Hello, I have a 2016 Nissan Versa Note. About 2 weeks ago the outside keyless entry unlock buttons stopped working. Now both of my key fobs have stopped working. I have to remove the key to open the door, and I have to hold the intelligent key up to the start button until it beeps to start the car. Then once I'm in the car, the key button flashes the whole time. Any ideas on how I can fix this? It's very frustrating considering I purchased the car new last year.
