please help anybody,IR remote controles Answered

I have a sony MEX-5di car stereo i bought the remote for it online but they sent me the wrong one
i cant send it back.and the one they sent me isn't compatable.So i cant access all the functions.Is there a way to program a universal remote to work with it.Or can you make a remote work with it by soldering or unsoldering something inside the remote.can i mod the remote somehow so it will run all IR equipped devices.or is it just wishful thinking that this will work so i dont have to spend another 60 dollars on another remote?
