Knock
Choose an object that you can see within range. The object can be a door, a box, a chest, a set of manacles, a padlock, or another object that contains a mundane or magical means that prevents access. 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 held shut by Arcane Lock, that spell is suppressed for 10 minutes, during which time the target can be opened and closed.
When you cast the spell, a loud knock, audible up to 300 feet away, emanates from the target.
Knock 5e 2024 vs. 2014 edition differences
The 2024 version clarifies that Arcane Lock is a spell, not a lock type, and states "opened and closed" instead of "opened and shut," but otherwise, the mechanical effects—unlocking mundane or magical locks, suppression of Arcane Lock for 10 minutes, and audible knock up to 300 feet—are essentially the same.
