When someone sells a key set, does it mean 3x3 or just 1 of each?

Thanks for your time!

technically a keyset is 1 of each, people say "3 keysets" or "3x3" for a full set.

While “Keyset” should* mean 1h1t1d keys- and “3x3” should mean 9 keys, I’ve seen them used interchangeably by some. Usually just pay attention to the price. One is 3x more than the other usually. Hope this helps

Clear as mud! Thanks haha
