August's fourth-gen smart lock is 31 percent off for October Prime Day

The huge October Prime Day sale isn’t done yet. There are deals aplenty to check out before the sale ends Wednesday night/Thursday morning, including a discount on August’s fourth-gen smart lock.

The black version of the device has dropped to $158 for Prime members, which is $72 off the regular price. The silver version is available for $160. This is not quite the lowest price we’ve seen for this model — it has dropped to $139 in the past — but this is still a solid discount.

This is one of our favorite smart locks. We gave it a score of 80 in our review. It's easy to install and the smart lock won't take up too much space, so it shouldn't look too clunky on your door — it's slimmer than prior iterations. You won't need a separate bridge device to use the Wi-Fi feature either, as it can directly connect to your network. On that note, August's fourth-gen smart lock is only compatible with 2.4GHz networks, so you may need to adjust your router settings to account for that.

The smart lock should work with most existing deadbolts, so you'll be able to use the same physical keys if need be. That's handy for when your Wi-Fi is on the fritz. Otherwise, you'll be able to lock and unlock your door remotely, including with the likes of Alexa and Google Assistant. You'll also have the ability to provide guests (such as kind friends who are checking on pets and plants while you're away) with timed-entry keys, which will allow them to enter without having to wait for you to unlock the door manually.
