Just a quick comment: I'm not really mechnically-minded at all, and I simply did a youtube search for how to disconnect the hood latch sensor because, just as you reported, the mechanics won't do it for you (and the dealership certainly won't--they told me there's no way to "de-activate the alarm"). Only took me about five minutes and two or three good youtube videos to figure it out. Once it was disconnected, the van still locked. I left it disconnected for many months while I researched the problem and tried to capture the flickering with my cell phone to show my mechanic. Totally worth the five minutes to (temporarily) solve the alarm problem while you decide what to do next! I'd post a youtube link here, but I can't remember which videos I used.On a side note, I asked the Honda mechanic if he could disconnect the alarm so I could get back to work today and he said the since it's factory installed, it's impossible to disconnect it. I'll have to research how to do it myself if needed.
