The door was closed during DIY work to replace the toilet lock

"Unlocking the toilet due to DIY carelessness"

It seemed that the house was converted into a group home and operated. It is a typical old detached house.

It seems that the toilet key was not working well, so the man were trying to replace it with a new one. The door was closed at that time.

Looking at the site, it seemed that turning the cam with a screwdriver would have been sufficient, but that was not the case. Latch operations don't work either. It looks like the internal parts of the tubular are damaged. It's a common case, but in this case you need a hole saw.

That's a pretty big estimate. It seems that he was not careful during the DIY work, but in the end he was able to understand.
