What you DO NOT say next is 4NT. If partner answered 1 Key-Card you would not know what to do. If he has a red Ace you can make slam, but if his one Key-Card were the ♣A you couldn't.
Instead you make a control-showing bid of 4♣, promising first round control. Partner obliges you by bidding 4.

Partner's bidding is like the Sherlock Holmes tale Silver Blaze, about the dog that didn't bark. Partner's bid shows that he DOES have the A, but equally important it shows that he DOES NOT have the A. So you know you don't have a loser but do have a loser. You bid 6♠.
