Hot wheels beast bash playset...no car non Talking

The voice presently does not work!  I am working on this but don't know if I can fix it. The mechanics, I  mean the buttons and levers that move parts all seem to work but you have to push the buttons, levers etc. There is a not on original box which I don't have that says it doesn't work with all hot wheels so be careful there. No cars included. Some minor play wear to the toy
