If they're the plastic ones, just gouge them out with a screwdriver. That's what I did with mine, or at least the one remaining one. The other was destroyed when I tried to drive over a recycling container that the collectors had thoughtfully dumped right in front of my car where I woudln't see it.
If they're the metal ones, then go with what's already been said. You need to start with a bit that will happily sit in the dimple in the top of the rivet and then work your way up from there. Just don't apply any more force than is necessary to keep the bit in contact with the rivet.
Even an oversized bit shouldn't be a problem. You'll know when you've drilled far enough because the rivet head will start spinning round on the end of the bit. You'll be left with the body of the rivet sticking out, but you should be able to push that through.
