No key detected, according to Altima, despite the fob
Even if the fob locks and unlocks without a hitch, even from a distance, the 2019 Altima claims that no key has been detected. I hear a noise and then some clicking when I press and hold the start button. When I initially stepped inside to turn it on, a malfunction notice appeared.
Mechanic’s Helper: When did you initially discover the mistake? Does the vehicle still start with the key?
We appreciate you taking the time to let us assist you with this issue, and we hope to resolve it shortly.
Please keep in mind that since I don’t know your knowledge or skills, I might need to ask you some questions to get some fundamental information that will help me solve your particular problem.
Sometimes I might have to look for information regarding your issue before I can react, so please be patient. I’m grateful for your patience and will get back to you as soon as I can.
Prior to anything else, check the battery in your car. There ought to be 12.5 volts. You should attempt a jump start if you don’t have a voltmeter. Numerous issues will arise with a depleted battery. Next, check to see if your key fob has a functioning battery. You may lock and unlock the doors with the key fob remote. It should start after 30 seconds of turning the ignition on. If it doesn’t, use the actual key to lock and unlock the driver door and turn on the ignition for 30 seconds. If it still won’t start, there is a problem with the anti-theft system, and a scan tool will be needed to identify the issue.
You must use a scan tool to read the error codes (if any are stored) and to view the data in the antitheft module to see what inputs and outputs the module is recognizing in order to figure out what the issue is. This will reveal whether the key, receiver, module, or any other component of the system is the issue. I am unable to suggest a specific repair for this defect because there are no typical issues with it. If the module has any saved trouble codes, please let me know what they are so I can identify the root cause of this issue.

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.

What is a Nissan key system error?
The Nissan Intelligent KeyTM system warnings in newer Nissan vehicles will show up as one of the following messages in the information display:
When an Intelligent Key is present but the system does not recognize it, a “Key ID Incorrect” alert is displayed.
If your key fob’s battery has to be changed, a “Key Battery Low” alert can show up.
When the key is left outside the car or the key fob battery is already dead, a “No Key Detected” alert could show up.
When the message “Key System Error: See Owner’s Manual” appears, there is a problem with the Intelligent Key system as a whole. If the warning light comes on while the engine is running, you can keep driving the car, but it is advised that you have your system checked at the nearby authorized Nissan dealer. If this warning shows when the engine is off, take note that you might not be able to start it.

Nearly all Nissan key fobs contain a mechanical car key concealed inside in case your batteries run out thanks to Nissan’s Remote Start Key. A small catch exists.

Your keyfob is not required to start your automobile because the ignition button is built to function even if the keyfob breaks. Many automakers have even included a manual start option to the ignition button. Numerous cars, including Mazda and Ford models, have a key slot below the steering wheel. The fob can be inserted to start the engine.
If you don’t have a manual ignition key, push the button while pressing the fob against it. This backup strategy is used by several automakers to guarantee that your car will still operate if your keyfob malfunctions.

Since remote controls are sometimes offered in pairs, it is advisable to change the batteries in every remote at once.

The contacts may become separated from the buttons as they deteriorate. Pressing the buttons repeatedly is one of the greatest techniques to identify worn-out car buttons on car remotes.
Determine which of the following circumstances applies:
- Only certain button presses, or all button presses, function.
- One button operates while the other does not.
