A while ago I purchased a set of McGard locking nuts for my car, to keep the new alloys safe and sound. Heard good things about them so thought I'd bite the bullet and get a set..
Anyway, today I thought I'd clean up the alloys up inside etc and paint the calipers while I was at it. So off came the front offside, cleaned up aloy, painted caliper, alloy back on.. Come to do up the locking nut, hear a slight crack.. everything seems fine..
Do the offside rear, same again hear a crack doing the locking nut back up. Then come to take off the nearside rear, slip on the locking nut key and try to undo it and HUGE crack and the locking key slips. Take a look at the key and what do you know it's sheared the top of the nut clean off and left it inside the key, which inturn has cracked all around the pattern. (see pic)

So now I'm left with one sheared nut on the rear with no idea of how to get the thing off as it's hardened steel around the nut, a key which is as good as useless and two calipers still to paint.. On top of my light problems I had the other day.. Can things get any worse [:^(]
I'm contacting McGard about it, but in their leaflet with the key it says replacement keys are £12 but surely this is a design fault somewhere or something? But that still won't take off the sheared one..
Anyone got any ideas of how to get the sheared nut off? Cheaply, as I am skint
