A smart door lock is one of the most important parts of a connected Smart Home. With a smart lock, your smartphone becomes the key to your home. 

You can see who is locking and unlocking your door and when, and you can send guests a temporary authorization or a digital key to their smartphone. 

Most smart door locks are now compatible with smart home systems and assistants such as Amazon Alexa. But which door locks are best suited for Alexa? 

Here are the 4 best smart door locks compatible with Alexa:

August Smart Lock Pro + Connect

With the August Smart Lock Pro + Connect* you get a smart door lock that opens automatically when you go to the door and closes again when you leave. 

This lock is also ideal for tenants because it is easy to install without changing the cylinder or key of the existing front door. This way it also works with your already existing keys.

Features 

The August Smart Lock Pro + Connect does not take first place among the Alexa compatible door locks without reason. The best features are listed here:

• Open the door without a key: Probably one of the most important features of this smart door lock is that you can open and close your front door without a key. You can either do this via the app at the push of a button or you can set the automatic unlock and lock, whereby the door lock opens automatically when you come to the door and locks again when you leave. I don’t know about you, but it happened to me before, almost every time after shopping, that I either had the key in the wrong pocket or had to drop the shopping bags to unlock the door anyway. The smart August door lock also eliminates this. 
• Lend digital keys: You can send temporary permissions to others to use your door lock. So you can give guests or the cleaning lady access to certain time windows in which they can access your house via their smartphone. After the set time, this authorization expires again and you can no longer open the lock with this temporary digital key. 
• Open and lock the door from a distance: You can use the app to open or lock your front door from anywhere. If someone is at your door and you are at work, for example, you can unlock the door from a distance. This would be practical, for example, if you are expecting guests, but they come too early and you are not yet home. So you can open the door for them from afar and they don’t have to wait for you in front of the closed door. On the other hand, you can also open the door to family members from a distance once they have locked themselves out. 
• Lock notifications: You can set the app to send you a message every time someone enters your house. If you live in a house or apartment with several users, for example with your family, you can see whether someone has already come home or not. This is especially helpful if you have a full-time job and kids because you always know exactly when the children are at home and when they are not.
• Door sensor: The app allows you to see not only whether the door lock is locked or open, but also whether the door is open or closed.
• Smart Home compatibility: The August smart door lock is compatible with the most popular Smart Home systems. In addition to Alexa, this also includes HomeKit, Google Assistant, Z-Wave, IFTTT, and Nest. You can ask Alexa to both lock the door, open it and check if it is open or closed. 

Installation and Setup 

The smart door lock from August comes with everything you need for installation. 

The new version includes a universal plate for mounting. Previously there was a separate mounting plate for each type of door, which only confused. The assembly itself is very well explained and can be done within a few minutes. You don’t need to bring professional staff to your home. This little video from August sums up the entire assembly process perfectly:

Data Protection and Security 

With door locks that can be opened via mobile phone, the question of whether this is safe or not comes up very quickly.

The August Smart Lock can be controlled via a smartphone with Bluetooth. This means that either you yourself or anyone who has received an invitation from you can only operate the door lock on the one smartphone with the invitation via Bluetooth and enter your house or apartment. 

But can this process also be hacked?

Of course, this question is the most frequently asked question at the manufacturer and is therefore of great importance to them. The communication between smartphone and door lock is doubly encrypted. This actually makes the lock more secure in the end than a normal lock with a key!

Danalock V3 Smart Lock

From Denmark comes a great smart door lock which can be operated with the smartphone and with Alexa and Co. 

The Danalock V3 Smart Lock* integrates perfectly into an existing Smart Home system. With ingenious features such as geofencing, auto-lock function, key permissions, etc., this smart door lock has truly earned its place in this list.

Features

Here are the best features of the Danalock V3 Smart Lock listed:

• Long battery life: The battery life of this smart door lock is truly remarkable. Four CR123A batteries last for up to 1.5 years of constant use. In comparison, the batteries in our 1st place, the August Smart Lock Pro Connect* only lasts 6 months. 
• Invisible from outside: Outside your apartment or house, you cannot tell that you have a smart door lock installed on your door. It only replaces the inside of the locking mechanism and the inside of the lock. This means that you can also keep your existing door handles and the lock on the outside of the door. 
• Compatibility with many doors: Danalock has designed its door locks to be compatible with a wide range of doors. These include European, Scandinavian and American doors. DanaLock is a company from Denmark, so the coverage of all these variants makes a lot of sense if you think about the marketing range.
• Alexa and Smart Home compatibility: A smart door lock would not be really smart without integration into a Smart Home system. That’s why Danalock offers a range of connectivity options including Alexa, Apple HomeKit, Z-Wave, ZigBee, and Samsung Smartthings.
• Multi-User Support: If you want to use the smart door lock with your whole family, everyone has to log in with their smartphone. This means that several people can be registered with the door lock at the same time without the need for several keys. You can also send friends temporary access to their smartphones – without an app.
• Geofencing and Auto-Lock & -Unlock: Geofencing allows you to set the door lock to query your location or the location of your smartphone and automatically open the door as you approach the door lock. But there are also possible combinations. I have set the door lock so that it unlocks automatically when I get closer, but no matter who opened the lock or when or where he was, it always locks itself again automatically after 30 seconds. So I can also be sure that other users, such as children, do not forget to lock the door. 

Installation and Setup

The installation of the Danalock was really easy. A small installation guide is also included, so you only need a few minutes to install the smart door lock. 

And if that’s not enough to explain to you, you can also find assembly videos and a complete user manual as a PDF file on the Danalock website.

Unlike the August Smart Lock Pro Connect*, this smart door lock comes with different mounting plates. So there is the right mounting plate for every type of door. Just like the other smart door locks in this list, you don’t need professional assistance to install this Alexa door lock. The instructions are very simple, you just need normal tools and you can’t really do anything wrong. Once you have the installation behind you, all you have to do is download the Danalock app, install it and connect to the door lock. Then you are ready to adjust the door lock and connect it to Alexa!

August Smart Lock

The August Smart lock* is an inexpensive alternative for getting started with a smart locking system for your front door. Just like most of the other locks presented here, it replaces the back of your existing door lock with a smart module. So you can make your door lock smart without having to change the cylinder or your keys.

Features

The August Smart Lock has some great features that make it great value for money due to its low price. The most important features are listed here:

• Smart Home Compatibility: Like the other August smart door locks, the August Smart Lock standard door lock can also connect to the most popular Smart Home systems. These include Amazon Alexa, Google Assistant and so on. Especially the use with Alexa is very easy to set up and very comfortable to use.
• Doorsense: With this feature, the door lock knows when someone opens or closes the lock. It can also tell whether the door is open or closed. So you can always make sure that your door is not only closed but also locked.
• Smartphone = key: Of course, this smart door lock can also be operated via the smartphone. So the smartphone becomes the key. The great thing about it is that you don’t have to carry your key with you and you don’t have to make new ones if you want to give someone permission to enter your house or apartment. 
• Authorization for guests: Within the app, there is a guest list that you can fill with friends, family, and other guests. When you select a guest, you can give him permissions for your door lock for a limited time. So if you’re expecting guests but need to work longer, you can let them into your house without them having to wait outside. This feature is also ingenious for owners of holiday apartments. The door lock can be integrated into Airbnb, so you don’t have to give your guests a key but can send them the link to download the app. This allows them to lock and unlock the doors themselves with the smartphone for the limited time they are there. You can even let the app inform you when the guests leave so that you can clean up and tidy up. 
• Auto-lock and Auto-unlock: With this feature, you get your own butler to open and close the door. The door lock notices through this feature when you approach the door and when you leave again. As soon as you are close enough to the door, the lock opens by itself and closes again when you leave. 

Installation and Setup

The August Smart Lock is very easy to install. All you have to do is remove the existing back of the lock, install the new one and mount the August Smart Lock on it.

At first glance, the design looks a bit clumsy, since the entire lock is about as wide and high as a smartphone and twice to three times as thick. Nevertheless, it is modern and simple in design.

The smart door lock gets energy from 4 AA batteries, hence the size. Most other smart door locks work with smaller batteries, which results in a smaller case but also higher costs. On the August website, you can see which locks this smart door lock is compatible with. 

Once you’ve installed and powered the Alexa compatible door lock, all you have to do is download the app and connect your smartphone to the door lock. As with most other smart home devices nowadays, the rest is child’s play. The app explains very easily the installation process and the different settings you can make.

Schlage Connect with Alarm

Schlage is not a small company that was born out of the Smart Home hype, but a traditional company that was founded in 1920 in the United States. 

In the field of door locks, they have been on the road for almost 100 years, which means you expect – and get – well-thought-out quality and good service!

With the Schlage Connect*, you get a complete security system for your front door. It is not only a smart door lock but also becomes a complete security system due to the built-in and very loud alarm. 

The only drawback of this door lock is that you need a Smart Home Hub with Z-Wave to use the full potential and smart features like the Alexa connection. If you’ve had some smart home experience, you’ll probably already own a Smart Home Hub anyway – if not, the Samsung Smartthings Smart Home Hub* is our clear recommendation for you.

Features

The most important features of the Schlage Connect door lock are listed here:

• Built-in alarm: The built-in alarm has three different functions: Activity message and alarm in case of forced opening and manipulation. The activity detector is actually not a real alarm but rather a quiet beep as soon as the door is opened. The tamper alarm gives a 90 decibel alarm for 15 seconds when someone tries to crack the number combination. And finally, there is the true alarm with a piercing 90 decibel sound, which is triggered when someone forcibly gets in or wants to get in. 
• Different designs: The Schlage Connect is available in different designs and colors. Matching door handles and other accessories are also available. It is available in nickel, matt black, shiny chrome, matt chrome, and aged bronze. 
• Touchscreen: The touch screen on the outside of the door is designed to minimize fingerprints and smudges. This way the keypad will never look dirty. The touch screen feedback feels good and very reactive. If the input is correct, the touchscreen lights up green, if the input is incorrect, it lights up red.
• Autolock: The Auto-Lock feature automatically closes the Schlage Connect after 30 seconds. I’ve used this feature on every smart door lock that offers it so far. It simply offers more security and no one can forget to lock the house. Especially in a household with children, this is very useful, because children rarely think about such things.
• Highest safety standard: The Schlage Connect is certified with ANSI/BHMA Grade 1. This is the highest possible safety standard for your home. 
• Holiday mode: In this mode you can deactivate all codes for the duration of your holiday. You can then only enter the house with a real key. In this holiday mode, the door lock resembles an alarm system, since there is only an alarm of itself if someone wants to gain entry, but nobody gets access anymore with his code.
• 1-year battery life: The Schlage Connect is powered by 4 AA batteries. This should supply the smart door lock with electricity for about a year. Schlage Connect also automatically detects a low battery level and notifies you well in time with an audible signal that the batteries need to be changed. 
• Smart Home Compatibility: The only real disadvantage of this smart door lock is that you need a Z-Wave compatible Smart Home Hub to use the smart features of the door lock. One such hub would be the Samsung Smartthings Hub*. The ingenious thing about it is that you can not only control the door lock via Alexa but also “program” smart chain reactions with other smart devices. So you can program your smart light in the hallway or in front of the door to turn on when someone uses or opens the door lock. 

Installation and Setup

The Schlage Connect looks more complicated than it is. In fact, it is even suitable for beginners as far as smart home or smart locks are concerned. Assembly and operation are also very user-friendly and can be carried out without special electronic or technical know-how.

The door lock is designed to be compatible with virtually all doors. All kinds of accessories for mounting are included in the scope of delivery. But don’t worry – everything is very descriptive and easy explained in simple language and images.

Nevertheless, the installation takes a little longer than the other smart door locks presented here, because you have to install 2 things and not only the rear part.

As soon as the assembly is finished, you can start assigning codes immediately. These codes are the combination of numbers that must be entered on the touch screen to open the lock. You can assign the codes either on the device itself or via a Smart Home Hub*.

A code consists of four to eight digits. There are a total of 30 codes that can be assigned simultaneously. So you have enough for family, friends, craftsmen, dog sitters, etc..

Pros & Cons: Schlage Connect

Wifi, Bluetooth or Z-Wave? 

With the exception of the Schlage Connect, smart door locks usually don’t make your home any safer, but they make it more comfortable and easier to control. Using the digital keys, you can open and lock the door remotely, sending friends, family or other visitors a digital key to their smartphone for a limited time so they can enter your house.

Of course, you can also use a normal key to open your door. But every time I go shopping, I am happy that I have made the decision to buy a smart door lock because it is simply brilliant not to have to put down all shopping bags to enter the house.

Nevertheless, there are sometimes large differences between the various smart door locks. There are those that no longer use normal keys and can only be used via Bluetooth, Wifi, or Z-Wave or a combination of all. 

To connect to your Smart Home System or Smartphone, the Smart Door Lock requires one of three common communication protocols: Wifi, Bluetooth or Z-Wave.

Only when it connects to your Smart Home via one of these protocols can you use your favorite digital assistant, such as Amazon Alexa, to control it via voice.

There are advantages and disadvantages to each of these connection types, and we recommend Z-Wave for Smart Home Integration:

• Bluetooth: The big advantage of Bluetooth is that it is very energy efficient. Most smart door locks that connect via Bluetooth have a battery life of at least one year. The disadvantage is of course that the range of Bluetooth is very limited. Therefore you can only use the lock when you are near your house or inside it. To do this, you need a smart door lock that connects directly to your smartphone via Bluetooth, not a hub. However, you will need Wifi or Z-Wave if you want to control the door lock from work or open the door for others when you are not there.
• Z-Wave: Door locks that communicate via Z-Wave need a Smart Home Hub to which they can connect. The Hub translates the Z-Wave signal for your router, allowing you to control the door lock from anywhere. For all Smart Home devices based on Z-Wave as communication, our clear recommendation is the Samsung SmartThings Hub*. And this is actually the only disadvantage of Z-Wave – you need your own hub. But if you’re already in the smart home game anyway, it’s very likely that you already have one or will sooner or later need one anyway. 
• Wifi: There are also smart door locks that can connect directly to your Wifi. So you can operate the door lock from anywhere in the world as long as you have an Internet connection. The disadvantage of this is that most door locks have the Wifi function only through an addon which must be installed separately.

Bottom Line 

We hope you found the perfect Alexa compatible door lock for you in this article.

As you will have noticed, there are a few ingenious features that all of the door locks presented here have in common. Nevertheless, there are differences in their connectivity and security.

A smart door lock is especially worthwhile for households with several people since you can check from anywhere who came home, when they left and whether the person really closed and locked the door. I already had several situations in which I was very happy to have a remotely controllable front door lock. 

Who hasn’t had to turn around on their way to vacation because they forgot to lock the door? Who hasn’t had their hands full when they come back from shopping? 

It also gives you more flexibility when you have or expect guests at your home. On the one hand, you can open the door for your guests even when you are not at home or you can simply give them a digital key to the smartphone that is only valid for a limited time. So your guests can open and lock the door as long as they are with you.
