Lock a forum:
AdminCP => Forums & Moderators => Forum Manager => Create a new forum or edit an old one => Forum is Open => No

To display the lock icon:
AdminCP => vBulletin Options => vBulletin Options => Forum Listings Display Options => Show Lock Icons to Users => Yes

This is a question about vBulletin in general, not about modding the vB code. So this is more a question for vB.com
