Unlocking the front door and repairing strike deformation due to indoor confinement

"I was trapped inside without thumbturn turning"

It is also a rare phenomenon as far as I can hear the contents.Anyway, I'm heading to the scene, but I think it's interfering with something.

After arriving, I asked him to come to the front of the door from the intercom, listened to the phenomenon, and started work.

There is no way to pull the door, so I had to push the door from the outside and turn the thumbturn from the inside.The door can be unlocked, and when you check around the lock, the strike plate is greatly deformed.

I don't know why, but I removed it, modified the shape, and the work was completed.
