WARNING: I tried to look on the web for a solution of how to take the lug nut off, I came across some advices and that was a bad idea to try one of them …

Some people on some forums say - get a socket of a size a tad smaller than a diameter of your lug nut and hummer it in until the socket sits tight, then use a wrench to loosen the broken nut - BIG MISTAKE.

I tried that – 1st it didn’t work for me (maybe worked for someone else), second I damaged my wheel bearing and it cost me close t0 $200 CAD to replace it … (the rear HUB replacement procedure I published in another article on this website).

Turned out that the McGard key broke when I tried to loosen lug nut on one of the wheels stud. That’s a very nasty situation. As I discovered lately the Security Lock lug nut corroded into a steel wheel whole and got stuck badly so the lock Key couldn’t sustain the pressure and broke.

On the picture above it can be seen clearly the crack on the wheel lock Key internal pattern.

And here is the lug nut itself after removing (the one to the right is the broken one). I had to take off all the other 3 wheel locks as I don’t have the lock no more and there is no way I could take a wheel off on a road might I get a flat tire.

The cone shaped tip broke-off after I force-turned it. Actually it stayed on the wheel lug and I had to use cold chisel to break it in pieces and take it out.

Second lug nut had a visible crack as well so I suspect it was nearly to a break point as well.

Here how you remove a security lock lug nut without the Key. All that you have to get is to invest into a magic tool kit called – “Hubcap and wheel lock removal kit”. See pictures below…

All you have to do is hammer the small socket (third from the left on the picture above) on top of the wheel lug nut using the applicator and a hammer.

Then use a 1/2″ drive extension and a 1/2″ wrench

Then use the extractor punch (thin steel stick) to hammer the lock out of that socket (otherwise it’s pretty hard to remove one after you are done).

That’s it … good luck with your adventure and be safe!

Note:  I bought the kit from http://www.bosstoolsupply.com/ online store in Canada … it’s priced at $39.95 CAD + tax + $10 (or so) S/H – so total I payed around $60 CAD. But was worth it to buy as once I removed all four nuts (from 4 wheels) I sold the tool-kit for more or less the same price on kijiji.ca
