I wear a large silver belt buckel, and have a keyring full of keys I use everyday. I years past, at the security chk pt's, I would just take my buckel off, keys, glasses, a big hand full of pocket change, and watch in hand and still would set the alarm off. They would then take me aside, use the wand over me an then let me go. Now, I plan on wearing a plan belt, taking only a car/house key, no pocket change, wear my 10es, and I'll probably will still set the alarm off!! Oh well!! I feel for those folks that have steel pins/rods implanted in their bodies at this time.
