What? No longer in use? Those things are still widely in use in many mid century and older education and healthcare buildings around NYC.

I assume this specific model is no longer in use. Sorry, I should've been more clear.

From his comments, I don't believe the vulnerable ones are still out there. But, maybe they are.

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.

The lock is still in use but the vulnerability has been fixed in newer models and older models can be fixed by a part kit.

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!).

Thanks! Very informative!

Yes they are still around!
