I'm not sure I understand your question. Are you using different calls to 
levelplot() for the different z variables ? What's wrong with the default 
colorkey for each such plot ? 

In any case, the arguments controlling colorkey are described in the help page 
for levelplot. Another way to control the scales (to be same across different 
calls to levelplot, say) is via the 'at' argument to levelplot (this can be 
used in a manner similar to what might have been expected from a 'zlim' 
argument, had one been available).

Hope that helps,
