Two of the best smart locks of 2020.

One huge advantage smart locks have over conventional deadbolts is that you never have to carry a physical key.

Instead, many smart locks have keypads for PINs and/or electronic keys, where the "key" lives in an app on your smartphone and communicates with your lock wirelessly. With both methods, you can create, revoke, delete, and limit them to certain time periods with a few swipes on your smartphone.

"Smart locks can add an invaluable level of peace of mind," says Misha Kollontai, CR's test engineer for door locks. "Depending on the model, you can view the status of your lock from anywhere and track who opens your door and when."

Below you’ll find the nine best smart locks from our tests, split into three categories and listed in alphabetical order. You'll find models from August, Eufy, Kwikset, Schlage, Yale, and Wyze.

Three of our picks are retrofit smart locks, which only replace the part of the lock that’s on the interior side of your door. Because the exterior part of your deadbolt will remain, you can still use your physical keys but also lock and unlock the door from your smartphone app. Another two picks are Bluetooth-only smart locks, meaning they don't offer a WiFi adapter (either in the box or sold separately), so you can't control and monitor the lock when you're away from home. The remaining picks are WiFi-capable smart locks, which connect directly to WiFi or through a WiFi adapter.

To evaluate both smart and conventional locks, CR engineers conduct kick-in tests using a custom-built jig that swings a 100-pound steel battering ram against a locked door. They repeat the test eight times, with the ram raised to ever-increasing heights, or until the lock fails. The models that fail—at least half do—go through another round, this time with a reinforced box strike plate (a basic DIY upgrade that improves security) installed on a new lock sample.

Best WiFi-Capable Smart Locks

Kwikset Halo 939WiFiTSCR

    CR's take: The Kwikset Halo is one of a growing number of WiFi smart locks on the market that don't require an additional hub or bridge to connect to the internet for remote control. In our tests, the Halo withstands kick-ins and lock picking well, but it's susceptible to attacks from a cordless drill. It receives strong scores for its convenience features, its ease of setup and connectivity to other smart home devices (such as smart speakers), and its ease of remote access, with an Excellent rating for the latter. Its feature set includes an access log to keep tabs on who comes and goes, an auto-lock feature, a touch-screen keypad for PINs, the ability to create PINs for family members and guests, and voice control via Amazon Alexa and Google Assistant.

     

    For the variant of this smart lock with a physical keypad instead of a touchscreen, see the Kwikset Halo 938WiFiKYPD.

    Kwikset Premis 919TRL 15 SMT

      CR's take: The Kwikset Premis is best for iPhone users because it works with Apple's HomeKit smart home ecosystem and Siri digital assistant. In our tests, the Premis receives an Excellent rating for its resistance to kick-ins as sold. Its physical design also makes it very resistant to lock picking, but it's susceptible to attack from a cordless drill. Still, this lock comes with some very helpful features, including an access log to keep track of who comes and goes, a tamper alarm, an auto-lock feature, and the ability to create and share PINs with others. Just note that because this lock uses Bluetooth and HomeKit, you'll also need an Apple TV, Apple HomePod, or Apple iPad (that's constantly plugged into an outlet) in your home to control the lock remotely.

      Schlage Encode WiFi BE489WB-CAM-619

        CR's take: The Schlage Encode was one of the first smart locks on the market that connects directly to WiFi, negating the need for an additional hub or bridge to connect it to the internet. While the Encode features a keypad for PINs, you can also create electronic keys for guests so they can lock and unlock it without a numeric code. In our tests, the Encode stands up very well to kick-ins as sold, but it's more susceptible to picking and drilling. It does receive an Excellent rating for its ease of remote access, though. Its many features include remote control via smartphone app, voice control via Amazon Alexa and Google Assistant, an access log, an auto-lock feature, a tamper alarm, and compatibility with Amazon Key in-home delivery service.

        Yale Assure YRD256-CBA-619

          CR's take: The Yale Assure Lock SL uses its sister company August's smart lock platform, complete with a smartphone app almost identical to August's that simply uses Yale branding instead. That means it offers many of the same features as the August smart locks below, including remote control, an access log, voice control (via Amazon Alexa, Apple HomeKit/Siri, and Google Assistant), electronic keys, and a door open/close sensor. This lock also comes with Yale's version of the August Connect WiFi adapter, $79, which is needed to use all those features, at no extra charge. In our tests, the Yale Assure Lock SL receives a Very Good rating for its resistance to drilling. It's also impossible to pick because it's keyless, and it's very resistant to kick-ins as sold.

          Best Bluetooth-Only Smart Locks

          Eufy Smart Lock Touch

            CR's take: The Eufy Smart Lock Touch can't connect to the internet for remote control, but it still packs plenty of features and performs very well in our tests. This lock offers a fingerprint scanner, a touch-screen keypad for PINs, an access log to track who comes and goes, an auto-lock feature, and the ability to lock and unlock it from its smartphone app via Bluetooth when nearby. In our lab tests, this Eufy rates Excellent for its resistance to kick-ins as sold. It's very resistant to picking, too, but could be better at withstanding drilling. This lock also scores highly for its convenience features and ease of setup.

            Kwikset Aura 942 BLE

              CR's take: The Kwikset Aura 942 BLE is a dependable Bluetooth-only smart lock, offering strong performance in our kick-in and lock picking tests. It receives a Very Good rating for its ease of setup and connectivity, but its feature set is limited compared with other smart locks, resulting in low scores for our ease of remote access, security add-ons, and convenience tests. It features a keypad for up to 250 shareable PINs, an auto-lock feature, and the ability to lock and unlock from its smartphone app via Bluetooth when nearby.

              Best Retrofit Smart Locks

              August Smart Lock Pro AUG-SL-CON

                CR's take: The retrofit August Smart Lock Pro offers a ton of smart features, including auto-locking and unlocking, voice control (via Amazon Alexa, Apple HomeKit/Siri, and Google Assistant), access logs, electronic keys, a door sensor (to tell if the door is closed, not just locked), and compatibility with Z-Wave Plus smart home hubs. The lock has remote access features, but you'll need to buy it with the August Connect WiFi adapter, $79, to get those features as well as voice control. It rates Excellent for convenience in our tests and is very easy to set up. If you'd like to use PINs with this lock, August sells a separate wireless keypad for $60.

                August WiFi Smart Lock AUG SL05-M01-G01

                  CR's take: The August WiFi Smart Lock is the successor to the August Smart Lock Pro above, offering a smaller physical design and connecting directly to WiFi without the August Connect WiFi adapter for $79. It receives identical scores in our performance tests—with a rating of Excellent for remote operation—and offers all of the same features (including those that required the WiFi adapter) except compatibility with Z-Wave smart home hubs. Its feature set includes auto-locking and unlocking, voice control (via Amazon Alexa, Apple HomeKit/Siri, and Google Assistant), access logs, electronic keys, and a door sensor. If you'd like to use PINs with this lock, August sells a separate wireless keypad for $60.

                  Wyze Lock WLCKG1

                    CR's take: The Wyze Lock is the first smart lock from this budget smart home company, and it performs quite well in our tests. It rates Very Good for remote operation and scores high in our convenience and security add-on evaluations. Its features include auto-locking and unlocking, an access log, electronic keys, an integrated door sensor, voice control via Amazon Alexa (Google Assistant integration is in the works), and an alarm to let you know if the door is left open after a set amount of time. If you'd like to use PINs with this lock, Wyze sells a separate wireless keypad for $20.
