Utility Spell

A target that is held shut by a mundane lock or that is stuck or barred becomes unlocked, unstuck, or unbarred. If the object has multiple locks, only one of them is unlocked.
If the target is affected by arcane lock the lock is suppressed for 10 minutes.
When you cast the spell, a loud knock, audible from as far away as 300 feet, emanates from the target object.
