I have a 2007 Ford Edge. It will not start 80% of the time and the anti theft light flashes rapidly. The next time it might start right up but if it does then the lights will come on and then turn off. The radio was playing and now it will not turn on at all. My air would not turn on and then finally it kicks on. My battery is good, bought a new transponder, locksmith said keys are still good. What is the problem?
