"The key is difficult to turn."

It seems that he had been concerned about the defect for a while, but finally decided to call a locksmith.

Although it is a detached property, I was told that there is a rental contract.PLENUS has an electric lock, but it seems to use a key.

I decided to disassemble the cylinder unit and thoroughly clean it.No defects were found in the motor unit, so I completed reassembling it.
