help with alloy wheel locking bolt

[saskak]

What about buying a cheap set of PSA locking bolts with the key on eBay mate: (may have to check they are the same or grind one pin off)

I thought about that and managed to count all available keys on ebay, they were 37 different combinations up for sale at the time when I looked. Most will probably be off by a fraction of a mm. By the look at the photos, some seemed like good candidates. Each one was ~£25.
I phoned a mobile tyre company that said will do it for £90 for all 4. I think it will be cheaper than either trying with approximate key or buying the expensive Dynomec set. I will see if they can do it.
