I am new to this forum and I just purchased a 2004 G35 coupe with 20" SEVAS wheels and the wheel lug nut key is missing. The lug nuts are a open type and have a ten points and they look to be evenly matched splines. Alll the lug nut look the same. Any info. would be would be helpful.
Thanks

 

You can always try bringing it to a wheel/tire shop and seeing if they happen to have a key that'll remove them. If so have them take them off (unless they'd sell you the key, unlikely) and replace them.

If they're extended and threaded deeply enough you can try threading in a new bolt and see if that'll break them loose, but I wouldn't do that as a first option.

Post a picture of them and maybe someone can point you in the right direction for finding the manufacturer to contact for replacing the key.

If all else fails try to contact the previous owner or dealership you bought it from and get their help.
