LOL, I used to do that too when I first got my Civic, did it twice, no more. I just have this mindless routine now, get in car, put on seatbelt, get out of car, check to turn off light (even if it's not on). The buzzer is pretty simple mod though, they also sell 'kits' on eBay, but I don't know about paying that much $ for radio shack parts you can do yourself.
