So last night I had a puncture, one junction on the A1m short of home, to the offside rear just before it was about to get dark.

Could it get worse? Yep!

Popped the locking wheelnut key on and started trying to loosen it. Not moving, not moving, crack!

About a 10mm chunk broke from the wall of the key - and I couldn't get it to purchase after that.

Luckily the AA man was able to get around it using his jack to support his breaker bar.

It's an 8 month old car though and the first time I've had to use the key, so very not impressed.

Ford dealer suggested that 'a few have failed'... It's clearly a cheaply made component, but what a terrible item to compromise on.

Just glad it was on the return journey as I'd had my dogs in the car earlier too.

I had to get a Ford dealer to remove the rear lock nuts on my 2007 Focus with what I assume was an air chisel frown
Later ones seem to be a single piece of metal, but the ones that were 2 pieces were a nightmare - in my case the key in the middle broke out leaving a nut that nothing would turn & a locknut remover tool couldn't fit over without damaging the alloy.
Would have expected it to have lasted longer than a few months though - IIRC mine lasted 4-5 years before disintegrating.
If you decide to replace them, watch out - there were some subtle changes in the cone angle used for the Focus at least during the Mk2 - Mk2.5 phase, make sure the replacement is the same shape as the one it replaces.
Seems like they have history with poor locking wheelnut keys then! Mine is a Mk3, new in March and though it's already done 22k the only people who have touched it is the supplying dealer.

I honestly agree we'd be better off without them most of the time - in this day and age what value to a thief would an OEM set of ford alloys represent?

We recently discovered that the 18inch Rays alloys on the wifes car had no locknuts on them and they haven't gone walkies.

what do you mean the aa man was able to use it by supporting his breaker bar with a jack?

if you mean the nut was done up so tight that even with a breaker bar he couldn't budge it by hand and used a jack on it, then i'm not surprised your locking wheel nut key broke, the nut was far tighter than the locking wheel nut key would ever have been designed for
I think he means as a solid support beneath the breaker bar so that there was not the waving about that you would get trying to release the lock with 2 hands whilst leaning on the breaker bar.
This exactly. The key snapped with just me and the 6inch bar in the ford toolkit for persuasion
