USHIN SHOWA QDJ696 double lock, Lost key, Unlocking the entrance door

"I lost my key somewhere on my way home."

The client was depressed and asked, "Why at this time...?", but please wait a moment as I will be able to enter the room properly.

It was a pretty dark scene after sunset. Since this is a relatively new property, I thought it was a security thumbturn, but when I checked the images, it turned out to be a standard thumbturn. It was a single-family entrance door and cylinder set, which is rare for an apartment. It's a pretty elaborate design.

The work involved unlocking two locks, but it went fairly smoothly.
