By ‘key’, I assume you mean the key signature (I.e. what set of notes the piece or song uses) as opposed to a piano key or something. If so, there is no concept of higher or lower for key signatures. A key signature just refers to a different set of notes. It’s like asking which numbers are higher – odd numbers or even numbers.
