"Unlocking the entrance door due to card loss"

It's a police officer meeting. There seems to be a door scope, so I proceeded with normal unlocking.

However, there was something wrong with the feel, so when I asked the client, he said, "It's not black, it's silver."

I had no choice but to give up on a genuine SHERLOCK child lock, but when I looked into it, it was a "door knob type with a constriction" that I had never seen before. It wasn't child lock.

It's not the EGG of AiAi either. I searched and got no hits.

It is said that it is not push and turn, so I try to apply torque and turn it, but the lever ratio is not enough.

I tried to search unlocking with a temporary card, but it reached the time limit. Work with this method is on a losing streak.

By the way, there is a knob type rotating thumbturn like EVVA made overseas. I have a tool for this, but since I don't have a camera, I couldn't work from the door scope alone.

Due to this incident, I decided to remodel this tool with a camera in earnest.

Even so, SHERLOCK's card search unlocking doesn't go smoothly. I need to study.
