Chimera only supports one color key.

If the keys are for the same attribute, you can build a combined key  
"by hand" by adding additional color wells to the Color Key dialog and  
typing in the appropriate values and selecting the corresponding  
colors (click on a color well to bring up an editor for that well, or  
drag and drop colors from the Render by Attr dialog).

If the keys are for different attributes then the only suggestion I  
have is to make two half-width or half-height images to be displayed  
together, each with one key.  This assumes that there is some  
separation between your two models.  Or use Photoshop to place a key  
(possibly cut from another Chimera image).
