Nowadays it feels like it's in our homes, from our kettles to our TV's, but it's smart technology.
Smart locks have come a long way in both technology and design.
From August to Kwikset to Yale, there are a wide variety of smart lock input methods and designs, from touchscreens that do not know are smart locks from the outside. The key is to find which smart lock works well for you, your door, and your home.
We are using this guide for the best smart locks on the market and unlike these products.
Nest x Yale smart lock
An excellent smart lock … if you own other Nest products
Dimensions: Exterior: 2.59 "x 4.59" x 0.08 " / Interior: 2.78 "x 7.03" x 2.02 "| Weight: 2.42lb | Power: 4 AA batteries (included)
The Nest x Yale lock integrates with your nest of smart home products, so this device extends well beyond your front door. It's an all-round excellent smart lock, though it's probably out of the way in other nest devices.
Setup is often a sticking point when it comes to smart locks, but the nest x Yale lock is easy to install and connect to your internet (if you spring for Nest Connect, that is). The lock features a keypad on the outside, so you punch in a code to enter your house, rather than insert a key.
One neat feature is one-touch locking, which allows you to lock your door just by pressing the Yale logo. To unlock with the same method, you press the logo again, then follow a few steps before your door is opened to you. There's also the option to have the nest x Yale lock at a pre-set time, especially helpful if you forget to lock your door at night.
The Next x Yale lock is also available in Satin Nickel, Oil Rubbed Bronze and Polished Brass, so no matter what your style is, you should find that that fits.

Skept Smart Lock
A solid smart lock that's on the bulky side
Dimensions: Exterior: 3 "x 5" x 1
Easy to install
The Schalge Sense is another easy to install and use smart lock, though its size runs a bit on the bulky side.
You can lock and unlock your door straight from the app or by entering codes on the keypad.
Using the app, you can create and delete codes, convenient if you want to create codes for house guests. However, to use this feature, you will need to do so over Wi-Fi or via the lock's built-in Bluetooth. In our own testing, we use the app to lock our front door at night, after we've gotten into bed and under the covers.
The app leaves something to be desired, and you need it.
The Kick Sense works with Apple's HomeKit, so you can use your Apple app on Apple TV, iPad or HomePod through the HomeKit app.
The lock also supports Google Assistant and Amazon Alexa, allowing you to use
August Smart Lock Pro
Wi-Fi Fi connected smarts in a discrete package
Dimensions: 3.4 "x 3.4" | Weight: 0.8lb | Power: 4 AA batteries (included)
Sold with Wi-Fi bridge
The August Smart Lock Pro is one of the best looking smart locks on the market market, though from the outside, you would never know it's there.
That's because your deadbolt looks exactly the same on the outside (in fact, it's the same one you've had), while the August Smart Lock Pro sits on the inside.
Using the August app, you can see if your door is closed and locked. Once again, the device will automatically unlock when you're 20-30 feet from your door, granting you easy, keyless access.
Conversely, the lock will automatically bolt into place if you leave the house in a rush, and you can check that your door is secure using your smartphone.
You can also send keyless codes to visitors or anyone who is dropping by your home on a regular basis, and track who's coming in and out of your door. Finally, you can control the August Smart Lock Pro with the voice assistant of your choice: Siri, Alexa or Google Assistant.
The Smart Lock Pro is ready to be unlocked and will be ready to go.
