The latest August Smart Lock is at its lowest price ever, $184

Securing your home is about the most important home improvement upgrade you can make, and with smart locks, it's never been easier. The latest version of August's Wi-Fi smart lock, the fourth generation, is a favorite here at CNET. The retrofit-style lock is easy to install, has Wi-Fi built in and works with all the major voice assistants. The fourth-gen model is priced at $230 on Amazon, Best Buy and other major retailers but right now you can get theAugust Wi-Fi Smart Lock (4th generation) for $184 at Wellbots when you apply promo code 15CNET to the already discounted price at checkout. That ties with the lowest price we've ever seen for this top-rated smart lock.

August has been making smart locks longer than almost anyone, and this model is an updated version of the popular lock that put the company on the map. The "retrofit" approach means that the lock doesn't replace your existing deadbolt, so you can still get in the house with your existing front door key if you want to, and the whole August smart lock installation takes about 10 minutes -- 15 if you're not handy with a screwdriver.

The new lock is about 45% smaller than the August Smart Lock Pro, but otherwise looks basically the same. And because it has integrated Wi-Fi, you don't need to buy the $80 Connect accessory or sacrifice a nearby electrical outlet to plug it in. It's completely self-contained. That said, this new version also makes the switch from AA batteries, which can last the better part of a year, to CR123 cells, which only last about half as long.
