It's a different door with different keys, is a good analogy, ...
Well, sort of ...
It's a different, secret, door that initially takes the same key as the main door ... but when you discover someone has been getting in and you change the lock on the main door the intruder can still get in through the secret door (either because the old key still fits or because it's been left ajar -- that part's not clear from the article) ... and as the door is secret you can't find it to nail it shut.
