Welcome to this forum! I've renamed your thread, and moved it into the stock 2002-2005 section.

if you only have one key, there is no way of programming it yourself. Also the original key is still programmed in the PATS module so it has to go to a dealer either way to have the PATS reset and have a minimum of two new keys programmed. The column just reads the chip in the key and has nothing to do with security. It is all located in the PATS module

can walmart do it they have a machine thats reads the key and programs the blanks. or does something else have to be done to get the key to work after walmart programs it. i have also heard that you can a regular key made and use it as long as you have the right transponder taped to it. dont know how true that is. can anyone confirm that?
