I lost my lug nut key and i'm wondering if there is a universal key i can buy somewhere or my best bet for taking off my tires

 

what kind of pattern is it??
sometimes if you go into a tire shop, they have keys for sale

 

find a socket that'll work, or find one you can hammer on somewhat tight

 

If its a honda lock just take it to a dealer. they have all the keys available

 

You should have a card with your manual with a code on it. I've got OEM lock nuts on my car, and there's a card in my glovebox from McGard, the company that makes the lock nuts with a code on it for a replacement.

If not, take it to the dealer and they will be able to get a replacement.

If you're in need to take them off right away, hammer a 12 point socket onto it and should be able to crack it loose.

Is yours the OEM puzzle style lock, or splined tuner nuts?

 

you should be able to order another one from McGuard

 

If you can't find a replacement key matco and snap on sells a special socket to get those out
