"Sometimes it's hard to turn the key"

There was a request to check it because the key sticks in but it is sometimes difficult to turn.

I thought it was due to dirt due to deterioration over time, but I didn't feel any discomfort when the door was open, but it was confirmed that the cylinder was loose in this type, so I removed the thumbturn and confirmed it. Did.

It was a little loose, so I retightened it and cleaned and lubricated the lock case.

There was almost no discomfort when the door was closed, but there was a sense of discomfort when the door was pushed a little.

There seems to be deadbolt and strike interference. It seems that the rubber door gasket around the door is crushed due to deterioration. It improved when I installed additional door cushions.
