The passive anti theft system (PATS) needs reprogrammed to identify the new key. This requires a scan tool with the programming installed to enter the PATS system, erase ignition key codes, program ignition key codes, and so on. The only way to program the system is this way or you need to have the original programmed key available.
I'm sorry for the bad news. Please let me know if you have other questions.
