For Sale: One 2013 Kia Soul Key Fob, with spare key. The ignition key fits into the fob when not being used. The car was totaled in a crash and we were given the fob to hang on to. I am not sure how they work - if they fit any Kia Soul, no matter what year, etc. You can do some research on that and take a chance. It is priced reasonably, as they are very expensive to replace. Pick up in Woodland Hills.
PS - I also have a complete Owners Manual from the same car, if you are interested.
