local txd, dff, state 
  
bindKey( 'F6', 'down', 
    function( ) 
        state = not state 
        if state then 
            txd = engineLoadTXD( 'models/fbi.txd', 490 ) 
            engineImportTXD( txd, 490 ) 
            dff = engineLoadDFF( 'models/fbi.dff', 490 ) 
            engineReplaceModel( dff, 490 ) 
        else 
            destroyElement( txd ) 
            destroyElement( dff ) 
        end 
    end 
)

I don't know, but I think my code should also work, I could have used a variable like you did, but I wanted to see if it was possible to make it without it.
