Smart locks are convenient devices that let you manage locking and unlocking with a smartphone instead of a physical key. Their use in detached houses is increasing, but many people wonder whether they can also be introduced in rental properties. This article explains the features and types of smart locks, as well as recommended products that can be used in rentals.
What is a smart lock? How does it work?
A smart lock is a system that manages door locking and unlocking using devices such as a smartphone.A smartphone with a dedicated app installed communicates with the device attached to the door via Bluetooth Low Energy (BLE) and similar technologies to lock and unlock the door.
Many smart locks come with anauto-lock functionthat automatically locks the door when it closes and helps prevent you from forgetting to lock it. The time until locking can also be set as desired.
In addition to smartphones, some products support keypads and IC cards as locking tools, and they offer various operating methods such as automatic unlocking using GPS functions.
What types of smart locks are there?
There are four main types of smart locks, and you can choose one that matches your lifestyle.
Smartphone type
This type is operated through a dedicated smartphone app. Because it uses direct Bluetooth communication, it does not depend on a Wi-Fi environment.It is relatively affordable and recommended for people introducing a smart lock for the first time.However, you do need to take out your smartphone to operate it.
Hands-free type
Because it unlocks automatically simply by approaching the door, there is no need to take your smartphone out of your bag or pocket.It is convenient when both hands are occupied or when you are carrying a small child. However, if the communication condition is poor, unlocking may take more time.
Multi-device type
It allows the lock to be opened and closed in multiple ways, including smartphone, IC tag, IC card, and PIN code.It can also accommodate family members who do not use smartphones.
AI assistant type
This smart lock supports voice control through smart speakers and services such as Siri.You can lock and unlock the door without going to the entrance, and remote operation is also supported. The installation cost is higher, but this type offers the greatest convenience.
What are the benefits of introducing a smart lock?
Smart locks offer many benefits that conventional keys do not.
No need to take out a key
Even when both hands are full, such as after shopping, you can unlock the door smoothly. With a hands-free type, you do not even need to take out your smartphone.
Useful for security and monitoring through access records
You can check the lock and unlock history in the app,which is useful for confirming when children return home and for checking suspicious entry attempts.It is also effective as a security measure for households raising children.
Prevent forgetting to lock with auto-lock
Because the door locks automatically when it is closed,you do not need to worry about forgetting to lock it.It also provides peace of mind when leaving home on a busy morning.
Reduce the risk of key duplication
Because there is no keyhole, duplication is difficult, andbecause there is no need to carry a physical key, the risk of loss is also reduced.
Easy to create and manage spare keys
By issuing one-time passwords and setting expiration dates,you can manage time limits and permissions in detail, which strengthens security.
What should you be careful about when introducing a smart lock?
Even convenient smart locks have points you should understand before installation.
Dead batteries and weak signal
If the battery in your smartphone or the smart lock itself runs out, you will not be able to operate the lock.Carry a mobile battery and make use of battery-level notifications from the device itself.We also recommend carrying a physical key as a backup.
Risk of being locked out
Due to the auto-lock function,if you leave with your smartphone still inside, you may lock yourself out.You should be careful even when stepping out briefly, such as to take out the trash.
Installation and maintenance costs
The typical product price ranges from 10,000 to 50,000 yen. If cylinder replacement is required, installation work may add around 3,000 to 5,000 yen. Some products also have a monthly fee.
Some doors are not compatible
There are cases where installation is not possible on thumbturn-style doors or doors with integrated doorknobs.Be sure to check the shape of your door before purchasing.
Hacking risk
Because these products use Wi-Fi and Bluetooth communication, the risk of hacking is not zero. It is important to choose a product with proper security measures before installation.
Can a smart lock be installed in a rental property?
Smart locks can also be introduced in rental properties.If you choose a type that attaches with double-sided tape, it can be installed without drilling or construction work.
However, because tape marks may remain when you move out,be sure to obtain permission in advance from the landlord ormanagement companybefore installation.
Please note that some locks may not be compatible, such as those with an integrated doorknob and thumbturn or special shapes with a thick knob.
What are the three points to check before installation?
Before purchasing a smart lock, check the following three points.
How to handle dead batteries
Choose a product with a battery-level notification function, and you will have greater peace of mind if it also comes with an analog key.
Risks of unlocking with a smartphone
The stability of the Bluetooth connection depends on the smartphone model and environment.Be careful that other Bluetooth devices, such as Bluetooth earphones, do not interfere.
