Chinese Lock Mifare Classic Hotel Cards - not Vingcard

Hi,

A client is using hotel locks which are meant to use Mifare Classic cards, but the cards must be modified slightly as normal Mifare Classic cards don't work.  I presume this is to get them to keep purchasing cards from the same supplier.  Originally I thought they must be Vingcard initiated Mifare Classic cards, but this is not the case. 

The PM3 recognizes the cards as Mifare Classic and I have put a dump of one below.  I thought I'd post here just in case someone knows what is modified on the cards to get them to work with the door lock system.  Thanks

Is it using the same KeyA/B for last sectors on all cards?

Thanks. That was the answer.
