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 that object in automated mode.
Redact objects must be unlocked to be restored (unrealized). Refer to L_AnnUnrealize.
