Help me find a key for this nutlug!!

Hi there!

So I bought my 2004 Dodge Caravan a few weeks ago and went for a roundtrip to the US westcoast. I got a flat tire on my way and found out I have 1 special lock lugnut (see photo) on each wheel and don't have the key for them. Does anybody have the same lock lugnuts or idea where I can get the key for these?? Any help appreciated!

Thanks, Adam54064

Just use a rounded nut remover... this particular style is the best. You'll never be able to find an exact key, so many look alike. See my link:
