Help for a vending machine

I am new there and was wondering how to get a key via reader attack i have a chameleon also as there is no battery inside the prox3 rdv4 if i am right when i put my normal badge wich had been activated previously via another reader if i put any other mifare classic 1k near the reader on the vending machine no lights light up but only when i put the activated one. This is weird how is it possible has i guess its not based on UID but maybe just a A key which read a specific sector so i try MF_detection on the chameon in order to act as a reader put my normal badge near the reader then i approch the chameleon in order to sniff some data
