GOAL D9.TXK(QDD866)+TDD mountain thumbturnUnlocking the entrance door

"Lost key, Unlocking the entrance door"

It was a request to unlock late in the evening. It was completely dark when we arrived at dusk.

It was a two-lock front door. Judging from the door handle, I thought it would be the QDJ-2 type.

I tried normal thumbturn unlocking, but both shots missed. Feeling a sense of incongruity, I checked it with a camera, and it was a slightly smaller mountain-shaped (Mt. Fuji-shaped) thumbturn. Depending on the position and angle where the tension is applied with the tool, it will pop off smoothly.

It's no good when it's not good even if it's slippery.

Therefore, adjust the angle to apply tension vertically and concentrate the position on the root. This unlocked it.

When I checked after unlocking, the handle was for QDJ-695 made by USHIN-SHOWA, but it was TXK (QDD-866) + TDD made by GOAL like thumbturn. I don't see this combination very often. A rare combination.

You can't tell if it's QDJ-695 or QDD-866 just by looking at the handle and cylinder from the outside.
