I have a question about the PATS. My car still locks and unlocks with the key remote but you can now get in at anytime and start it. I used to have to start it in about 30 seconds after pushing the unlock button if I waited any longer I would have to unlock it again I like that feature. How do I get this back on their? Also I can push the trunk button on the key chain while the key is still in the ignition it wouldn't let me do this before WTF?
