Within the last couple of weeks my security system light is on when I get into the car, it wasn't always, but now it is. Also when I use the keyless entry the horn honks and the doors open but no lights flashing. What could be causing this. Is it an error in the computers that I can just reset it by disconnecting the battery? If anyone has figured this out could you let me know.
