"Key to the Highway" is a blues standard that has been performed and recorded by several blues and other artists. Blues pianist Charlie Segar first recorded the song in 1940. Jazz Gillum and Big Bill Broonzy followed with recordings in 1940 and 1941, using an arrangement that has become the standard.
