Unlocking the entrance door that does not open from inside or outside

"Unlocking the entrance door"

I tried to open the door to go to work in the morning, but the thumbturn wouldn't turn and the door wouldn't open.Even if you go out from the veranda and try to open it with the key, it will not open.According to the information, it seems to be a relatively new property, but what is the cause?It's hard to imagine that the parts will deteriorate over time.

The cause was a bad strike position.It was attached by pushing downward.For this reason, it was confirmed that part of the strike was rubbing against the upper surface of the sickle deadbolt.

From the time I moved in, I felt like I was stuck and felt uncomfortable.Adjust the position of the strike by shifting it upwards, and then tighten it to prevent it from loosening.
