I went to start my car and it won't even crank. This weird red key with a lock symbol chimes and means "Ignition Lock" or "Ignition Switch" after researching. The car recognizes both of my keys to lock/unlock the car. I have a push button start but doesn't work either. I replaced the ignition switch and starter relays and still nothing. I'm perplexed. Installed a new oem battery in the trunk that was not cheap at almost $400. Can anyone help give me an idea on what is wrong pleeeeeeeease? Thank you!
