I think you are referring to the "intelligent key" feature. As far as I know, it's only available on US model Versas.Sorry typo...should read "switch". I was watching a video on youtube about a button on the door. If I have the key fob in the pocket, I can press a button on the door to unlock it. My car does not have it. Just checking if this is something not a part of in the SL model or something I need to pay extra for. Thanks!
