MIWA PR.LDSP thumbturn Unlocking and repairing the entrance door due to poor construction

"I can't get out of the room because the thumbturn doesn't turn"

It is said that he moved into the same apartment from April this year, but it seems that he was stiff from that time. Arrive at the site and check the situation over the intercom. Even if there is a window on the aisle side, it cannot be opened (when I checked after unlocking it, it was all blocked by the interior renovation). There was no doorpost, so I went around to the back to pick up the key, passed through a narrow gap, and picked it up from the side of the sweep window.

Even if you move the door back and forth, you can't confirm that it interferes with the strike, so it may be a defect in the main body case, or interference with the thumbturn mounting screw if it's an LSP.

Normally unlocked with the key received from the outside. (It's pretty hard. Is it aging?)

Looking at the front, it is LSP engraved, but the body was forcibly attached with LDSP processed.Also, the thumbturn is installed incorrectly and the setscrew is popping out.The front was also lifted.

It was bad work by the replacement worker.Sadly, this kind of rudimentary and sloppy work is a common occurrence these days.

Tighten it about 1.5mm more, reinstall the thumbturn in the standard position, and finish the inside of the case with a special spray cleaning and lubrication.
