are these keys?

Hello so this card is a mifare desfire ev1. MF3ICD41

Heres the snippet I dont know what to make of in Nxp taginfo in the memory dump.

 • File ID 0x08: Standard data, 32 bytes    
◦ Communication: plain   
 ◦ Read key: free access (0x0E)   
 ◦ Write key: blocked (0x0F)    
◦ Read/Write key: master key (0x00)  
  ◦ Change key: master key (0x00)

Contents:
[0000] 1F 00 00 00 81 00 00 80 |␟␀␀␀·␀␀·|
[0008] 00 00 03 86 46 60 05 DA |␀␀␃·F`␅·|
[0010] A0 00 00 00 00 00 00 00 |·␀␀␀␀␀␀␀|
[0018] 00 00 00 00 00 00 00 00 |␀␀␀␀␀␀␀␀|

if these are keys how do I use them? from my understanding this card uses 3DES and shouldnt it be 32 bits? so sector  0000 and 0008?
