Update on keys - this model has the smartkey system. The fobs and chips have to have their codes added to the BCM to work. Was hoping the Infinity dealer owned by the VW dealer that sold me the Versa would do the Consult III programming for me, but they were afraid to. They did cut all of the blades for me (no charge) and called the Oak Ridge Nissan dealer to do the programming. $109 including tax to program the five (total)blades and two fobs. I purchased blades and fobs on eBay. All working great, now.
