"Lost key, Unlocking the entrance door"
It is a luxury one-room apartment located in a corner of the center of Yokohama city. Although it was usually declared as a thumbturn, it was equipped with a crime prevention thumbturn. It's a relatively new apartment, so it's a natural equipment.
Push-pull plate lock with one locking point. It is a lock that I like more than the grip handle type.
However, the distance to the door scope was in a delicate position, so I changed the tool twice. This is why it took me so long to set it up. In the end, I proceeded with the unlocking work by adding a 2mm extension to the "Short-Short Tool".
