This is accomplished using an instrument designed specifically for key programming that harvests the code from the module and then burns it into the new key. Some vehicles will need the transponder to be completely reprogrammed, which is possible in certain instances with a J2534 interface, but generally requires removing the module and the EEPROM chip to reprogramme.
If the vehicle is equipped with an encrypted transmission, you'll require a specific software and key programming tools that are designed for dealers to program additional keys.
