This is basically for sending in an ID to Blizzard for retrieving locked accounts.
You will need to request this in my request thread at:

According to Verye Quote:
Lock - An account lock is when the account cannot be used until ID (and sometimes other info/things, such as money, or a picture of a credit card, or a notary, etc.) is sent to Blizzard. So, you send in ID to get it reopened. This makes it very different from a ban. In Blizzard terminology, lock does not mean ban. So, when I say lock, I mean an account that is in a state where it received an email asking for ID.
