Comments

Only unlocked objects can be locked. If an object is already locked, it will stay locked with its original key. You must pass the same key to L_AnnUnlock to unlock the object(s).

An object must be unlocked in order to change its key in the automated mode.

Redact objects must be unlocked to be restored (unrealized). Refer to L_AnnUnrealize.
