KABA STAR NEO, malfunction check and cleaning repair

"The key no longer sticks."

When I checked at the site, it seemed that the phenomenon was gradually appearing.The cylinder seems to have deteriorated considerably, but it is a KABA STAR NEO with antique copper color, and it is the highest quality product.

It was used by the previous resident and has been used without replacement since the beginning of the move.

This may be due to aging such as dirt.Since the core cylinder cannot be disassembled, it will be thoroughly washed from the keyhole.

I continued to wash it for about 10 minutes with special oil and washing.Dirt comes out each time, but it has been improved as an operation.

In the future, I withdrew by suggesting that it would be necessary to replace it if similar symptoms appeared.

By the way, it came with a thumbturn cover, but you can unlock it normally with this type.
