Comments
Only objects locked with the same key can be unlocked. If the object is still locked or if not all objects have been unlocked (in case you tried to unlock more than one object), ERROR_ANN_LOCKED is returned.
An object must be unlocked in order to change that object in automated mode.
Redact objects must be unlocked to be restored (unrealized). Refer to L_AnnUnrealize.
