CP certified product MIWA PS(DN).DAF+LSP Eccentric ginkgo type crime prevention thumbturndefect

"I can't turn the key, so I'd like to check it."

The target door had double MIWA CP certified PSDN.DAF. The defect symptom was confirmed with the upper cylinder.I think that the key is broken quite firmly.

This repair can be improved by disassembling and cleaning.

The cause was that the dust of wear due to aging obstructed the movement of the locking bar in the core.Remove it, reassemble it, and you're done.

Since it is a CP certified product, there are various traps.Assembly should be done carefully. (It's a little frustrating)

It was the lower thumbturn that caught my interest.Crime prevention thumbturn with different types of top and bottom is rare, isn't it?

This fan-shaped, shell-shaped, or ginkgo-shaped thumbturn is said to be 'eccentric', with a slight pull and turn.

I couldn't find the model number even if I looked it up.

Rather than saying "eccentricity", it seems that there is a clutch that can not be fixed to the rotating cam unless it is pulled a few millimeters.

It is the first time to touch the actual clutch type.

The clutch type has a note sticker attached to the thumbturn collar, so it can be identified by checking with a scope.

Since the clutch structure is different from the GOAL TM type, the unlocking method is also different.You don't need crab scissors.
