I was planning on replacing the brake pads on my sister-in-laws 2005 Chevy Blazer. The wheels have a locking lug nut - internal 6 slot pattern - and she does not have the lug nut key?

Shall I just get divorced and walk away or does someone have a less painful solution?

 

-you can buy a wheel lock removal kit
-the splined lug nuts are fairly common...autoparts store may be able to order a common key for that type
-you can have a shop remove the wheel locks

 

I have removed them before with a hammer and chisel. Hitting the lug nut in the direction that would remove it. I have also used a big vise grip. These sometimes work but it would be a lot easier to order a common key as stated above.
