I have a question? I am new to auto programming and I'm confused about something. I am trying to add a second FOBIX to a 2016 RAM truck using a IM508. I can pull the pin code with no problem, I click add a key, then it tells me to put a programmed key in the ignition, then it tells me to erase keys. Is this correct when adding a second FOBIX? Should I be starting with the key that's already programmed or the new unprogramed FOBIX? If I start with the programmed key and click erase key am I going to mess up the working key? Again, I'm new to this and any help understandings this procedure would be greatly appericated.
