Funny this post should come up. I recently had issues locating the cap removal tool (magnet) shipped with the car from the previous owner. After some difficulty with ordering a replacement, which I had posted a few days ago, I was working on the oil change at a friend's shop when I asked if he had some magnets around. A 49 cent dollar store magnet popped every cap within a minute. Not trying to defeat the security of the system with this post, but the lug nut itself appears to be virtually infallable. Glad I did find that in the box of shipped items.
