What is a smart lock?
A smart lock is a dedicated device that can be unlocked and locked from a smartphone. It can be attached mainly to the front door key so that it can be unlocked hands-free by location information or Bluetooth, or it can be auto-locked.
You can unlock and lock without removing the key, and you don’t have to worry about forgetting to lock or lock it. It is also attractive that you can share the master key with your family and friends and check the unlocking / locking history.
Depending on the product, you may be able to lock / unlock with your fingerprint, PIN, or IC card in addition to the operation with the app.
Advantages and disadvantages of smart lock
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.
Furthermore, even if you lose your smartphone with a smart lock, you can manage your keys with your ID and password. You can download and use the app on an alternative device or another smartphone.
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.
Also, when you install a smart lock that has an auto-lock function, you may be locked out if you go out with your smartphone at home. Keep in mind that if you live alone, you will have to contact the management company.

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.
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.
