master key

Can Anyone Help, I Bought A 2007 Toyota Highlander From A Dealer And The Only Key They Gave Me Was The Valet. They Said They Didnt Have The Key Cutting Code. I Go To Toyota N Buy A Master Key And Get Told That Because The Vehicle Came From The States That They Are Not Sure If I Have To Try N Contact The Dealer Down There For The Code Or If I Can Go To A Key Cutting Place And Have Them Put The Request In. Isnt There An Easier Way To Get The Code So I Can Take It To Get Cut N Then Back To Toyota To Get Programed? U Can Find Everything Else Online.
