One of the benefits of introducing a smart lock is that you don’t have to carry a key with you. There is no need to put in and take out the key when unlocking and locking, and you do not have to rush to find the key in front of the door.

In addition, many smart locks have an auto-lock function that can be locked automatically even if you forget to close the key. Among them, there is a lineup of items that keep a history of key opening and closing, and models that show unlocking and locking in real time.

Be careful not to run out of batteries on both the smart lock side and the smartphone side. Smart locks can be prevented if the model notifies the smartphone when the battery is about to run out, but be careful when the smartphone battery runs out.

  • How to choose a smart lock

There are many types of smart locks on the market, so be sure to check them out.

  • Select by mounting method

  1. Paste type

A smart lock that can be attached to the door with double-sided tape or an adhesive sheet is a sticking type. The advantage is that it is easy to introduce even for rent because the door is not easily damaged and can be easily restored to its original state. No specialized knowledge or difficult DIY is required, so even beginners can easily install it.

Depending on the material of the door, the disadvantage is that it can easily come off unless it is firmly fixed. Recommended for those who prioritize ease of installation and removal.

  1. Cylinder replacement type

The cylinder replacement type removes the cylinder part of the existing key and introduces a smart lock in the vacant space. It can be installed in a rented room as long as the removed key can be replaced without additional holes or screws.

There is almost no cost for the type that can be replaced by yourself. If it is a type of cylinder that you have to ask a contractor, additional cost will be incurred. Recommended for those who want to firmly fix the smart lock even for rent.

  1. Drilling work type

The drilling work type is to make a hole in the door and attach a smart lock. In most cases, it cannot be installed in rental apartments or condominiums because it cannot be restored to its original state. If you do not have DIY knowledge or experience, you will have to ask a contractor, so it will be costly.

On the other hand, it has the advantage that it can be used in a stable state because it is fixed by making a hole for the smart lock. This is the recommended installation method if you can DIY your home.

  • Smartphone operation type

The smartphone operation type is characterized by operating a smartphone with a dedicated application installed to lock and unlock. If you have a smartphone at hand, you can operate it wherever you are, so you don’t have to worry if you forget to lock it.

Also, if it is a thing that records operations via the application, it is also attractive to be able to check information such as when it was last unlocked and who operated it. This type is recommended for those who are worried that they have forgotten to lock it.
