I have a brand new 2005 Forester. The alarm should beep and flash the hazard lights once when I push the "lock" button on the key fob and should beep and flash the hazard lights twice when I push the "unlock" button on the key fob. It worked fine for one week and then the hazard lights stopped flashing. Now I only get a beep. The doors lock and unlock but I don't know if the alarm is being set. Has anyone had an issue with the hazard lights not flashing when using the key fob and how to fix this issue? Any suggestions are greatly appreciated. Thanks
