SHERLOCK2 B5 Unlocking the entrance door with security thumbturn

"Lost key, Unlocking the entrance door"

When the client got home last night, he realized that he had lost his card key.

It seems that the estimate of the contractor he looked for on his smartphone was a ridiculous amount. After doing something about it overnight at a manga cafe, it seems that they decided to make a request this morning. Thank you.

It is a luxury rental apartment with security in mind, requiring a card key to access elevators and stairs.

I heard that the shape of the thumbturn is a normal thumbturn, but I felt a sense of incongruity as soon as I started working on it.

When I hear it again, it looks like a thumbturn with a switch. I switched to a special unlocking method, but it's dark and out of focus with a normal light, so I can't see it well.

I decided to use the extra LED, and after that I was able to proceed smoothly.
