MIWA WEST916(BH).LDSP, Lost key, Unlocking the entrance door

"Unlocking the entrance door because I lost my bag"

Are you a student at a nearby university? It seems like I lost my whole bag. Since it was not possible to confirm the identity of the person, the case was brought to the police in the presence of a police officer.

The cylinder collar rotates and you can see the threaded part, so I guess it's a BH type. The work was completed with normal thumbturn unlocking from the door scope.
