MIWA U9.LAMA entrance door key stuck

"Complete disassembly cleaning repair because CRC556 was used"

It seems that the client himself used CRC556 because he felt a sense of incongruity a while ago. He said it had improved then.

The client used CRC556 this time as well as last time, but it didn't improve, I heard.

I explained that "CRC556 is something that should not be done in the world of keys" and gained understanding.

First of all, after removing the key, we will perform a complete disassembly and cleaning. Remove oil with parts cleaner and lubricate. It was then reassembled and completed.
