The key fob will not unlock the vehicle remotely. I replaced batteries and it still does not work. I open the door the old fashioned way and turn the key , but the vehicle will not start. Electronics work ( radio, fan, all lights, etc.) and the lock cylinder turns as normal. However, the vehicle will not even attempt to start. Additionally the hazard lights will blink for a few minutes and then shut off even after key is removed. I assume this is some kind of built in 'warning' system. Any thoughts ? I called the local dealership and was advised this is not a common problem.
