U9.HMD Unlocking the front door due to lost key

"Lost key, Unlocking the entrance door"

He said that he had just returned from Kyushu.I don't know where I lost my key.

There is a baseball field just 100 meters away.We were in the middle of a night game.A roar of support rings out.

It seems that there is no noise countermeasure.

After checking whether it was left-hand or right-hand, I determined the unlocking direction and proceeded with the work.
