If you mean the fender and deck lid emblems, the only thing that can help you is a security guard. But if they're taking the grill emblem, there are many kits out there that give you the emblem plus special security screws that come with a key. Of course if someone worked hard enough they could get them off too, but with an alarm it might give you more time to get outside and kick some ass.
