Correct - which is why I wouldn't spec Advanced Key on my S3!
As to an effective way of stopping access to the port, I've sorted that one out - a friend of mine showed me how he'd done this in his M3 after his first one was stolen by some **** using a laptop and before anyone asks, I'm not saying how you do that on an open forum! The second I get my S3 home from the dealer I will sort that one out!
I had a car stolen a few years ago where they broke into the house and stole the keys that were in coat, hanging off the stairs- they removed the car flap and then my back door to get in would you believe... if I'd disturbed them ****ing right I would have had a go! I'm ex Army and know how to defend myself, so good luck if anyone want to wave a knife at me. After that experience I fitted a house alarm, better security lighting and upgraded locks on the doors. The keys now stay upstairs with me and I never, never leave the house without them, spares are not kept at the same property ... don't be worried about the stories you her of people being threatened at knifepoint, it's very rare that they will risk any kind of contact with you as one speck of DNA left behind and they're going to get caught - they'd have to be pretty desperate or stupid to risk it, most are looking for an easy target and most people make it easy - been there, learnt the hard way.
