The Best Smart Locks of 2019

By Nick Schmiedicker, December 26, 2018, Updated January 02, 2019

While no one's doubting the effectiveness of a standard door lock, there's a lot to be said for the latest smart locks. Popular manufacturers like Kwikset, Schlage, and Yale have already jumped on board to offer high-quality locks that come loaded with useful features, and now door locks can be counted amongst some of the best Alexa-compatible smart home devices on the market today. While we might (and should) be concerned about the hackability of this type of device, these companies know security. And you'd never know how useful virtual keys or auto-unlock can be until you've tried it. After months of testing and living with nine popular smart locks, I'd recommend the Schlage Sense (available at Amazon).

They all managed to pass the test of locking and unlocking my door, but there were clear distinctions when it came to the smart features, so much so that there are four things you should know before you buy a smart lock. It doesn't matter if you rent or own, use an Amazon Echo or Google Home, I've found the perfect smart lock for you.

These are the best smart locks we tested ranked, in order:

  1. Schlage Sense Smart Deadbolt
  2. August Smart Lock
  3. Kwikset Kevo Smart Lock 2nd Gen
  4. Kwikset Premis
  5. Kwikset Kevo Convert
  6. Schlage Connect
  7. Yale Assure Lock with Bluetooth
  8. Yale Touchscreen Deadbolt With Z-Wave

Schlage Sense Smart Deadbolt

Best Overall Best for Apple HomeKit

There's a lot to love about our top pick, the Schlage Sense. For starters, thanks to an interactive step-by-step guide in the app, it's incredibly easy to install and troubleshoot any issues that could come up. It's easy and intuitive to use, had the fastest average lock and unlock times (about two and a half seconds), and comes jam-packed with useful features.

Not only is it able to store and remember 30 unique passcodes, but it comes equipped with built-in alarm sensors that will issue an alert if it senses an attack. It's also Apple HomeKit compatible, which means you can ask Siri to lock/unlock your door and even through your remote control if you own an Apple TV as well. If you own an iPhone and have already taken steps to fill your home with Apple HomeKit compatible products, the Schlage Sense is a standout smart lock that should be on your radar.

As of November 2017, Schlage has added Android compatibility, so non-Apple users can now enjoy the best smart lock we've tested. And with the addition of the new Schlage Sense WiFi Adapter, Android and Apple users alike now have the ability to connect to and active the smart lock remotely. (We have not yet tested these new features, but will update you as soon as we do.)

August Smart Lock

The August Smart Lock blew our tests out of the water and is compatible with nearly every system out there.

August Smart Lock

Best for Alexa Best for Google Assistant

A very close runner-up to our best overall lock was the August Smart Lock. It's one of the most well known smart locks out there and has earned a well-deserved reputation for being a standout smart product.

It works with both Android/Google Assistant, iPhone/HomeKit, and Amazon Alexa. With it, you can use virtual keys to hand out temporary access, enable auto-lock and auto-unlock based on the proximity of your phone, and a history log of who comes and goes. But maybe most importantly, the August uses your existing deadbolt mechanism, meaning installation is a breeze and gives you that extra bit of peace of mind.

The only downside is that if you're interested in using the August with your Amazon Echo, you'll have to invest in the August Connect. With this bridge, you'll be able to move your August from Bluetooth over to WiFi, which gives you control over your lock via your phone no matter where you are. Alternatively, the Connect is what lets you use your Echo to control your lock via the August Home skill.

Editor's Note: There is a newer version of this lock, the 3rd-generation August Smart Lock Pro (check it out on Amazon). We haven't yet tested it, but will soon.

Can a Smart Lock Be Hacked?

Yes. Like any smart product, it's possible to hack into a smart lock. Cybersecurity should definitely be a consideration, but we should also consider the many ways a smart lock offers more security than a "dumb" one. While definitely possible, the odds of someone having the know-how and motivation to hack your smart lock are going to be much lower than the odds of a door accidentally left unlocked, a burglar finding a hide-a-key, or your key wearing out and leaving you in need of a locksmith. A smart lock prevents many unfortunate scenarios that can result from the vulnerabilities of a dumb lock. A smart lock can auto-lock your door, ensuring it isn't left unsecured. A smart lock totally eliminates the need for spare/hidden keys, and therefore lowers the likelihood one will be stolen/lost/copied. And depending on the smart lock you choose, your fingerprint or phone will be all you need to get in your house — no more fumbling for keys. So, while smart locks introduce some risks, they eliminate others. Just make sure the password to your smart lock isn't "password."

Kwikset Kevo Smart Lock 2nd Gen

Kwikset Kevo Smart Lock 2nd Gen

The Kwikset Kevo Touch-to-Open is another great lock that was impressively easy to setup and use. A step-by-step guide in the app provides easy and clear directions on installation, which should only take about 10 minutes if you have a screwdriver handy. After that, it's a simple matter of using your phone—or a tap from your finger—to lock and unlock your door.

That's right, I said tap from your finger. The Kevo Touch-to-Open, like its name implies, allows you to tap the exterior plate when your phone is within Bluetooth range to lock and unlock your door. In my testing, I found that it wasn't 100 percent reliable, sometimes lighting up with nothing happening. It consistently worked from the app, though, and had one of the faster lock/unlock times compared to the competition.

If you want the full and best possible experience, you'll have to pick up the Kevo Plus in-app upgrade. It'll set you back a few bucks, but will let you remotely lock your door no matter where you are and check the status of your door right from your app. It's not cheap, but you're getting a lot of convenience for it.

Kwikset Premis

Kwikset Premis

The Premis is the ideal Kwikset lock for anyone with an iPhone and an established HomeKit household. Through the iOS-only app, you'll be able to lock/unlock your door, check a history log of who's come and gone, send virtual keys, and even unlock your phone via Siri. The included touchscreen keypad lets you create up to 30 unique codes that could be permanent (for your family) or temporary (for visiting friends or Airbnb guests). Plus, if you own a 3rd generation or later Apple TV, you can control the Premis remotely.

It didn't have the fastest unlock/lock times, but it also never stretched past 5 seconds, which isn't something that can be said for all of the locks we tested. Still, if you're looking for a HomeKit compatible lock that performs exceptionally well, I'd recommend our number one pick, the Schlage Sense.

Kwikset Kevo Convert

Kwikset Kevo Convert

The Kwikset Kevo Convert is a simple way to keep your exterior lock and keys, and instead replace only the interior deadbolt mechanism. Much like the Kevo 2nd Gen, the Kwikset app will guide you through an interactive installation process that should leave you with a fully functioning lock in about 10-15 minutes. It's a bit more affordable than a full assembly smart lock, while keeping all of the same benefits.

The bad news is that in our testing, the Convert took upwards of 10 seconds to lock and unlock the door. That might not seem very long, but try saying that when it's 90 degrees outside and you're stuck waiting for your lock to let you inside.

Schlage Connect

Schlage Connect

Best for Smart Home Hubs

The Schlage Connect is a great app if you're smart home is already set up with a Z-Wave-compatible hub like the Wink Hub 2, which we used to test the lock. It has a touchscreen keypad for multiple, unique codes, improved security through built-in alarms and sensors, and can even work with your Amazon Echo—with the Wink skill activated.

Unfortunately, our tests found that working through two systems, in this case Wink and Alexa, will pretty severely delay any app commands and cause a higher chance of the app crashing, at least for Wink. The Connect was another lock that sometimes took up to 10 seconds to engage and lock/unlock my door.

Yale Assure Lock with Bluetooth

Yale Assure Lock with Bluetooth

I had a lot of high hopes for the Yale Assure Smart Lock, but unfortunately, it didn't meet my expectations. Not only was the installation a hassle, but the lock/unlock times weren't very good and it dropped the connection to my phone frequently. That combined with an unintuitive app resulted in a smart lock that just didn't stack up to the competition.

Editor's Note: There is a newer version of this lock available. The Yale Security Assure Lock is available on Amazon, and we will test it and update this article soon.

Yale Touchscreen Deadbolt With Z-Wave

Yale Touchscreen Deadbolt With Z-Wave

Likewise, the Yale Touchscreen Deadbolt with Z-Wave didn't perform to the expectations set by previous locks in this list. It suffered from the same headache-inducing installation as the Yale Assure but was saved by the same Wink app we used for the Schlage Connect. While the app was the exact same as the one we used with the Schlage, it frequently dropped our connection to the Yale lock.

Once everything was setup, it did unlock and lock the door in an average of five seconds—similar to most of the other locks we tested. Unfortunately, it's just not worth the hassle when there are other, better smart locks to choose from.
