U9.THMSP-SA Unlocking the entrance door and cylinder replacement due to malfunction of key

"Unlocking the front door"

I was asked to open the door, but when I asked him carefully, he said that the key wouldn't stick all the way in.

Unlocking a detached house is often broken, but this time it seems to be improved by replacement.

The cylinder is an H248 disc type.I don't have a spare key, so I decided to replace it.

MIWA U.THMSP, thumb-latch tablet. We have the SA color in stock, so we will replace it according to the procedure.

Since it was a relatively new thumb-latch lock, the current replacement cylinder was able to be assembled neatly.

When I lightly brushed the pedestal of the decorative part, the dirt was removed more and more.It has become quite beautiful.
