Our favorite smart lock overall has been marked down by 35%; we love its ease of installation as it converts the interior half of your deadbolt without replacing your exterior lock. It automatically locks and unlocks your door and works seamlessly with every major smart home system. Best of all, you can still use your original door keys.

August streamlines the installation process by slipping over the interior portion of your lock. It's simple and works with your existing deadbolt and key. From the August app, you can control the lock, share temporary (or permanent) digital keys, and track activity. Its built-in sensors send you a notification if the door is left ajar and automatically lock the door once it's properly closed. 

The lock itself doesn't require a hub, and it integrates seamlessly with the biggest smart home platforms including; Amazon Alexa, Google Assistant, Apple HomeKit, and Samsung SmartThings. One of its standout convenience features though is the ability to use your Apple Watch to open your door with a tap. Overall, this smart lock is a solid pick for not only homes but also rentals since you don't have to replace your existing hardware. If you've ever worried about whether you locked your door while away from home or often need to leave a key under the mat for visitors, then this investment is a no-brainer.
