Meaning of "Somebody Changed The Lock" by Dr. John

The lyrics of "Somebody Changed The Lock" exemplify feelings of betrayal, rejection, and loss of control. The act of changing the lock on the door symbolizes a barrier being put up between the narrator and someone they once trusted or had a close relationship with. The inability to use their key represents a loss of access and connection to that person or that part of their life. Standing on the porch all night long indicates feelings of uncertainty and being left out in the cold, both physically and emotionally. The repetition of the key not fitting the lock emphasizes the sense of being shut out and unable to regain what was once familiar and comforting. Overall, the lyrics capture the emotions of abandonment and helplessness when faced with sudden changes in a relationship or situation.
