Even if the battery in your Nissan fob is still good, there may be times when the car doesn’t recognize it. The battery is usually either dead or low, but your Nissan’s remote key functions could not be working properly. Reach out to our service department and we’ll be pleased to help if changing the battery doesn’t work.
Either the car’s electrical control system or the key fob have an issue. On rare occasions, cell phone interference interferes with the system and produces problems that result in the “no key” warning light. I would first advise performing the complete re-programming procedure on the key fob to see if that fixes the problem. If not, programming a known-good key fob would be the next course of action. If it doesn’t fix things, any accessible software updates should be installed if the electronics controlling the system are flash programmable. The factory service manual contains a decision tree that can be used to “back in” to the problem’s beginning if that doesn’t fix it. In your situation, it is clear that the controller is transmitting a signal to turn on the warning light. However, if the key fob is fault-free and there is no external RFI/EMI interference, it is possible that the controller is malfunctioning. My best bet is that the problem is with the key fob, therefore you should start by reprogramming it or trying a different one. Request an electrical component/circuit diagnosis, and the YourMechanic-delivered qualified mechanic will take care of this for you if you want these steps carried out by a professional mechanic. Please don’t hesitate to get in touch with YourMechanic again if you have any additional queries or worries; we’re always happy to help.

It would seem that the NVIS (immobilizer) system is content with the key IDs because the car starts.
There are three internal reception antennae (the fourth appears to be functional and accepts external remote unlock orders). If the vehicle won’t start without the slot, one or more of the internal antennae must be damaged (they are all wired to the BCM…so if there is no issue with the antennas, the BCM is the next logical stop).
You must have the CVT sedan, I suppose. Can you start the vehicle with the key fob positioned directly above the passthrough aperture into the cabin, below the deck of the rear glass, and close to the reception antenna? If so, it might simply be the front of the car’s antenna that is broken or unplugged (one in the centre console, one in the shifter console). the pictures underneath.
If all three antennas are present, connected, and appear to be in working order (you could try replacing one), and there is still no start without using the key slot, then there must be a problem with the BCM that controls each of these antennas. Of course, getting to the BCM is a major pain because it is up behind the instrument cluster.
