MIWA U9.LA cleaning repair due to cylinder malfunction

"I feel a sense of incongruity when opening the key"

I received a call late in the evening. It seems that the client have been worried about it for a long time, but when he came home today and unlocked it, the symptoms were getting worse.

When checking at the site, there was a strange feeling that the cylinder was caught. This type of symptom is common.

It wasn't enough to disassemble, so I was able to improve it with spray cleaning and lubrication from the keyhole.
