MIWA WEST916.LAMA, additional door cushion repair due to locking failure

"It became more common for me to not be able to lock the lock."

It seems that recently it has become difficult to lock the door from both the outside and the inside.

There may be a defect in the lock case, but I hope there are no major problems. When I arrived and checked it, I found that there were times when it did not engage either from the thumbturn side or the cylinder side. There seems to be no problem with the lock case. It seems that the relative position with the strike is off.

There seems to be no problem with the distortion of the door and outer frame. When I looked at the door more carefully, I found that it worked normally when I pulled it closed, which turned out to be an abnormality in the door packing. To solve this problem, an additional door cushion was installed. By the way, the strike was recessed and not adjustable.
