Hello, I have a issue with a PCF7953P from a BMW FEM key (its a OEM chip).
09 00 00 01 00 responds with --> 91 which means the key is locked
09 01 00 01 00 responds with --> 91
I've also tried to send 0a 00 00 00 00 which is erase and it indeed responds with 06 but after I try and send 09 00 00 01 00 again, it still responds with 91
Is there any MDI spec datasheet for these transponders? I suppose the commands got changed for these compared to the older pcf7953 or pcf7945
