@dearlucid I am not sure if you have figured this out yet or not, but I was successful in cloning my elite card, you just need to copy over the elite key to block 3 of the new card.
I followed these two guides specifically:
Need help cloning HID iClass Legacy - Support - Dangerous Things Forum
Clone my apartment entrance card. The management office of my apartment… | by lff l | Medium
These are the specific steps i performed to copy over the iclass elite card to a non elite card/fob.
On the card to be copied from:
- hf iclass chk -f iclass_elite_keys.dic --elite #the output mentioned that it saved the key to position 4 of the managed keys file, hence --ki 4 below.
- hf iclass dump --ki 4 --elite
On the card to be copied to:
- hf iclass chk -f iclass_default_keys.dic #as this is a non elite card, you can use the default keys
- hf iclass restore -f hf-iclass-XXXXXXXXXXXXXXXX-dump.bin --first 6 --last 18 --ki 0
- hf iclass calcnewkey --oki 0 --nki 4 --elite #two things to note: 1) the --nki 4 corresponds to the --ki 4 from earlier; 2) you will get a Xor Div key output here for the next step
- hf iclass wrbl --blk 3 -d [XOR KEY] --ki 0 #use the Xor div key, input without brackets.
Let me know if you need any help
