I was walking down a row of Mopars at a car show, with my key fob in my pocket(2014 Chally). There was'nt much activity around these cars, just basically set and all lined up for the show. I'm almost certain that I heard chirping from several of the cars I was passing. This just didn't happen once, it happened several times. My key fob was in my pocket and maybe the walking movement, touched one of the buttons. What do you think, is this possible? thanks.
