The Passive anti theft is tied into the PCM and cannot be disabled, I have attached a technical service bulletin that would need to be reviewed upon diagnosis of this problem that you are having. You have a problem with the system that will require repair before the vehicle will be allowed to start.
Unfortunately, yes because of the need of special diagnostic equipment you will not be able to do any thing on this concern yourself, I attached the document so that you might have an understanding of the complexity of this system for informational purposes only.
