Hey, I'm Sandy and I work with Granite Auto Parts in Granite Quarry NC. I'm having trouble with an Elantra. I need to get the PIN for the Smart Key fob. I've replaced the PCM due to a rom failure. I have the VIN for both the new PCM and the vehicle. I have the equipment to program the key but not the pin. I also have a question if there is a trick to write a new VIN when one already is stored in the PCM. I'm working on limited resources here.
