Run the command: hf mf hardnested -t 36 -k FFFFFFFFFFFF Why: You attempt a known weak key. If the admin never changed the default transport key, you are done.

However, time is the enemy of all technology. Cards get demagnetized (in the logical sense), keys get lost, or sectors become corrupted. When a MIFARE Classic card stops working, it rarely means the data is gone forever. It usually means you lack the right . mifare classic card recovery tool
