really sorry to hear that, i hate bandits. that guy will get what's coming to him i'm sure. if you have a car key that has some electronic parts and are worried about water getting into it, just use 2-3 ziplock bags before you stuff it in your pocket/wetsuit. works for me.
hiding your key works too but there's always a chance that someone saw you stuffing it underneath a rock or whatever and you would never know until your stuff was gone. maybe your whole car too if you get robbed by a real asshole. be careful, i hate hearing stories like this.
