WEST916.RA, Lost key, Unlocking the entrance door

"Lost key, Unlocking the entrance door"

It's not summer, but it's pretty hot. Route 16 is also quite crowded. After getting through the traffic, I finally arrived at the site.

When I checked the door, it was WEST916.RA.Especially since it is said that it does not have a smart lock etc., it was completed with normal thumbturn unlocking.
