He mentions the mech was changed in 2011, mentions there’s a probably little used retrofit and at the end of the video he comments that there are likely many compromised ones still out there.
Which is pretty expected if you've seen how buildings are maintained in general. I haven’t encountered a lock that doesn’t have this vulnerability in any 20th century post-war nyc building.
From his comments, I don't believe the vulnerable ones are still out there. But, maybe they are.
