At this time the only tool that claims to unlock this key is hexprog, but I tried and it failed.

Do you read PCF7944 via RFID or read via wire interface? Originally Posted by bmwspec

Just tried it out with Hitag2 v3.1 tool. Indeed I am able to read out the Remote data! So at least I would be able to program that to CAS3 in order to make Remote work.
But how is it possible to get Hitag2 crypto (ISK Hi Lo + Psw) if you have only the key (not the CAS belonging to the key)?
