When I was in my twenties, living alone, I completely lost the habit of locking my room. He then moved in with his wife and had to lock it up.

In the end, I couldn't regain the habit of locking, but instead I introduced CANDY HOUSE's smart lock "SESAME (Sesame) mini" with an auto-lock function in 2018.

It can be attached by simply sticking this device to the key of the entrance, and if it is linked with a smartphone, it can be locked / unlocked with a single tap of the application. Furthermore, it has an "auto-lock" function that automatically locks a few seconds after unlocking. After installing this machine, I never forgot to lock the key (prior to the introduction, the rate of forgetting to lock was high).

In December 2020, a new model "SESAME 3" was released for the smart lock that smartly locks and unlocks and eradicated one of the causes of marital quarrels in our home. The price is 6,380 yen, which is quite reasonable compared to similar products from other manufacturers.
