MIWA LB.DVF.CP-B5, Lost key, Unlocking the entrance door

"Lost key, Unlocking the entrance door"

This is a 10-story apartment building located in the center of Yokohama's downtown area. It is not considered to be a standard thumbturn.

When I checked with the camera, it was a security thumbturn B5. It's the usual special unlocking method, but since the distance from the scope is short, I decided to proceed step by step using a short type tool.

However, the tool does not go in through the scope hole. I can't turn corners. Apparently there is a magnetic shelf attached near the scope.

If you can avoid that part and approach it, all you have to do is turn it. I was able to unlock it shortly after.
