WEST SEKISUI Sha-Maison push-pull grip handle lock cylinder malfunction inspection

"I would like to have the lower key checked for malfunction"

When the key stopped sticking, it was disassembly cleaning of the lower cylinder WEST916-2200M (with stainless steel cap). Looking at the Google map photo, it looked like a push-pull grip handle lock that is often found in Sha Maison.

When I checked to see if it had a security thumbturn "Patante", I found a GOAL LX type normal thumbturn attached.

The type of engraving "D15" is used for the WEST lock case on the auxiliary lock side for normal Sha Maison.Cylinders and thumbturns are fixed with screws from the front side.

However, this time it was a GOAL LX pin fixation and a long screw fixation like LSP from the thumbturn side.Nothing is displayed on the front engraving.Probably because it is an OEM product for Sekisui House.
