August

August Smart Lock

The August smart lock's appearance is immediately striking and will give any door a futuristic look — with your choice of dark gray or silver finishes. You can use your smartphone to remotely unlock or lock your door, or you can set up a proximity lock: Your door will unlock when you get approach with your phone and lock when you move away.

August's smart lock is listed among the Wirecutter's choices for best smart lock, especially for those who prefer to keep their existing hardware (I'm looking at you, renters!).

August lets you create virtual keys for friends and family staying at your place, and keep tabs on the comings and goings of your household using a built-in 24/7 activity log. The August smart lock requires no wiring and installs using an existing deadbolt. It's also HomeKit-enabled, so you can use Siri and the new Home app to control your locks.

Consider the August if you'd like a smart lock that keeps track of activity and is fully compatible your iPhone and iPad. You can grab the August Smart Lock for about $200 on Amazon.

Kwikset Premis

Kwikset Premis Smart Lock

The Kwikset Premis smart lock features a capacitive touchscreen keypad in an all-metal enclosure. It comes in two finishes: Satin Nickel and Venetian Bronze.

You can lock and unlock your door using the keypad, the Kwikset app, or — thanks to HomeKit compatibility — Siri. The Premis offers up ongoing lock status information, so you can see who locked and unlocked your door and when they did it. It also features some handy security improvements, like an alarm that sounds after three incorrect code entries and SecureScreen, which requires you to touch two random numbers before entering your code (so no one can use your fingerprints to guess your entry code).

The Kwikset Premis is a great smart lock for anyone who wants a well-designed lock from a trusted company, but you'll need to be comfortable with replacing your door hardware. The Kwikset Premis is available on Amazon for about $230.

Kwikset Kevo Smart Lock

Kwikset Kevo Smart Lock

Given that this smart lock consistently receives a Wirecutter recommendation and it's also a popular, best-selling product, we have no problem giving Kwikset's Kevo smart lock a place on our list.

The Kevo comes in two styles: a full replacement for your existing deadbolt or an August-Smart-Lock-style conversion kit that fits into your existing deadbolt.

Kevo offers a keyless, touch-to-open feature by using Bluetooth technology to recognize your smartphone and authenticate your identity. You needn't go searching for your keys — just touch the deadbolt and unlock!

To keep track of your Kevo lock outside of the home, you can purchase the Kevo Plus — a WiFi connected device that gives you remote access to your smart lock.

Kevo is a great option for just about anyone looking to upgrade their dumb deadbolt — so long as you're not interested in HomeKit compatibility. Amazon lists the Kevo Smart Lock for about $200.
