Getting locks off of wire wheels . . . .

Although it has these goddam locking lug nuts on it, and I don't have a key. What's the best way to get these off? I don't want to damage the wheels, but there are spokes everywhere, and it looks like a real bitch job. Luckily my caddy dealer had a set of regular lugnuts that will work, they just gave them to me

I know they make a socket specifically for rounded off nuts that looks kind of like the inside of a rifle barrel.
to get the lock out of the socket when its stuck hit it wit a hammer on the sidein the middle of both then yor done lol
