it seems lately that when ever i walk through a metal detector in stores it always goes off. Obviously i don't steal items from stores so i am curious if it could be an article of clothing, jewlery, keys etc etc if any one knows feel free to answer

The detectors in stores are activated by special tags that are inside items. These tags respond to a radio signal that is generated by the sensor. When the item is placed on the part of the checkout that buzzes, there is a capacitor in the tag that gets magnetized (or demagnetized) , and the spacing of the metal changes, cancelling the effect of the capacitor.
If the detector is going off, then it means that you have some item with you that is responding to the RF field setup by the detector. It 's possible that some electronic item is responding, or perhaps you have one of these tags that wasn't properly magnetized. Some stores will let you through if the sensor alerts as long as you have a receipt. If they do this, and you carry the tag, it will go off when you go through.
A friend of mine had one such, and he used to put it in his shoe, and, wearing a tank-top, shorts and sneakers, have fun setting off the sensors.

The detectors in stores are not set off by metal but rather by chips embedded in price tags and packaging. chances are that you have an rfid creditcard (with a Radio Frequency Immiting Device chip in it) or a speedpass type thing as those tend to set them off a lot.

There is an RFID tag sewn into your clothing somewhere. Usually they are marked "Remove before wearing". Just find them and cut them out. No more alarms....

anything with a security tag on it.. check your personal items and see if something didn't get removed from your jacket or purse. even if it didn't come from that store it could still set it off

the sensors on clothes i think are magnetized so if ur wearing something magnetic it could probably be that also think of something u wear or carry whenever it goes off that could help too

I have seen some car alarm remotes set them off.
