Removing Locking Lugnuts - Without the Key
By DoubleZero4x4

This idea came from a Corvette owner:

You need to get a 12 point socket that barely fits and drive it on tightly, 4-5 decent wacks with a ball pean hammer will do the trick. You have to make sure the slots in the socket bite into the lug nut. Use a manual lug wrench - not a pneumatic tool to loosen the lug. Slow even torque is the ticket. When loose the lug will be stuck tightly in the socket. Place socket in a vice and drive ilug nut out with a drift punch and repeat three more times. Then throw the stupid locks away and get some standard lugs from the dealer in town.

I can tell you that it worked!!! I pounded on a 19mm socket and used a breaker bar to turn it slowly. Worked like a charm. Once the locking lugs were loose I simply pulled up and down slightly so that the socket would loosen up on the lug. Went to the stealership and picked up 4 news lug nuts and tossed the locking ones.
