USHIN-SHOWA.IX DAC-II Unlocking the entrance door

"Lost key, Unlocking the entrance door request"

It was a request right after the end of business.It's a little late, but I'm heading to the site.I have a feeling that it will be canceled depending on the estimated amount.

It's dark when you arrive, and you need a light to work.After confirming the identity, it seems to be a major mechatronics company.I'm still a young engineer.

It was the USHIN-SHOWA.IX DAC-II knob lock.This type has a small thumbturn, so pinpoint unlocking is required.I adjusted the position and unlocked it in about 3 shots.
