can i feed reader with unauthenticated UID twice or more to sniff key?

can i feed an authenticated reader with an unauthenticated UID, at the same time sniff the trace, retry this procedure for 2 or 3 times,  to get the right key for this UID?

As my authenticated system have different keys for different card, and the reader can talk to every card offline, there must be something calculating keys by the UID, right?
