MIWA U9.DA, Cylinder replacement due to lost key

"I don't have a single key, so I want to change the key."

It was a phone call from a client who wanted to exchange because he didn't have a single key.It's like kindergarten.

Even if I could lock it from the inside, it seemed that I never locked it from the outside.

It seems that I have decided to review this time and replace the key.It seemed like a budget issue.

There were two places, upper and lower, but due to budget reasons, only one place was replaced.
