Somebody done changed   Somebody done changed the lock on that door   Somebody done changed   They done changed that lock on that door   'Cause the key I got won't fit that lock no more      Now I came home last night about half past ten   Tried to get the key in the lock but I couldn't get it in   'Cause somebody done changed   They done changed that lock on that door   'Cause the key I got won't fit that lock no more      I looked through the window to see what I could see   She was talking to someone else   I know it wasn't me   She said, "Daddy, daddy, daddy, daddy, you don't have to go   'Cause I done changed, I done changed that lock on my door"      She changed the bed around, even painted the door   She even changed the carpet, I mean on the floor   My baby has changed   Oh she done changed that lock on my door   'Cause the key I got won't fit that lock no more      Well, I walked down the street, lookin' where I used to go   She's got a mean black snake now, and I can't go there no more   My baby has changed   She done changed that lock on my door   And the key I got won't fit that lock no more
