Inherited '82 Lincoln Continental.Locking lug nut. How to get replacement key?

Thamks so much for your kind interest. One of my neighbors volunteered to get it off for me. He succeeded after considerable effort. Now, I don't know how to remove my question from this website. Thanks for your reply.

I don't know if you can remove it,i never ask a question on here yet. Other people will see that it was answered and also see your reply that you got them off.
