ok guys,
since no one seemed to know about my previous post, how about a question on the key fob?
previously when i locked my doors with the fob, my hazard lights would flash. but just 2 days ago, they flashing of the hazard lights stopped. i can still lock/unlock my doors with the key fob, but the hazard lights don't come on anymore? note that when i push the hazard light button, it still works. just not with the fob anymore?
has anyone here experience something like this before? is my alarm not engaging anymore?
please help, thanks!
