WEST916.LDSP cylinder malfunction repair

"Difficult to insert and remove the key"

The scene was the top floor of a three-story apartment building.There is no canopy over the door, so the wind and rain hit the front door directly.

It looks like it has deteriorated with the muddy water of the rain. Since it is a WEST cylinder, there is no over-tightening unlike MIWA.

It was improved by disassembling and cleaning repair.It was pretty dirty.
