Do you know one of the smart home devices, the "smart lock"? It is an item that can be unlocked and closed with a smartphone without using a physical key. More and more people are using smart locks not only in offices and vacation rentals, but also in their homes. In this article, we will introduce 11 smart locks recommended for beginners, including how to choose a smart lock. Please refer to it and try to get a smart security item!

What is a smart lock?

Smart locks are devices and systems that use devices such as smartphones to open, close, and manage locks without using physical keys. It mainly consists of a device attached to the door and a dedicated smartphone application.

Many smart locks communicate with the lock side using Bluetooth Low Energy, etc., and the device physically unlocks or locks the door when the smartphone application is used to unlock or lock the door. Products with Wi-Fi connectivity can be remotely managed, such as checking if the door is locked from outside or unlocking it for guests who are away. In addition to opening and closing the key, most models are equipped with a function to issue a duplicate key for guests to use and an auto-lock function.

Smart locks first started to attract attention in the United States, and at this stage they are more popular than in Japan. In the United States, smart home devices such as smart speakers are used in many homes, and smart locks are one of them. In Japan, 2015 is called the first year of smart locks, and each company has released smart locks for Japanese homes one after another.

Currently, in Japan, it is being used for share houses, rental conference rooms, co-working spaces, offices, hotel and private lodging check-ins, real estate previews, etc., and is gradually being used in residential areas.

There are mainly two types of smart locks, "replacement type" and "replacement type", and the installation method is different for each.

The post-installation type is affixed with adhesive tape or the like so as to cover the thumb-turn (a knob on the interior side of the door that opens and closes the lock). can be used without damage. There are also disadvantages such as the tape rarely peeling off and falling, and because it is larger than the thumb turn due to its structure, it stands out.

On the other hand, in the replacement type, the existing lock is removed with a screwdriver or the like, and a smart lock device is installed instead. Many of them are thin and look neat. There are products that can be unlocked not only with a smartphone app but also with a password or IC card, and products that claim that the speed and accuracy of Bluetooth communication are higher than those of retrofit models. Since it requires construction work, it is more difficult to install than the retrofit type, and some require drilling holes in the door, so it may be difficult to install in rental housing.

・Hands-free and auto-lock make unlocking and locking easier

Most smart locks have hands-free unlocking and auto-locking features. Using your smartphone's GPS and beacons (a function that identifies your position within a radius of 10 to 100 meters), you can automatically unlock the door by simply approaching the door with your smartphone in your bag or pocket, or when your smartphone is inside your home. It is a function that locks when it senses that you are away from it. You don't have to fumble around in your bag or pocket in front of the door to retrieve your keys, which saves you a lot of hassle in your daily life.

・Improved security

The auto-lock function will prevent you from forgetting to lock the door. With a smart lock equipped with Wi-Fi connectivity, you can use the app to check the history of who unlocked and when you unlocked it, and receive notifications when it is unlocked, so you can keep your family and belongings safe. connected to.

・Share key

Through LINE, email, etc., you can pass your house key to a guest like a "one-time password" that is valid only for a specified time. Shared offices, co-working spaces, rental conference rooms, private lodgings, etc. eliminate the need for manned reception desks and are conveniently used to save costs. Even at home, it is useful when you have visitors when you are away or when you use services such as house cleaning.

Giving someone a physical duplicate key can be a big risk. Depending on the key, if you know the "key number" engraved on the key itself, you can create a duplicate key even if you do not have the key at hand, so there is a possibility that the key will be copied even if it is for a short time.

On that point, with a smart lock, you can limit usage time, reset permissions, and check usage history, so it's much safer than handing over a physical key.

・Don't worry if you lose your key

It is difficult to find a conventional key once it is lost, and even if it is found, there is a possibility that a duplicate key has been made. If you lose it, you basically have to replace the door lock.

But the key to a smart lock is your smartphone. With a smartphone, even if it is lost, it is relatively easy to find it with a tracking function like "Find My iPhone" on the iPhone, and if it is locked, the contents are less likely to be misused, so you can use another smartphone. You can also unlock it by logging in to the smart lock dedicated app.

In the unlikely event that your smartphone is not found, you can reset the access permissions of the smart lock, so you don't have to replace the entire lock.

・Smart lock, risk of running out of smartphone battery

There is a risk that you will not be able to unlock the smart lock if the battery of either smart lock or smartphone runs out. However, even if you have a smart lock, you can open it with a physical key, so you can avoid the risk by carrying the key with you.

Also, many smart locks send a notification through a smartphone app when the battery is about to run out, so you can replace the battery before it runs out. There is also a smart lock that automatically orders batteries and delivers them to your home when the remaining battery level is low by linking with Amazon.

In addition, since it uses a low power consumption communication method called Bluetooth Low Energy, many of them can operate for a long time of about half a year to a year with a few dry batteries, so you don't have to worry about running out of battery. would be good too.

・Cannot be installed depending on the shape of the door

In the case of a retrofit type smart lock, it may not be installed depending on the shape and size of the thumb turn. You can often check which thumbturns are supported and which are not supported on the official website, so be sure to check before purchasing.

By sending a picture of the thumbturn from the app or website, you can check in advance whether it can be installed, or send a special paper craft for confirmation free of charge, and if you can not install it after purchase, you can exchange or refund. Each company is taking flexible measures. There are also companies that 3D print custom adapters for special doors.

・Risk of communication failure and software failure

In 2017, the smart lock of the American smart lock system company "LockState" could not be unlocked due to an update problem. This can also be unlocked with a physical key, but it is not without fear of being locked out of the house.

In addition, as long as it has a communication function, it cannot be said that the risk of being hacked from the outside is zero. However, many smart locks use advanced encryption technology and claim to be highly secure. Some claim to have military-grade security.

・Hands-free unlocking

When you approach the door with your smartphone in your pocket or bag, the door will unlock without you needing to operate it. It learns the range of the house and unlocks only when you return home from outside the house, so it will not be unlocked every time you approach the door when you are at home.

Qrio Smart Lock is the old model of Qrio Lock introduced above. The product price is 18,000 yen (excluding tax), but since a new model has appeared, you can purchase it at a reduced price on Amazon, Rakuten, etc.

However, compared to the new model Qrio Lock, the performance is inferior in the following points.

・Beta version of hands-free unlocking

Compared to Qrio Lock, which officially implements hands-free unlocking, accuracy is lower. If you don't use hands-free unlocking, when you stand near the lock and your phone recognizes it, you'll be ready to unlock it, and eventually use your hands to unlock it.

・Auto lock is not immediate

Qrio Lock activates the auto-lock function the moment the door closes, whereas Qrio Smart Lock locks after a certain amount of time has passed since the door closed. I'm a little concerned about security.

・Large size

Qrio Smart Lock is slightly larger in size than Qrio Lock, and it may sometimes fall off even if it is attached with double-sided tape.

On the other hand, the following features are comparable to the new model Qrio Lock.

・Locking and unlocking operation from smartphone

・Creating and sharing duplicate keys

・Check the history of locking and unlocking operations from the app
