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.
Oh, interesting. I thought most of them had been replaced with the newer versions. I didn't know about the replacement kit. Now that you mention it, I guess LPL might've said something about it in his video (which I didn't re-watch, oops!).
