all Key A and Key B are FFFFFFFFFFFF of hotel key card

I have some hotel key cards of "the icon" brand from China. It is mifare classic 1k, but I cannot crack information. all Key A and Key B are FFFFFFFFFFFF. When I use Key A or Key B, they cannot read information in some bock. I think it must has extra security layer. Right? How to do later? Please advise me.

Re: all Key A and Key B are FFFFFFFFFFFF of hotel key card

Yes, I tried manually on block, which has information such as sector2. It doesn't work.
