write keys to mifare card

Hey, the question "Is it possible to write complicated keys to mifare cards to make them more secure ? for a blank mifare for example..." if yes, can the pm3 do it ? and any suggestions ??!
thanks to everyone can help.

It doesnt matter the "randomness" or complexity of the keys, as long as they're not any "sample" key. So if all the keys for the card (A & B) are not trivial, there is no difference in the security you can have.

So you mean that I just have to rewrite the blank blocks with a random keys and it will do the job ?

and yeah, how can I write sensitive data with these random keys to make the data not appearing in plain text ?
any ideas ?
