    As a matter of general principle, the second noun in a combination like 'key card' describes the nature of the object. Thus, a key card is a card that works/look/functions, etc. as a key, whereas a 'card key' would be a key that works/look/functions, etc. as a card. In your case, I have seen and heard of cards that function as keys (e.g. in hotels) but I have no idea what a 'card key' would be.

    Hi olga69,

    Please give us some context for these terms - where did you come across them? We need a complete sentence to show us how you saw the word used or how you are planning to use it.

    Alternatively, a 'card key' might be some key (possibly a code) that unlocks a card, but, as I said, I cannot know what exactly it is out of context...
