MIWA UR.LA, the thumbturn did not turn and I was trapped indoors.

"Thumbturn malfunction inspection and repair"

I tried to talk to him over the intercom to check on the situation, but I couldn't get a hold of him, so I asked him to come to the door. We decided to talk through the door.

It certainly looked like the door was stuck on something. There's no door post, so you can't pick up your keys, and there are no windows nearby. First, I decided to have the child rotate the thumbturn while pushing or pulling. Then I was able to successfully unlock it.

I will check each part, but there is no problem with the cylinder set. There is no interference with the door frame. When I looked at the front, I could see the scratches, but the strike also felt strange. It was greatly deformed. This deformation seemed to be interfering with the front and affecting the movement of the deadbolt.

Remove it, correct the deformation, and you're done. In the end, I didn't know why this happened.
