How Do August Smart Locks Work?

August Smart Lock ProAugust Smart Locks differ from many other smart locks in that you don’t have to replace your entire deadbolt. You only have to make minor modifications to the interior of your existing deadbolt (but the caveat is that August smart locks only work with certain deadbolts).

Once you install an August Smart Lock, you don’t have to use your house keys to lock or unlock your door — the smart system uses Bluetooth technology via your smartphone to operate your door lock when you’re in close proximity to your house.

But if you want to be able to remotely lock or unlock your door from anywhere, you can sync the August Smart Lock with their Connect WiFi Bridge, which is included in some of their packages (or you can purchase it separately).

The August Home app lets you control your smart lock settings and assign digital keys for other people who need access to your home. You can see who comes in your home (and when). But if you don’t want to hand over WiFi keys to others, you have the option of installing the add-on keypad that allows you to assign temporary PINs to house keepers, pet sitters or anyone else who needs access to your home on an as-needed basis.

Deadbolt Compatibility

August Smart Locks are only compatible with single cylinder deadbolts. The image below can help you determine whether your existing lock is compatible. You can also find a list of compatible deadbolts on August’s website.

What Do People Think Of August Smart Lock?

Here’s a sampling of some customer reviews we found online about the August Smart Lock Pro + Connect model.

Positive Reviews

It’s cool that I can unlock my door from anywhere In the world with WiFi. Works well with Alexa and getting alerts when my wife and kid get home is awesome. Locks automatically when you leave and unlocks on its own when you arrive. Go Keyless! – Luis, Best Buy 10/2019

The new 3rd Gen lock is a nice leap forward. It allows for Zigbee control, giving access to a Smartthings Hub. I really the fact, that you cannot see that I have a smart lock from the outside. The door sense, at first, I didnt think it added much to the Smart Lock, but I have since changed my mind. I have a door that can be a bit stubborn in the winter to stay closed, and this allow me to know when it is fully closed, or the screen door pushed it open, when I closed it. – theduck71, The Home Depot 2/26/2019

Negative Reviews

It serves it purpose for unlocking the door when I arrive but doesn’t auto lock unless you set the timer instead of locking when you leave, also the bridge keeps disconnecting so you can’t check to see if it’s locked from anywhere and you can’t let people in when your not around. – Xavire, The Home Depot 10/8/2019

A smart lock that out of the box only really works with 4 different (obscure) lock manufacturers. All of the national (US) brands will require adapters (ordered separately) and technical support as the diagrams that come with the unit leave a lot to be desired. All in all, I had it for one day. After realizing it wasn’t ready for prime time, and dealing with their tech (Language barriers the size of Montana, & that’s when you’re not cycled through the call queue several times requiring multiple call backs) the entire experience left me more than comfortable with a regular “old” lock and key. – PerseveringParent, Best Buy 9/2019
