opens

While the key fob is in my pants pocket, when I bend down or cross my legs, sometimes the panic alarm will sound or the trunk will open. Evidently my leg is accidentally pushing the key fob buttons. Is there something that I can do to prevent that from happening such as buying a certain key fob...

Did any have this problem. Trunk opens with out key fob. I just touch the trunk rubber with the key fob in the house and the trunk opens. 2012 4.6, with less than 2,400 miles. Marty
