Laser 3D scanner is used in the movie to scan a key: technically possible?
There have been instances where people have replicated a key from a photograph of a key. A multi-minute scan of a key seems like overkill, but that appears to be a very large key so maybe so.
Is it possible? Yes.
Is it exaggerated? Probably much simpler than is portrayed.
Is it fiction? As portrayed, yes. Practically, no.
