Alloy wheel locknut

[kaybee]

Hi

I am a proud owner of a Nissan Pixo 1.0 ( 67bhp ) N-TEC.

I have a question. I bought it from an auction and it has alloy wheels with a locknut. Unfortunately the car doesnt contain the key.

I am worried as my wife will be using it and if it got a puncture i'd be stumped.

what is the best way to go about getting this key. I am assuming dealer is the only solution. there is a seller on ebay that sells these keys too. he asked me if i could get the code but i don't know where to look for this code. Car came with no paperwork whatsoever. Thanks for all the help you can offer.
