Review: Remote access but difficult to install if not deadbolt initially
Review: 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.

## Questions & Answers

**Q: What is the difference between this and august smart lock pro?**
A: Aside from the way it looks, from my research the only difference is that the Smart Lock Pro has Apple Home support and this one doesn't. I don't use any apple products so I chose this model. It's been working great for me so far.

**Q: Does this require a hub**
A: It doesn't require a hub to unlock your door via Bluetooth on your cell phone.

With a "smart keypad" you can unlock your door with by inputting your code into the keypad programmable via your cell phone. 

With the hub you can unlock/lock, get remote notifications through wifi, and your cellular provider, retrieve records of activity remotely, connect with other services such as IFTTT and Airbnb

**Q: Do i need to buy a hub or will the echo plus with built in hub work? Im asking this question, because ones that are answered are with " i dont know"**
A: Not sure if you are asking about the August lock or Amazon Echo.  The lock uses Bluetooth to function with your phone in your home.  If you wish to access it from a location outside of Bluetooth range (which is measured in a few dozens of feet) you must purchase the WiFi extender from August.  And for that to work you must have WiFi in your home.  Hope this helps

**Q: Is there a way to unlock if my phone battery is flat or I forgot my phone?**
A: The easiest answer is to unlock it with the key you are using right now. If there is still battery, other options are the smartphone app, key code (with optional keypad). With wifi, Siri and Alexa, assuming the August Connect is also equipped.

### ⭐⭐⭐⭐⭐ Review
*by J***G on December 30, 2018*

This is a fantastic lock especially if you live in an apartment with strict strata laws. The lock looks normal on the outside because the smart lock is installed on the inside. Because of this, you can still use your regular keys to open the door, especially when/if the lock runs out of battery. Everything is installed and optimized through your smartphone and is unlocked/locked via Bluetooth connection. It comes with door sensors so it can automatically sense when your door is locked, meaning that you can walk away from your door without any worries. At most, it will take you roughly 15-20 minutes to install. Within the app, you can invite family and friends to have either guest or owner privileges to your lock which eliminates the need to cut keys for them. You can also track who opened your door and how (manually or wirelessly) and at what time. This lock gives you so much control for your home and it's the best investment that I've made in the past 5 years. They do need to make some improvements to the application itself since it can be quite slow in connectivity, but you can't really expect much from Bluetooth connections. Highly, highly recommended!
