MIWA U9.LSP＋BH, Lost key, Unlocking the entrance door

"Lost key, Unlocking the entrance door"

It was a request to unlock the door first thing in the morning.I was a little lost because the apartment name was not specified, but I arrived safely.

When checking the cylinder collar, the main lock appears to be LSP, and the lower auxiliary lock appears to be DZ(BH). The thumbturn seemed to be standard, so the work was usually completed with unlocking.
