WEST pin cylinder G7510 ACT lock, Lost key, Unlocking the entrance door

"Lost key, Unlocking the entrance door"

It looks like an apartment near the beach. He said he lost his key this time, but it seems like there were various defects. They explained a lot of things to me, but I needed to check it out on site, so I decided to head there anyway.

This is a pin cylinder rim lock G7510ACT lock made by WEST. Since it is a knurled thumbturn, it was completed with normal thumbturn unlocking.
