I need a new key for my car made?

I just got a used 2003 Honda ex and the owners who sold it to me only gave me the secondary or spare key. When we asked them about the original key they said that they lost it. The key that I have doesn't fit into any of the locks. So where do I go to get the original key made?

Dealer

You could try a locksmith, but odds are it may be a little cheaper; but not a guaranteed fix here unless it is just a plain metal key and has no remote lock features; and even then he may have a problem without a key to work with.

I go with the dealer on this one

I too would go to a honda dealer, they can create the correct key.

They don't have a key that fits ANYTHING? Do you have a signed title? What does the "spare" key do, start the car but not open the back? Pretty sure the dealer will require the car and title before they make you a key.
