On a 2004 Accord EX. I pulled up to the post office, got out to stuff some mail into the mailbox. Left all the windows open, doors unlocked, since I was never more than fifteen feet away. Got back to the car and it had locked itself, open windows and all. So I reached in and unlocked the drivers door. Alarm turns on! Once I figured out it was mine, and I had set it going, I was embarrassed. How to turn it off? Guess what, pressing the panic button on the magic key doesn't help. Putting the key into the door and turning it seemed to do the trick. I really must read the manual one of these days. And probably turn off some of these zippy tricks, but at least to be aware of them. J.
