Best Smart Lock Reviews

August Smart Lock Pro Review

  • Auto-lock function

  • Siri, Alexa, and Google Assistant support

  • Z-Wave Plus technology

  • Two-layer encryption

  • Expensive

  • Works only with single-cylinder bolts


Thanks to several interesting and useful features, August Smart Lock Pro is one of our top choices.

With the patented DoorSense feature, you can always check if your door is securely closed and locked. Just open the app or use voice-controlled assistants to check the status of your lock wherever you are. If you’re not the type to worry about such things, you can use the auto-lock function on these smart door locks to save both time and your nerves.

The smart lock gives you automatic access when it senses you’re in the vicinity, but it also lets you invite guests into your home when you’re not by giving them time-sensitive digital keys.

When it comes to security, August Smart Lock Pro uses two-factor authentication, which is expected from the best smart door lock companies. It also protects your information with two layers of encryption, including Bluetooth energy encryption.

If you happen to lose your phone, you can easily disable the system by visiting the company’s website at any time.

Compatibility & Use

Since the smart lock attaches to your existing deadbolt, the whole installation process is fast and straightforward. The design allows you to use your physical key as usual, giving your family members a chance to adapt to the new technology.

That said, the August Smart Lock Pro + Connect system works only with single-cylinder bolts, so if you have a different type of lock, you’re out of luck. While you can control the lock with your app, the device is also compatible with HomeKit and most of the major virtual assistants today, including Siri, Alexa, and Google Assistant.

This means you can check the status of your lock anytime using your voice. The lock can also communicate with other smart devices in your home using the latest Z-Wave Plus technology.


The August Smart Lock Pro costs $159.99, but it comes with a complimentary Wi-Fi bridge if you want a Wi-Fi door lock. The full package also comes with the DoorSense sensor, lock adapter, mounting hardware, and four AA batteries.

If you choose to buy it without the August Connect Wi-Fi bridge, you’ll save $50. This is an important piece of equipment, so we recommend you opt for the package deal. You can pay for the system using PayPal or Amazon Pay.

Schlage Sense Smart Lock Review

  • Built-in tamper alarm

  • Custom access codes

  • Auto-lock feature

  • Compatible with Alexa and Google Assistant

  • Quite expensive

  • Requires a smart home hub


The Schlage Sense smart lock comes in two styles: Century and Camelot. The main difference here is the price, so if you feel that Century works better for your home, you will have to pay around $10 more. The lock comes with a built-in tamper alarm for additional security you didn’t even know you needed.

With these Schlage door locks, you can create custom access codes for your guests and schedule their arrivals. That way, you can authorize your handyman to come at a specific time of the day and receive a notification when that happens.

If you want the auto-lock feature, you will need to get the optional Wi-Fi adapter as well. The auto-lock feature is pretty useful because it secures your home as soon as you leave it, which is one of the major advantages of electronic door locks. You can even set the custom duration according to your preferences.

Compatibility & Use

This smart lock is compatible with the two biggest virtual assistants on the market: Alexa and Google Assistant. Needless to say, the Sense model also works with other Schlage devices to help you create a well-functioning modern smart home.

Besides using your voice, you can also control these best smart door locks with the Schlage Home app. It lets you keep track of several locks across numerous locations. Having fully customizable push notifications means you can choose only the alerts that interest you.

The smart lock will notify you when a member of your household uses the key, or your door remains unlocked for some reason.


Prices for the Schlage Sense high-security front door locks (without the optional Wi-Fi adapter) start from $172 and $181 on Amazon. You can choose between two designs and, as far as functionality goes, they’re exactly the same.

The Schlage Sense Wi-Fi adapter will cost you about $59.99 more, while the set of door handles will set you back another $80 and $93. When you add it all up, you’ll realize that this is one of the pricier devices on the market.

Nest x Yale Lock Review

  • Easy to install

  • One-touch locking feature

  • Unique passcodes

  • Access history

  • Does not support Amazon Alexa or Apple HomeKit

  • Steep price


Besides looking very modern and sleek, the Nest x Yale smart lock is also quite easy to install. With a regular screwdriver, you’ll be able to replace your old deadbolt lock within minutes.

It also has an auto-relock feature, which is common for smart locks nowadays. The system detects when you’re away from home and automatically locks the door. On the other hand, if you want to do it yourself, you can just tap the keypad at any time, thanks to the one-touch locking feature.

Another feature that makes it the best keyless door lock is that it lets you create unique passcodes for your guests or family members. They can only use them for a specific period, so it’s a great way to let a mail carrier in for an expected delivery or check if your kids came home safely after school.

Compatibility & Use

In keeping with Nest’s integration philosophy, this lock also works with other devices from the Nest Secure alarm system. If you’re a fan of this brand, you’ll have no problem creating a reliable, integrated security system in your home.

However, when it comes to compatibility with virtual assistants, this Nest product has one major downfall. While it can be connected with Google Home smart speakers, it offers zero support for Amazon Alexa and Apple HomeKit.

Given that the Nest door lock is a Google-owned brand, that’s not surprising, but it’s still annoying. The mobile app gives you all the control you need over the device, with customizable alerts and a rather useful access history feature.

You get a list of door-related events that have happened throughout the day. If you set your alerts, you will be notified when, for example, a specific person opens your Nest smart lock. This is not useful just for security purposes; knowing who is in your house at any given moment makes organizing daily events a lot easier.


The price of the lock starts at around $236.97, which is on the expensive side. Besides Nest Connect, the package also includes an installation guide, mounting screws, and four AA batteries.

Even though you won’t find much lower prices on Amazon, you might stumble upon some great bundle deals to help you equip your entire home with the best keyless door locks.

Lockly Secure Plus Review

  • Pin Genie feature

  • 3D fingerprint scanner

  • Offline access codes generator

  • Expensive

  • No Wi-Fi connectivity

  • No Alexa, Google Assistant, or Siri support


If you’re searching for an added layer of security to boost your smart lock system, Lockly Secure Plus might be the right choice for you. One of the most interesting features you’ll see with this Bluetooth door lock is the patented Pin Genie system that randomizes the numbers’ position on the keypad and makes it much more difficult for anyone to see your entry code.

Admittedly, it makes things a bit more difficult for you on a daily basis, but that’s the price of extra security. In addition to that, these front door locks contain a 3D fingerprint sensor that can recognize several fingerprint scan door lock profiles.

Since it’s 3D technology, you get maximum protection so that someone can’t use your lifted prints to get inside. If you want to stay home alone, you can turn on the at-home privacy mode and disable keypad access for a certain period.

An interesting feature that makes the Lockly Secure Plus one of the best door locks for rental property owners is the option of creating offline access codes. You don’t need an internet connection to generate a code.

Furthermore, your guests don’t need to install the Lockly app. Just create an offline code and give it to them in person or via a regular message. The device can store up to eight different access codes.

Compatibility & Use

The Lockly Secure Plus system is available as a deadbolt or a latch smart lock — the latter costs about $30 more. This is one of the best external door locks made out of high-quality, extremely durable material that can withstand both harsh weather and malicious attacks.

One of the Lockly Secure Plus’s main flaws is that it lacks Wi-Fi connectivity and can’t connect to the internet. Because of this, you can’t remotely lock or unlock your door, like you can with some other high-end products.

That said, if you really want this feature, you can simply choose a different Lockly product, namely the Lockly Secure Pro, which is slightly more expensive.

The Lockly app gives you the option to set real-time alerts that will notify you when someone enters your door. Besides that, you get a full log of daily events to make sure you don’t miss anything important.


The deadbolt version of Lockly Secure Plus costs $329.99, while the latch goes for the same price – $329.99. This is pretty much everything you get in the box aside from manuals and some extra batteries, which is pretty standard for keyless door locks.

RemoteLock OpenEdge RG Review

  • Excellent data protection

  • Lockout option

  • Supports Airbnb

  • Text and email alerts

  • No Alexa or Google Home support

  • No IFTTT support

  • Expensive


It might not be the best on our list, but the OpenEdge RG has a simple, sturdy design and can survive even the harshest weather conditions. What makes it one of the best door locks for salt air environments is that you can pay extra for an additional weather cover, especially if you live in a particularly rainy or snowy part of the country.

When it comes to security, OpenEdge certainly has some useful features. While the auto-lock option and temporary codes for guests are expected, RemoteLock goes beyond that. If there’s a power outage or loss of connection, the lock itself saves your data so as not to lock you out.

You can even turn on the lockout option after five incorrect access attempts to make sure no one gets lucky enough to beat the system.

Compatibility & Use

You can control RemoteLock’s best Wi-Fi door lock system either through your dedicated app or by visiting the website. The software allows you to create up to 40 custom-made weekly access schedules, which is plenty for any household.

Unlike most devices on the market, OpenEdge can also send you alerts via text or email, so you don’t have to rely solely on info from your mobile app.

The downside is that there’s no explicit support for voice-controlled assistants like Alexa or Google Assistant. If you were hoping to automate everything with the IFTTT service, that’s also not possible. RemoteLock provides support for vacation rental platforms like Airbnb and HomeAway, making it possibly the best smart lock for Airbnb properties.


The OpenEdge RG lock costs $236.99 without the weather cover, which costs an additional $35. The box includes the lock, deadbolt latch, strike plate, mounting plate, hardware, and two physical override keys. The bonus equipment abundance justifies the product’s fairly high price.

Ultraloq Gate Smart Lock Review

  • Built-in camera

  • Two-way audio

  • Wi-Fi connectivity

  • Events log

  • Some features locked behind subscription paywall

  • No Alexa, Google Assistant, or Siri support


The biggest feature of the Gate Smart Lock system is its built-in camera. It may not be the best home security camera on the market, but you get real-time video streaming and two-way audio communication with your visitors. The call button on the lock directly calls your phone number, meaning everything can be done remotely.

You can see who is at the door and let them in with a single press of a button. There is also the option of scheduling guests’ arrivals with temporary e-keys. These features contribute to users who consider it one of the most secure door locks on the market.

Additionally, thanks to its custom PIN codes, it can keep track of people coming in and going out, with a short recorded video of every guest. You will know exactly who came by and when. Basically, it is a full surveillance and security system.

Compatibility & Use

The installation process takes only a few minutes and is truly beginner-friendly. There is no wiring involved — all you need is a screwdriver included in the box. Of course, like many other smart door knob locks, this one also has a physical key backup in case anything goes wrong.

The lock can connect to the internet and allow you remote control wherever you are. However, there’s no support for virtual assistants like Amazon Alexa, Google Assistant, and Siri. This is surprising, as most smart locks on the market provide it.


Before we get to the price of probably the best smart lock in 2020, you have to keep its features in mind. The Gate Smart lock significantly surpasses its competition by being a hybrid security camera and door-locking mechanism. You get two devices for a slightly higher price of one, which is not a bad deal at all.

The cheapest option costs $99 and comes with a basic, free service subscription. The box contains the smart lock with a camera, battery, screwdriver, USB cable, eight door spacers, and three keys. The problem is that the free subscription plan has quite a lot of limitations. There is no scheduling option, video history, or video sharing.

For an additional $79.99 per year, you will get the Premium Plus service, along with all its benefits. It’s expensive, so you can simply skip this offer if you don’t need it.

Kevo Touch-to-Open Smart Lock 2nd Generation Review

  • Cheap than the competition

  • Everyday and scheduled e-keys

  • Simple touch-to-open mechanism

  • 2FA and lost-phone feature

  • Requires hub for Alexa support

  • Doesn’t support Siri or Google Assistant


Thanks to its positioning technology, this Kevo smart lock always knows when you’re home and when you’re away. As the name suggests, all you need to do to unlock the door is touch the lock, and it will instantly recognize you.

In addition to that, you also get the auto-lock feature that automatically turns the key when you leave your house.

Kevo’s heavy duty front door locks use military-level encryption that ensures your data can’t be hacked or misused in any way. Access to your device is secured with two-factor authentication, which is standard among all the major brands.

If you happen to lose your phone, you can easily disable all admin privileges online, so your security doesn’t get compromised.

Compatibility & Use

When it comes to popular voice-controlled services, this smart lock supports only Amazon Alexa. However, like most smart entry door locks, it is compatible with IFTTT and cooperates with several devices by other brands, including Honeywell thermostats, Ring Video doorbells, and Wear OS.

With the Kevo app, you’ll be able to keep track of all the people coming in and out of your home. You can also easily assign various types of e-keys to your friends, family, or one-off guests.

The everyday e-keys give people full access to your home, guest keys offer 24-hour access (which is perfect for rentals), while the scheduled e-keys work only at a specific time of the day. For example, you can schedule your contractors’ arrival and give them access for a limited period.


The traditional Kwikset Kevo smart lock costs about $152.11 on Amazon, but that price doesn’t include the hub you need to connect the device with Alexa. The connected hub costs an additional $95.

Yale Real Living Assure Lock SL Review

  • One-tap locking system

  • Backup battery power

  • Simple BILT setup instructions

  • Doesn’t integrate with Siri

  • No automatic unlocking


Yale has been in the lock-making business since the mid-19th century, so it’s safe to assume that this company knows what it’s doing. The Real Living Assure door lock uses a modern keypad as the main access point, allowing you to enter passcodes from four to eight digits.

The door can be automatically locked with a single tap on the keypad, or you can turn on the auto-lock option. In case the batteries die, the device also has a backup power system, which is why many users consider this to be the best keypad door lock.

With the Assure smart lock, you can create up to 25 custom user codes and give them to your friends and family. Don’t be afraid of making a mistake and entrusting codes to the wrong people; they can all be deleted anytime. If you choose to buy the optional Yale smart module, you can get up to 250 custom codes, which is too much for households.

Compatibility & Use

Replacing your old lock with this Yale smart lock is fairly simple and requires only a screwdriver. To make things easier, you get the comprehensive BILT instructions that will help you set everything up with 3D schematics and a step-by-step guide.

This door lock is compatible with two of the most popular voice-controlled assistants: Alexa and Google Assistant. Unfortunately, it doesn’t support Siri.


Prices for the Real Living Assure lock start at around $190.42. These Yale door locks have an optional Z-Wave Plus technology module that unlocks the remote control and increases the number of entry codes you can create to 250, which will set you back another $50.

These prices begin to stack up, considering that you also need a controller to make this all work.

iTouchless Bio-Matic Fingerprint Door Lock Review

  • Stores up to 150 different fingerprints

  • Live Layer optical sensor

  • Low battery alert

  • No Alexa or Siri support

  • Expensive


With the iTouchless door lock, you can choose how you want to protect your home — by using passcodes or fingerprints. The device can store up to 150 different fingerprints and 78 unique passcodes. It uses the patented Live Layer optical sensor technology to ensure maximum security and accuracy when reading fingerprints.

The lock has an integrated alarm system that keeps track of the battery life and lets you know when the levels are too low. As is the case with the best door locks on the market, this one has an auto-lock function that automatically locks the door three seconds after leaving your home.

Compatibility & Use

This smart door lock has a sleek and elegant design with a weather-proof casing that protects the fingerprint scanner and the pin pad, making it one of the best exterior door knobs.

To use the lock, you need to lift up the cover and expose the interface. You can easily install the door lock with the provided instructions. There’s no need to pay a professional to do it for you.

Because there’s no app for remote use of the lock, there is no compatibility with voice-controlled services like Alexa or Siri, unlike the other best smart lock brands we’ve listed so far. All the programming is done directly at the lock, where you can add or delete users through the pin pad. The lock is powered by four AA batteries that are usually not included.


iTouchless is justified in setting fairly high prices, considering that users view it as one of the best front door locks. However, this system really is on the expensive side; on the company’s website, it’s priced at $200.00. You can find much better deals on websites like Amazon and save up to $100.

Ultraloq UL3 BT Review

  • Waterproof and dustproof

  • High-quality OLED display

  • Anti-peep mechanism

  • Expensive


This smart lock lets you choose between two authentication methods: a fingerprint scanner and a keypad. The device uses a high-quality OLED display that activates as soon as you get close to it, so there’s no energy-wastage.

Fingerprint scanners are notorious for not always being able to identify the prints of children and the elderly. This is not the case with Ultraloq’s best electronic door lock. Scanning takes place in less than half a second and is always reliable.

The lock can store and recognize up to 95 different fingerprints. You can add or delete users directly from the display in a couple of moves and control who has what privileges.

While the auto-locking feature and the passage mode are standard features for most high-security door locks, Ultraloq also offers a rather interesting lockout mode that suspends all other entry methods and allows only mechanical keys.

The anti-peep mechanism for the keypad is simple but ingenious. You can type as many digits as you want as long as you type in the right sequence at some point. That way, anyone spying on you won’t be able to guess your code. Ingenious, right?

Compatibility & Use

It may not be the best door lock in terms of features, but its body is made of one piece and is completely waterproof and dustproof. There is also a secret keyhole at the bottom that you can use in case of an emergency.

The battery lasts up to a year, and the lock has a built-in detection system that sends you an alert when the battery is reaching its end — features that aren’t found in some of the best door locks for home security.

You can use the app to see a list of users and get a detailed report of all their comings and goings. However, to unlock your home, you don’t even need to open the app.

With an iPhone, you can unlock the door by knocking four times on your phone, while with Android, all you need to do is shake the device. It’s contending for the title of the best digital door lock on the market.


The cost of the Ultraloq UL3 BT starts at $174.77, but you can find better deals on Amazon and eBay websites. The box includes all the necessary mounting equipment, including the instruction manual, batteries, three backup keys, and a screwdriver to fit it all together.

Frequently Asked Questions (FAQ)

What is the best door lock brand?

It would be hard to pinpoint which brand of door locks is the best since we all have different needs and priorities.

However, among all brands, Schlage is one of the most sought after in the international lock industry. They offer a wide variety of door locks, including electronic locks, doorknobs, deadbolts, and handle sets made from premium metal. Durability is a key element of the brand, and so is an easy installation.

The company also offers a Limited Lifetime Warranty. Although their products can be quite pricey, you’re guaranteed to get your money’s worth if you really value safety above all else.

What is the most secure lock for a front door?

A reliable front door lock is a must-have in home security. When it comes to providing safety, we think a smart door lock is a tough door lock to beat. It allows homeowners to go keyless.

Additionally, with a smart door lock, you can unlock your front door using a smartphone app and grant temporary access to visitors, dog walkers, cleaners, and more.

What’s more, you can unlock it remotely, and you will be notified if someone enters your home. It is also easy to install and is compatible with other technologies in your home, such as voice assistants.

What are the most secure door locks?

Whether you’re planning to install a traditional or a smart door lock, security is almost always top of mind. When it comes to the types of door locks that offer the best security, deadbolt and mortise locks make it to the top of the list.

Deadbolt locks have a locking mechanism that protects against physical attempts to break in, such as using a knife or any other hand tool for picking security door locks. On the other hand, mortise locks have an intricate system that makes them a powerful lock for external doors.

If you’re looking for specific door locks and brands that provide the most security, the August Smart Lock Pro and the Schlage Sense Smart Lock are the best on the market right now.

How can I make my front door more secure?

Your front door is one of your home’s main lines of defense against burglars and other malicious forces. A sturdy and secure front door provides good protection, but the following additional measures can be taken to make your front door more secure:

1. Make sure your front door has a solid core. This makes it harder for burglars to break or kick in.

2. Install a deadbolt lock. The best deadbolt locks to install are those that don’t have any exposed screws or can only be locked or unlocked from inside your home.

3. Fortify existing locks by adding cylinder guards and replacing old strike plates.

4. Install a peephole, preferably a wide-angle one. When someone knocks on your door, this will allow you to take a peek at who it is, thereby reducing the risk of malicious people forcibly entering your home when the door is already half-open.

How safe are smart door locks?

Critics have divided opinions on the issue of whether smart locks are safe. Pretty much any smart device in the world can be hacked, and smart locks are no different. With a bad product, you will be much more exposed and susceptible to attacks.

However, if you choose a reliable door lock, such as the ones we listed as the best door locks, you will have a much better chance of dealing with problems if they arise.
