Re: Need help to determine what went to wrong,cloned fob can't open door

unclear if you dumped the card with a complete key file.
The system could have detection against Gen1a tags.  What type of system is it?

Ok,  so dump is good.
and now try simulate with your pm3,   afterwards read the trace list and see if the reader has some funky stuff going on.

Re: Need help to determine what went to wrong,cloned fob can't open door

What did you do to get that trace?

Did you do a eload/sim against reader?

Re: Need help to determine what went to wrong,cloned fob can't open door

Hi,Iceman,sorry for the delaying answer your question,that was not from pm3 eload/sim,got that from cmd,hf list 14a,but I have read other threads on forum,and I noticed that sak values been changed from 08 to 88,so I've changed sak value to 08 and tested on reader,no luck,at this point,like you mentioned earlier,system might have detected gen1 card,so I will order some gen2 cards and will test and let you know if that is gonna resolve my issue with cloning mf 1k fobs,thanks for your help any how...
