@ifancho, Rather, you will not buy a card on aliexpress where you will be able to edit the CID. Only some Samsung cards had this option.
Besides, it is not about editing the CID number, but about securing the card itself in the chip. Read my previous post and what my friend @Boki_Srb wrote. Only buying a ready-made card makes sense in your case. Search ebay or some local retailer. You will find it for sure. Once you buy it, you put it in the car reader and go. You don't have to do anything else.
