Unlocking the inward-opening living room door and replacing the Nagasawa GM empty lock
"A request to unlock the interior door. There is a person stuck in the living room." There is a lever that does not work with the latch bolt. I moved to another room and closed the door. However, when I returned to the living room, it seemed like the door had suddenly been locked. A person who cannot move is trapped in the living room […]
ASSA ABLOY Scandinavia Cylinder Inspection
"The key is difficult to turn. I would like an inspection." A high-class residential area in Setagaya. It was a detached rental property.

This is (counterclockwise […]

It turns both ways to lock and unlock, but I can't seem to get the key out [...]

Unlocking the entrance sliding door and exchanging the kitchen door knob

A little over 40 tsubo with 4,000 million land is cheap! Apparently it was purchased second-hand, but it is a nice-looking detached house with a sliding door at the entrance. However, he wants to open the kitchen door instead of the front door. The key to the entrance […]
