Buy a crappy socket or find a spare socket that you don’t want anymore. Find one that is just small enough that it won’t fit over the outside of the lock nut. Take a hammer and pound it over anyways. Bust out the ratchet and remove. The lock not then becomes not re-usable, or at least… It’s a bitch to get the socket off the lock nut. I did that when I had a single lock nut on a car I bought and no key. Worked perfectly and took about 45 seconds extra time.
