I have a 2006 Accord that got a lot of things like this just right. First press: locks car and flashes hazards, with no sound. Second press within a couple of seconds: honks horn. If no flash and no sound: a door is open and it's refusing to lock. Most of the time I don't annoy anyone, but when I lose it in a car park I can get it to honk at me. Why is this so hard for other manufacturers?
