Unlocking the entrance door due to USHIN-SHOWA WX cylinder malfunction

"Unlocking the entrance door due to malfunction of cylinder with key"

It was a newly built property less than a year old. It's not listed on GoogleMap either.I decided to go to the area near the site and look for it, but I was able to meet the client with the first case that seemed like it.If there was no client, there would be no display of the property name, so it would have been difficult to judge.

Now, looking at the site, it was USHIN-SHOWA TOSTEM (LIXIL specification) with two identical cylinders).The bottom side seems fine.

From the shape of the handle, you can tell that the lock case is "QDJ695 type", so in the worst case, the parts inside the case may be defective.This has been addressed as cylinder breaking and unlocking in a similar defect case.

I stab the WX key in the upper cylinder, but it felt like it wasn't mechanically pierced all the way. Leave about 5 mm and do not pierce all the way.

First of all, it is spray cleaning, but since it is a new building, deterioration over time cannot be considered.

The defect status does not change, so change to normal unlock.

The position of the scope was near the top, so the door guard got in the way, but I was able to unlock it with the second shot.

Since we have decided to give priority to replacement, we will not perform a teardown investigation.At a later date, I presented a new replacement request to the owner and completed it.

Some of the tumblers are not working properly due to spring defect.This kind of phenomenon is rare.
