Lost key, Unlocking the entrance door

"Unlocking the entrance door of a dormitory for employees of a major electronics manufacturer"

I think the man called the second company. The first company said that they couldn't unlock it because they didn't have a door scope, so they couldn't help it.

When I checked the door, it was a MIWA H248 type disc tumbler cylinder and it was an LSP type.When I saw this, I was surprised at how well it was done.When I asked the client, it was a company that offers a famous key rush service.

I don't know why the workers there couldn't do it. There are several unlocking methods, such as bypass unlocking, but usually unlocking is completed by picking.
