What is not working? Does the engine crank and not start or nothing at all?

Some of those cars used a PIA chip in the key and only a dealer should disable that if that's the problem and you prove it's your car. T

those are the old URT systems if you have any controller,computer what you want to call it that is off the bus [not responding] then nothing will work right try holding your heat and off button at the same time this will run a self test off all systems and give you codes after you do that post the codes abd the theft systems are easy to by-pass on those
