2014 Sentra Key program issues
 

I have a 2014 Sentra with the key fob built into the head of the key. The fob has 4 buttons. I lost one of my keys. So I ordered two replacement keys on Amazon. I tried programing the new keys and was able to get the new keys to lock and unlock using the remote but when I put the key in the ignition it will not start the car. On the dash it shows a Red Car with a key in it. So I'm guessing the car is not recognizing the new key. The old key will still start the car but will not lock and unlock the car using the old key fob. Any Suggestions
