So today I started the car (2014 Mazda6 GT) to warm it up then I exited (and closed door) to clear snow off while key fob in my pocket (no one inside car) and it locked the doors on its own. I couldn't unlock it with the fob and had to take out the actual key. I thought this was not possible in any Mazdas? This is my eighth Mazda and I never had this happened, as a matter of fact, whenever I tried locking the car while the engine running they all would not lock (tried it in the past on two CX-7s, one CX-9, one CX-5, one Tribute, another 2014 Mazda6 Touring w/MT, and a 2007 Mazda6 iGT). What gives?
