Slightly different process. The TSA keys aren't "master keys" in the normal locksmithing sense; they typically go into a separate lock that's only used for that key. For instance, the lock pictured in the article is normally used as a combination lock, not a key lock.

Yep. The "security" is that compromised; leaked photographs or no.
