Is it possible to use the intelligent key remote as a replacement fob for the 2005 G35 coupes that don't come with the system installed?

I'm not sure if anyone has tried to program it to work, or if its even possible?

 

i dont think it is programmable on the same level as the early remotes. Im sure you know that the keyless part of it will definetly wont work and i dont think has been succcessful to be added either.

 

I've been wondering this. Or at least gutting the intelligent key for it's shell?
