Answer
You will really need to remove that remote start.  It sounds as if the module is faulty and keeping ignition voltage to the ignition switch when it shouldn't.  This is a common issue after replacing the battery as it will lock up the remote start module.  Also check to see if you have power at the starter when this happens.  If you have power and won't crank it's a faulty starter.  if you don't have power, check the relay, if still no power at the relay its gonna be that remote start
