Anyone know where the locking nuts for the above are stored?

Without trying to sound 'sarky' they are usually on each wheel to stop them getting nicked? Did you mean the key that gets them open?

sure did...........:hihi:

The key is usualy kept in the boot with the small wheel brace and a small lever that pulls wheel trims off if you have them (its all in a little bag) If not then its the dealers.

If you can't find it (mine got pinched along with the radio - it was in the glove box) your local garage will have the tools to get the locking nuts off.
