My car was stolen last friday. I am still so mad for what has happened.

Fortunately I never leave my empeg in my car, so, while two bags of clothes, a laptop, and other stuff are gone together with my Volkswagen Polo, my empeg is still with me.
I however lost two amplifiers, 6 speakers, 1 subwoofer, the empeg sled (fortunately I have a spare one) and two empeg remote controls (a Rio and a kenwood).
I hope I'll be able to find those two somewhere here, if there's anybody who wants to sell.
Worse than that, I lost my original empeg radio module, and will have to buy a new one And, to make things worse, I also lost Mark's Docking Station which I was bringing home and was in the trunk.

You may be asking how come I left all that stuff in my car. Well, I of course never leave anything in my far, generally speaking. In this case, I was going out for the weekend and had just stopped home, in a quiet and nice neighborhood in Rome where usually nothing happens, to get few last things. I staid at home for few minutes. I'd say hald an hour at most. Enough for the thief to open my locked car, start the engine, and leave. 3:00pm, people walking by, cars passing by. No sound of alarm. No truck can make it into such a relatively small street with cars parked on both sides.

Now, besides trying to recover, my question is: how does the Volkswagen key-code work? How easy is it to crack it somehow and have some sort of facke key which not only opens the car without having the alrm to go off (whcih I could also expect), but also starts the engine seaminglessly? That must be what has happened because the thief must have looked like a regular guy, like the owner of the car.

I am still shocked and quite suspicious about the anti-theft systems in VWs... Does anybody have an idea of how is something like this possible?
