Review on McGard 25354 Chrome Black Thread by Terry Paige

I have been using these locks for many years but this time they are cheap quality! A lock nut is damaged because the key broke during installation and now part of the key is wedged in the lock nut! So far it's still stuck in there and I have no idea how to remove it. I tried to break the metal out of the grooves but it's hard! I hope I just don't have a flat tire, but somehow I have to fix it!
