Securing your home is obviously important, but it can also be a tedious process. Fumbling around for your keys while juggling groceries or other packages is not only inconvenient but might also result in accidents. And then there’s the worry that you or your family members and friends will lose their set of keys, jeopardizing the safety of your home. In addition, there may be people, like housekeepers, dog walkers, and the like, who need temporary access, but you don’t really want them walking around with the keys to your home.
A smart lock provides a variety of options for locking and unlocking your door, including voice activation, keypads with specific codes, and fingerprint access.
Here, the best smart locks to meet your particular needs.
Best Overall: August Wi-Fi Smart Lock
Dimensions: 2.8 x 2.75 x 2.8 inches | Smart Home Compatible: Yes | Locking Mechanism: App | Lock Type: Connects to an existing deadbolt
Compatible with your existing deadbolt and key lock
Setup might prove to be difficult
The August Wi-Fi-Smart Lock is convenient to use and easy to install. Because it works with your existing deadbolt and key lock, you won't have to buy a whole new system—and for added convenience, it's also compatible with most single-cylinder deadlocks. The auto-lock/unlock function can use your phone’s location to unlock the door when you’re close to it (helpful for when your hands are full), and re-lock the door after a specified amount of time has passed—or immediately after you close it.
In addition, you can choose to lock the door manually or control it with Siri, Alexa, or Google Assistant. For added security when operating the lock remotely, you have the option of adding your smartphone’s fingerprint or facial recognition features—and using the August app, you can issue secure virtual keys via your smartphone to friends, family members, and other people who need access, and then cancel access when it’s no longer needed. The lock doesn’t need an additional bridge to connect to Wi-FI.
The August Wi-Fi-Smart Lock also has a smart and attractive look, and it doesn’t take up a lot of real estate on your door. It’s available in either Silver or Matte Black, and there’s also an option to add a keypad.

Dimensions: 3.99 x 4.24 x 9.74 inches | Smart Home Compatible: No | Locking Mechanism: App or keypad | Lock Type: Deadbolt
Easy to install
No smart home integration
If you’re looking for a good smart lock that won’t break the bank, the Kwikset Aura offers a lot of features at a great price. Using the Kwikset App, you can use Bluetooth to operate it from your smartphone to both lock and unlock the deadbolt. There’s also an auto-lock feature to activate the lock 30 seconds after the door has been closed. The Kwikset allows you to program up to 250 different codes and even create a schedule to determine when those codes are enabled. In addition, the app provides notifications so you can see current lock activity.
Best Splurge: Nest x Yale Lock with Nest Connect

Compatible with Google Nest
It’s pricey, but the Nest x Yale Lock with Nest Connect is a good-looking lock that combines Nest technology with Yale durability using the Nest app. And if you already have a Nest Connect hub or Nest Secure security system, you’ll only need to purchase the lock, which would be approximately $150 less. It also works with Google Assistant. The lock is easy to install and features one-touch locking. You can also lock and unlock the door remotely using your phone and view the timeline showing who opened or closed the door—and when. In addition, temporary or permanent passcodes can be created for family members or friends.
Best for Apartments: Wyze Smart Door Lock
Dimensions: 2.5 x 2 x 4.9 inches | Smart Home Compatible: Yes | Locking Mechanism: App | Lock Type: Connects to an existing deadbolt
Easy to install
Doesn't work with smart home systems
Just because you don’t own your home doesn’t mean you can’t enjoy the convenience of a smart lock. The Wyze Smart Door Lock works with most single-cylinder deadbolt locks, so you won’t get in trouble for trying to change out the locks and keys. The auto-unlock function is enabled when you approach the door, and it will lock itself after you get into your home. In addition, the built-in gyroscope lets you know if the door is ajar. The Wyze app also lets you assign codes to friends and family members and lets you view who has locked or unlocked the door. The lock can also be used with Alexa.
Best Deadbolt: Schlage Encode Deadbolt Smart Lock
Dimensions: 3 x 0.89 x 5 inches | Smart Home Compatible: Yes | Locking Mechanism: App, keypad, or key | Lock Type: Deadbolt
Easy to install
Can be operated by a key
Compatible with Alexa and Google Assistant
Could use longer auto lock intervals
A sturdy deadbolt is essential if you have serious concerns that someone could break into your home. Schlage is known for its strong deadbolt locks, and the metal construction on this smart model is no exception. However, the Schlage Encode also includes an alarm to alert you (and is probably loud enough to alert the neighbors) if someone tries to breach the lock. It’s easy to install and can be operated by a key, touchscreen number pad, and remotely from your smartphone. The smart lock also works with Alexa and Google Assistant. It generates up to 100 codes and has an activity log. You can also use the Amazon Key App to allow delivery drivers to access your home if you don’t want your packages to be left outside.

There’s also a 360-degree live fingerprint ID feature, which works from any angle. In addition, there’s a manual key option, auto-lock, and remote smartphone access. The Ultraloq app lets you manage other users and view the activity log.
This lock is easy to install and rated dust and weatherproof. While it does require an extra WiFi Bridge to use certain features (including the remote-control function), the company also makes a latch version that includes the WiFi Bridge.

It’s easy to use and install, and it works with your existing deadbolt and your existing Wi-Fi, so you don’t need to make any additional purchases.

It also includes several ways to access the lock, in addition to the Amazon Key App for delivery drivers.
What to Look for in a Smart Lock
Most smart locks are easy to install and usually require only a screwdriver. Some smart locks work with your existing deadbolt, while others include a deadbolt and new keys. If you’re renting, you might have to rule out a model that doesn't work with your existing deadbolt.
If your door is exposed to the elements, you’ll want a smart door lock that is waterproof and can handle temperature extremes. Certain types of smart locks are notorious for being unreliable when the temperature dips too low, so this is important to keep in mind. Also, if there are going to be a lot of people accessing the lock, make sure that it's durable enough to withstand frequent traffic.
How you plan to use the smart lock can also determine the best one for your purpose. For example, a fingerprint feature is ultra-cool, but if you have small kids and older parents, will they be able to provide a sufficient biometric fingerprint?
For keypads, some people may struggle to key within the lines, which could result in them pressing “2” when they’re trying to press “3.” If that's the case, you may want to opt for a keypad that spaces out the numbers.
If you prefer to unlock the door for kids, family members, etc., remotely, make sure you’ll be in a location with a strong enough signal. And if you plan to unlock the door at certain times, for example, 3 p.m. each weekday when your kids get home from school, one concern with creating a consistent routine is that it may catch the attention of would-be criminals.
Another consideration is how the smart lock integrates with your smart-home platforms, including Google Nest and Amazon Alexa. This might allow you to operate the lock with your voice, or get notifications from your smart home systems about any doorstep activity.
What is a smart lock?
A smart lock is connected wirelessly to your network, allowing you to leave your keys behind and operate it with a touch of a finger or a simple voice command. Besides convenience, they also add a layer of security, allowing you to monitor the comings and goings at your home. There are more advanced features like app access, entry codes, access limitations, and more. The technology for smart locks is always changing, and more features are being added regularly.
How do you use a smart lock?
How you use a smart lock depends on what type of lock it is and how it was set up. To use the lock at the door, you'll operate it by a keypad, fingerprint reader, or voice command. After the lock has accepted your access, you can lock and unlock it. You can also use a smart lock with an app that acts as a remote control for the smart lock.
How do you install a smart lock?
The best way to install a smart lock is by following the manufacturer's instructions for your particular lock. This will tell you exactly what you need to do and will provide diagrams to help you get everything set up. Installing a smart lock is similar to installing a standard lock with a few extra components. Generally, you'll first install your new bolt into the door frame, securing it with screws. Next, you'll take the outdoor portion of the lock and insert it into your door, threading the wiring beneath the bolt hardware. You'll then attach the interior assembly and connect the wires. Put the interior lock on the door and secure it. Now you're ready to install your batteries and use your new smart lock.
How do smart locks work?
Smart locks work by being connected to Wi-Fi or Bluetooth. They use fingerprint scanning technology, voice recognition, or keypad entry. People who are allowed to use the lock have their information stored so they can later access it. Smart locks all work a little differently depending on the features included.
