How can I put the code in?

I recently bought a cd player for my renault modus of my friend who didnt have the instruction manual. I plugged the cd player in but it isnt coming up with code or asking for the code??? Help what could this be?

its possible that the radio is linked to the engine management modules, meaning it can not be fitted into another car without being reset by a professional
