UKPassats

Thanks for your answers....but my question is:
Should I buy this from Amazon £10, if it's compatible ?(see foto)
Then I can remove the old bolts myself without the cost of going to garage.
I'm a poor bloody pensioner.

this advert on amazon, is it the same as my car wheel nut, I lost the key. Thanks.
see the two pics here.

I have lost the wheel nut key for my 2003 Passat.
How can I get one online? what can I look for?
My dealer wants to charge me 73 pounds, too steep!!
I attach pic of the hole.
