Change cylinder to TOSTEM PSDN.D5GZ3021(MCY475)

"Lost key and a student card, Unlocking the entrance door"

I had a request late in the evening. I heard client's son dropped it on the way home. It was the content that they want to exchange today.

There was a USHIN-SHOWA Z-2A2-DHYD, 1K2L with a WX cylinder. Since it is a DT40mm insulated door specification, let's replace it with a so-called TOSTEM egg type.

QDJ-695/QDJ-696 is equipped as a lock case. I changed to PSDN.D5GZ3021 (MCY475).
