MIWA LB.08LEF, Lost key, Unlocking the entrance door

"Lost key, Unlocking the entrance door"

It was a late evening request. It seems like he dropped his keys on his way home from work, or the request came from outside. We decided to specify a time and meet at the site.

Wait for the apartment residents to pass through the auto-locked entrance for a while. It seemed that the management company had already closed for business, so he couldn't seem to get the special code for the entrance. It wasn't long before the client tailgated through the entrance and arrived at the front door.

What looks like OPNUS is a MIWA LB cylinder. It's an LSP type cylinder, so it's usually a thumbturn.

I was able to unlock it shortly after starting work.
