..very sorry to hear what happen to you bro..really..i cant do much about whole thing, but i can share what I do...when im approaching my vehicle, i never ever approach it directly..instead, i just take short walk around, in order to observe surrounding vehicles FROM BEHIND..because, if you looking nearby car from front side, you cant see if someone is bent down, however, from behind, you see entire interrior and eventually someone sits in there..also, such move (lil walkie around), doesnt pointing what vehicle is yours therefore, potential thiefs have no clue about it, unless they know it in advance (what is entirely different story), but even in that case, observing vehicles around, on way i said, is very very good headstart, and radius of observation should be based on how quickly you can unlock, sit, start engine and make a move, without been approached from further spot you have observed..thats what I do, appart from clerly exposed baseball batt handle , visible from my backback...also, i suggest to everyone to install some custom made switches, needed to be turned on before car key takes place in startup process, on that way even when you handle keys over to thief, you can run away, until he realize that hes going nowhere with car (not that he cant bypass it, its just...no time for it..)..
