Locking Wheel Nut /Bolt

Can anyone help - I've lost the adaptor 'key' to my locking wheel bolts, is there anywhere that identifies / sells replacements?

Probably not I guess ?

I haven't used one myself, but you can buy removal kits for locking nuts, as used by the AA, like this : http://www.dynomec.co.uk/indexEnglish.html

When I had a similar problem on a Mk3 Golf I got three locking nuts off myself by hammering on a socket to use with a breaker bar, although I had to get the local garage to get the last one off which wouldn't give in (the garage had better tools for the job anyway!) The type of locking nuts you have might not suit this method though?
