MIWA 10DAF+U1 Unlocking the entrance door by thumbturn

"Unlocking the entrance door by non-carrying a key"

I don't know why, but he seems to have forgotten his key. It was a luxury apartment in the city.

The client herself did not seem to understand well what the security thumbturn is. Since it was MIWA's PR.DAF, the U1 type security thumbturn would be standard equipment.

When I checked, I also confirmed the U1 type security thumbturn. Attach a non-slip to the special jig and proceed with the setup.

It took a while to get approval to start work, but I was able to unlock it immediately after starting work.
