Is it possible to install keyless entry? One of the few things that I don't like about our sedan is that it didn't come with it from the dealer. Though I am a firm believer that chivalry isn't dead, I am having an issue with the passenger side door. If I had a dollar for every time that I made it all the way to the passenger door to open it for my wife to get in only to remember that it doesn't have a lock on that side I would have enough cash to get a 2007 G6 GTP. I actually like the look of the door without the lock there but I like being able to open the door for her first before I get in mine. Any suggestions?
