Wheel lock problem
 

The lock key groove broke in the wheel lug. I can't get it out. I tried drilling it out of the lug nut but the drill bit keeps on braking. Has anyone experience this kind of problem?? If so, how did you get the lock nut out with a lock key?? TIA, Sam

You need to hammer on a socket thats just slightly bigger than the lock, or heat the socket so it expands, and then hammer it on.

Drive it over to a tire shop. They'll have something like this:

SK 920 2 Piece 1/2-Inch Drive 3/4-Inch / 13/16-Inch and 7/8-Inch / 15/16-Inch Turbo Socket Wheel Removal Set - Wheel Lock Removal Tool - Amazon.com

This is the same exact tool they used with no luck. They said that the spinning ring on the lock nut is stopping it from removing the nut. How do I remove the ring from the nut? TIA, Sam

Put an add on Craigslist offering anyone $50 that can removed the wheel lock.

I sure there are some enterprising young men in your area that have a bit of experience removing these wheel locks!

i had an issue one of the heads broke off and the other one broke the key so same situation as you sounds like and i had a shop drill it out took about an hour

Drill may be breaking with too much force or speed, try a machine shop or automotive shop.
