93 Prizm lug nuts/wrench

Hello,
I just purchased a 93 Geo Prizm LSI. Upon attempting to remove a wheel to install a full spare with better tread, I noticed the following:

1) The head of the lug wrench does not quite fit into the holes where the lug nuts are.

2) There are two lug nuts (one on each rear wheel) that are not hex... rather they have a flower-like indentation pattern. I have no idea how to remove these.

Any thoughts? (Mostly on #2... I think I will just have to obtain a different lug wrench for #1).

Thanks!

#2 is some sort of wheel lock. You'll have to drill them out, but before you do, try searching the car for the key (look in the glovebox or under the mats)
