Features

  • YOUR LOCK ON THE OUTSIDE, A SMART LOCK ON THE INSIDE: August smart locks replace the thumbturn on the inside of your door, making your regular deadbolt smarter, more secure and way more convenient. Keep the outside of your door the same, and your keys just in case (but you wont need them).
  • GET IN AND OUT WITH THE AUGUST APP: No pockets? No problem. Lock and unlock your door with the August app on your phone or Apple Watch, and leave your house keys behind.
  • AUTO-LOCKS AND UNLOCKS: Auto-Unlocks as you get home for totally hands-free unlocking -- great for when your arms are carrying kids or groceries. With Auto-Lock and DoorSense, your home automatically secures once your door is closed, or after a set amount of time (optional feature).
  • EASY TO INSTALL ON ANY DOOR: Even if youre not so handy, installation only takes about 10 minutes. August locks fit perfectly on most single cylinder deadbolts.
  • RENTER-FRIENDLY: Renting your place? Home improvement isnt just for homeowners. Modernize your apartments lock and then take it with you when you move -- the old deadbolt thumbturn can be easily reinstalled.

    • Designed so people aren't confused on how to unlock it
Color: Silver
I finally upgraded from the original first gen round August Lock (which I've been happy with your several years now) to this third gen version. The biggest reason I wanted to upgrade was the fact that the design of this one is like a regular lock. While the round one was working just fine, unfortunately other people unfamiliar with the lock just became baffled on how to unlock the door from the inside. With the design of this one, that eliminates that confusion for guests and it looks like a normal door lock to them. The additional features I like compared to the first gen one was the addition of the door sense feature. I haven't experienced it enough yet to really comment on it, but the initial testing of it was nice to prevent it from trying to lock when the door was still open. The issue I did have on the first gen one was that it could sometimes jam the lock if it tried to lock when not fully latched or closed. This one so far also seems to be a lot better with the smart alert notifications. The first gen one was hit or miss when notifications would actually work with the wifi hub. But so far this new one seems to actually notify every time per my settings. The only negative thing I have about the third gen vs the first gen is the missing sounds. On the first gen one, you could have it make lock and unlock sounds when used by the app or auto lock/unlock. Unfortunately the 3rd gen doesn't have the sounds built in. It is louder when the device is working, which somewhat substitutes for that so you can hear it working, but I'd still rather have the lock and unlock sounds option. Outside of that flaw, it is still a great product. If you are a renter, it is also perfect as the original keyed entry doesn't change, and you still only swap the inside part, and when you move out, you simply put the original inside piece back. That's why I preferred August Lock from anything else. It is simple, yet effective. Now I have a spare first gen one, maybe I'll just use it for the back door. ... show more

    • Must own the Connect to enjoy its features, must be patient on setting up for best signal.
Color: Silver
Package includes the Lock itself , 3 retrofit attachment to match your current front key cylinder , and the DoorSense - it is just basically a strong magnet placed on the door jamb (screw-up or drilled inconspicuously a couple of inches below the bolt). The way it works is the August lock somehow detects if the magnet is at its strongest to tell the door is closed or otherwise ajar. The app has a calibration tool to tell the lock whether it is closed or ajar. I installed the Hardware and app with ease. My first intention to purchase this lock is to use its autolock feature, my door is equipped with deadbolt lock paired with a storeroom type of lock- it is always lock where you can exit with a twist but always needs a key to entry. However, I still feel not secure when household just closed the door on their way out. They just gets used to exit at night without locking the deadbolt part. At first I was so excited and felt so relieved to find this lock then I realized another problem arises. If I get used to this close-and-forget. I may not tell if still working like if it needs new battery without constantly dreading about it. Basically the lock communicates by Bluetooth which means is you have to be close to it like 10 ft. with your phone. Beyond it, you still have to either get closer everytime to check on the app or physically checking it which beats the purpose. So I bought the Connect, it links your lock to the internet thru your router. it's very tricky to install. It needs to have a good to excellent signal from your router and at the same time must also be close to the lock 10 to 15 ft away to link the Bluetooth signal. im thankful I have i have 3 routers, even though I have 3 choices i still got difficulty finding the best location. The best I have found is I put the Connect in a very short extension cord and plug it to the ceiling light bulb indoor above the door entrance. From there I have good signal from router and Bluetooth which is enough. I have both iPhone and android and I'm using auto unlock features so far with precision. I think Auto Unlock detects you away when you are out of your wifi signal and detects you home when your phone picks up your wifi signal. Everytime I am about 10ft walking towards the door, I think phone's Bluetooth links up the lock and I can hear my phone notifications, Auto unlock engages and I verified it. Love it, I am able to checks its status on my phone anytime. Anywhere. It also gives you alerts, if it's been manually locked or unlocked. Someone remotely locks or unlock it. If it's in ajar status or it uses its auto locked feature. It's not perfect but I'm satisfied. I wish it has its own notification sound selection than using the phones general notification setting. So there's a differentiation between the others. And I wish the app connects automatically to the internet if Bluetooth is out of range.- in the app you have to press a button to get the signal from the internet after it tries to connect to Bluetooth which is always out of range (needs user interaction, lacks smooth transition) ... show more
