MIWA PR.LSP + ginkgo type eccentric crime prevention thumbturn Unlocking the entrance door

"Lost key, Unlocking the entrance door"

It was a completely different case from what you had reported in advance. The client may not be aware of the key to the front door. Even though you operate it every day, if you don't pay attention to it, it's normal to hardly remember it.

At the hearing, it looked like a switch-type B5 security thumbturn. I also checked the photos.

Well, when I started working, it was "Ginkgo type eccentric crime prevention thumbturn". It is a type that rotates while pulling a little. I usually recommend using search unlocking, but this time I proceeded while checking the CCD.

Then I was able to unlock it. I was surprised that I was able to unlock it with the tip jig for B5, but it was not as robust as TM type thumbturn made by GOAL.
