smart Lock Pro is the DoorSense module, which can sense whether or not your door is open or closed. A magnet in the DoorSense module interacts with the SmartLock when the door is closed. You can view the condition of the door (open or closed, locked or unlocked) on the August Home app. DoorSense can be surface-mounted or flush-mounted next to your deadbolt, and requires only a screwdriver to install. (Flush mounting also requires drilling a 5/8" hole in the door frame.) You will need to calibrate the Smart Lock Pro after installation to insure the functionality of DoorSense.

Smart Keypad: The August Smart Keypad is an accessory for the August Smart Lock Pro. It attaches to the wall outside your home, and allows you operate the Smart Lock Pro without a smartphone. Unique codes can be generated for each individual, including guests or service personnel. The unique codes tie your guest's name to each entry so you can keep track of who comes and goes. The Smart Lock Pro and Smart Keypad can create a 24/7 log of who entered your home and when.

August Lock Users: There are several levels of users of the August Home app. The Home Owner is the individual who originally set up the lock and has access to all of the settings and can invite (and delete) guests. A Lock Owner has all of the same access to the settings and guest lists. A Guest can lock and unlock the Smart Lock Pro at any time, but cannot change settings or invite other guests. Access types for Guests include: Always, Recurring, and Temporary. The account of each Owner or Guest can be set up whether or not to trigger notifications when that specific user operates the lock.

Customer Q&A

2 questions already asked

Installed today and it works from the inside (while testing) but does not work from the outside. Why?

Did you call August? They were really helpful for me. My suspicion is that the battery in the unit might be weak. I would replace it. Reboot router and the like too just to make sure that it is connected to your home wifi. I would reboot my phone to make sure that my blue tooth is working properly. Is your wifi reaching past the front door? It can be a lot of things. I know I had some setup issues and August helped me get them resolved. My lock unlocks flawlessly using siri, Apple Watch, or my phone. I hope you get it resolved because it is a pretty handy gadget.

It looks like there's no keypad... how do temporary keys work (say, for pet-sitters and the like?) Thanks!

You send invite through the app to your pet-sitter or guess. You can define the time frame of access that you are giving to users, however, everyone who use this lock needs to install the app in order for them to gain access to the lock.
[ Clark  Feb 21, 2020 ]
They would need to install the app on their phones. You can then add them to the household with access by date and time.
[ James  Feb 20, 2020 ]
You grant temporary access through the August App. You can set times, days,etc. The end user would need the app to unlock/lock the door on their smart phone. For emergencies you can unlock the door remotely as well as lock it. There is an optional keypad if that is your preference.
[ John  Feb 20, 2020 ]
The keypad is a separate accessory.
[ WAYLAND  Feb 20, 2020 ]
They're given access through the August smartphone app.
