How to make a copy of a 2000 Ford Windstar key?

I found blanks online with chips. Would these work if I get them cut exactly like the key I have right now and where would I take them to do this?

An automotive locksmith can cut and program new keys; without the programming the keys won't start the engine.

I agree with FlagMichael's opinion and I think for that you need to make a contact with your local locksmith as I do for any security need to "Las Vegas nv Locksmiths".
