Yale 5000-series security lock: Yale 5000 innards

This is a walk-through of the "high-security" secondary locking mechanism available on some Yale models. See also pages 16 and 20 of http://stuff.mit.edu/afs/sipb/user/jhawk/cyl_keys.pdf for diagrams.

Cheers,

I have never seen that type of secondary locking feature good find. I am hit or miss on eBay but lately knave gotten some nice stuff. Taking it apart will help you a great deal with picking it getting locks open that have stumped me in the past always feels great .
