Best smart lock for a keyless home  12/05/2019 11:00:00  6  Christopher Null

While traditional lock-and-key systems have improved over time, the basic mechanism hasnt really changed since the first lock was invented more than a thousand years ago: A piece of metal that is just the right shape pushes pins inside a lock into the proper position, allowing the lock mechanism to turn. As a society, its been tough to replace a system that has worked reasonably reliably for literally a millennium.

Are smart locks really better?

You can thank the hospitality industry for finally pushing locks into the digital age. Hotels learned long ago that keys are easily lost, expensive to replace, and simple to bypass, as thieves can pick locks or simply make copies of a key to allow for unfettered future access. On the flipside, hotel guests have readily accepted key cards (and in some cases, smartphone-based solutions) as the primary means of getting into their room. The electronic solution is just so much simpler. Lost hotel key card? Replacing it is no big deal.

But the biggest benefit of electronic entry systems is that they are highly configurable. Digital locks can be changed at a moments notice (which is why that old hotel key card in your wallet isnt good for anything), and the property owner can generate a record of when each door was opened. In a more advanced setting, different keys can be generated for the same lock, so a homeowner can tell when each member of the family came in, or when the housekeeper arrived. Whether you have a teenager that tends to break curfew or merely want to give temporary access to houseguests, service providers, or Airbnbers, smart locks are an incredible upgrade over the old way of doing things.Ready to make the jump to smart lock technology? Here are our top picks of the market at the moment. Well be adding more reviews to this story as time goes by.

Updated December 5, 2019to add our review of the Yale Assure Lever with Connected by August. Either product alone is fine and dandy; the combination is anything but.

Best smart lock overall

The Schlage Sense smart lock may not win any awards for attractivenessor ease of installation, given the two dense instruction manuals that must be followedbut if you really want to secure your home with a smart lock, and have faith that its actually working, this is the product to get.

What if youve lost your phone? You can open the lock via an illuminated, smudgeproof numeric keypad or with a physical key. A recent update added the ability to unlock the door with a voice command (youll need to speak a PIN code you set up to complete the action).Schlage added the same feature to the similar Schlage Connect.


A close runner-up to the Schlage Sense is the very similar Kwikset Premis, which also offers a touchscreen keypad, keyed entry, and HomeKit compatibility. Even without an Apple TV, you can use Siri to tell the Premis to open and close; this all gets set up during the initial installation. The app is simple and streamlined, though that comes at the expense of more advanced features, like geofencing and the ability to set individual access schedules. The Premis feels a touch less sturdy than the beefy Schlage, but if a less obtrusive (and a bit more simplistic) lock is more to your style, its a no-brainer.

Best retrofit smart lock

Our clear favorite for retrofitting an existing deadbolt with a smart lock is the brand-new August Smart Lock Pro. Like the original August Smart Lock, the Pro is a classy, post-modern piece of hardwarethe Nest of the smart lock spacethat doesnt just look impressive on your door, it actually does an awful lot, too. (Nest has since partnered with Yale to produce the Nest x Yale Lock.)

The streamlined installation process is one of the easiest in this group, and unlike our runner-up, once youre finished it becomes a real part of your smart home, integrating with Alexa, Apple HomeKit, Google Assistant, the Wink Hub and Samsungs SmartThings. Whats more, the August Connect Wi-Fi Bridge is now included in the price of the lock, and another new featureDoorSenseinforms you when your door is ajar.


Just pop off your old deadbolt and affix the Kevo Convert in its place, and voila! Your smart homes lock is upgraded. The Kevo Convert isnt as easy to install as the August Smart Lock, but it does offer some upgrades in the form of a more familiar interior deadbolt design and plenty of app-driven features, such as keys that expire after a preset time.

Unfortunately, the Kevo Convert is a Bluetooth-only affair, so it cant be hooked into a smart home networkthough a $100 add-on called Kevo Plus can at least let you check your locks status and open it when youre not at home. On the whole, if your needs are simpler (and your existing lock is compatible), the Kevo Convert is a reasonable way to get started with smart lock tech.

What to consider when shopping

How do you pick a smart lock? (No pun intended.) This is a young and wildly immature space, and many products on the market are still extremely rough around the edges. Even top products can balk when dealing with old or stiff deadbolts, doors that dont shut well, or environments where non-standard fixtures are in use. The bottom line is that its tough to declare that any product is universally perfect for every home. That said, here are some key considerations to take into account to help you narrow down your shopping list.

How smart is it? An important caveat to consider first: Some smart locks dont work with a smartphone app or any smart home networking hubs at all; theyre really just electronic locks that use a code instead of a key to open up. One step up from that, youll find Bluetooth-only locks. These work with a smartphone app, but cant be monitored remotely or via a smart home system. Thats fine if youre looking to get rid of the keys in your pocket, but less impressive if you want to make your entrance portals a true part of your home network.

Replace or retrofit? Youre forgiven if you dont want to replace your antique doorknob on your vintage Victorian with a metallic device that looks like it would be more at home keeping people out of a strip mall bank branch. A sizeable number of smart lock products dont require you to replace all your existing hardware. Instead, they are installed on the inside of the door only, replacing only the interior part of the deadbolt. You can continue to use a standard key from the outside or open the lock via a smartphone app.

Smart home hub integration If you have an existing hub like the Wink Hub 2, Samsung SmartThings, or an Apple TV, youll want to ensure your chosen smart lock is compatible from the start. Many smart locks support Bluetooth, so they work with your phone, but lack the technology needed to connect with your home network. Some Bluetooth locks, like the Yale Assure system and the August Smart Lock, offer a radio module as an add-on to connect to your home network. If youre using a smart home hub like the Samsung SmartThings or Wink Hub, look for a lock that supports Z-Wave or ZigBee, instead.

Alternate entry means Forgot your phone at the office? How will you get in the house? Physical key? Numeric keypad? Wait for your spouse to arrive? Myriad different approaches are available.

Power backup What do you do if the batteries inside the lock dieand youre stuck outside? Some locks allow for emergency power to be applied should this happen. Yales Real Living locks feature external posts to which you can connect a 9-volt battery, giving you enough juice to get the door open. Other models retain the traditional key cylinder for backup.

Geofencing Bad about manually locking the door when you leave? A geofencing system automatically locks the door when it detects your phone has left the vicinity, and can be set to automatically open up when it finds youve come home.

Guest access features Most smart locks let you set up temporary keys for houseguests, which you can delete when theyve returned home. Smarter systems even let you set time restrictions around when each access code can be used.
