No Keyring

I believe that the first one that can be obtained is https://classic.wowhead.com/item=5020/kolkar-booty-key#dropped-by

There's also been some people who say that the Keyring doesn't exist, but the Benedict's Key and Kolkar Booty Key (some of the lowest level keys you'll find) do NOT go into the keyring, which is where the whole "keyring doesn't exist proof" has come from over the last few months

I believe it doesn’t go into the key ring because it’s a one use item. The rest of the keys and to scholo for example is infinite uses that’s why they are in the keychain but Kolkar key isn’t..

.. babyyyyy
