I have a 2002 Camaro v6 35th anniversary and it only works with the remote start! And sometimes it takes a couple tried before it turns on. I replaced the car battery (got it tested said it was bad) Any idea what that could be? Couple options were thinking is the VATS system and the keys, the ignition cylinder, some faulty wires or I read somewhere primary and secondary battery? Not sure what that is need help!!
