Keyless Remote compatibility 94 S320
 

I was wondering if anyone knew if I could use a newer mercedes remote with my S320. I have a 1994 S320, and need to replace the remote. I went into eBay, and their is a guy selling a Mercedes remote that comes off a 2003. I like the way the remote looks and was wondering how compatible the remotes are? I know Im going to have to cut a new key...

Oh, and since my remote only has one button, and the newer ones have 3 or 4 buttons, can they be programmed to pop the trunk? I also have an extra remote from my wifes ML320...it has four buttons (lock, unlock, tailgate, and panic), can I get this one programmed to work with my 94 S320?

Thanks for your help.
