Help with iClass DL cards from Red Team Tools

EDIT: SOLVED! In typical fashion, not long after finally deciding to make this post did I get this figured out and working. I owe that to this post here: … rd/14180/2

My issue was not updating keys, which the above post explains how to do.


Hi All,

I am trying to learn more about working with proxmark and iClass cards. I purchased some Blank iClass cards from Red Team tools (, but can't get my readers to recognize them (R90 and various multi-class readers). I am able to use the proxmark to write data to the card and have tried changing the configuration mode from "[+]     mode......... Personalization (programmable)" to "[+]     mode......... Application (locked)" after writing the desired data to block 7, but the readers still show now indication of reading/recognizing the card.

The Red Team Tools product description says:

"This is an non-programmed, iCLASS 2K credential in an UNPERSONALIZED STATE.

Using this credential will require an understanding of personalization procedures or tools for the PicoPass chip."

I have a feeling I am missing a step or just not following the correct personalization procedures for the card. I also attempted to read the card using the software from, but the result was "Error: Authentication failed". If anyone could help shed some light on what I may be missing (either directly or to documentation I may have missed) I would greatly appreciate it!!

Here is the result of the hf iclass info command on a blank iClass DL card that I have not made any changes to:
