Nissan No Key Detected: Causes and Fixes

Nissan is a special class of a vehicle and the automakers equip its different generations with amazing features. The car’s ignition Intelligent Key uses wireless radio frequencies. The high-performance coil-on-plug (COP) ignition system of Nissan has a unique operating mechanism. The powertrain control module (PCM) not only controls the individual coils. It relies on timing triggers on the input signal generated in the crankshaft position sensor. 

Besides, the PCM also receives these input signals from the two camshaft position sensors and uses them to change spark timing. But like all car makes and models, the Nissan ignition is also susceptible to damage. When your Nissan cannot detect the key, what happens? Join me as I walk you through the reasons and remedies. 

What Causes ‘No Key Detected’ in Nissan?

Typically, if your Nissan ignition systemis unable to detect the Intelligent Key (or Nissan Vehicle Immobilizer System, NVIS) you’ve got a minor issue on your hands. But what could trigger it? You may need to be on the lookout for the following:

Interference with Nissan Vehicle Immobilizer System (NVIS)

The ignition system of most Nissans is integrated with a security feature like the NVIS or Nissan Anti-Theft System, NATS. It requires only the key registered with the car to start the engine. It means, if you insert an unregistered key, the system will be unable to detect it. 

The NIVS or NATS comprises a transponder that’s susceptible to interference. Usually, the radio frequency token, which is the source of the signal, is often close to the key. This kind of interference might deactivate the entire ignition system, causing the engine not to start. 

Improper key authentication

There is a chance that the system is not able to properly authenticate the key. When this happens, the ‘No key Detected’ indicator light on your vehicle’s dashboard will stay illuminated. As a result, when you attempt to start the engine, a message will pop up. The key may not have been properly authenticated.  

RFID close to Nissan Key

If the Radio Frequency Identification (RFID) chip is close to your Nissan key, the ignition may not be able to detect the key. “Why?” you may want to ask. RFID is a non-contact, wireless device that uses radio frequency waves. With antennas, RFID tags, and RFID readers, the RFID system uses waves to automatically identify things and transfer data. One of the poignant symptoms of a close RFID token is a no-start condition. 

Interference with Intelligent Keys 

The modern technology in the ignition system which Nissan models rely on is RFID. As a wireless, no-contact device, the radio frequency stem is unable to receive signals. Once its signal reception is deactivated due to interference, the system won’t be able to identify any entity. Such interference causes the instrument cluster to display such a warning as, “Incorrect Key ID”. In the worst case scenario, the cluster will show “No I-Key detected, meaning that connection to the signals from the Intelligence Key is lost. 

Another symptom such interference might cause is that your engine will not start. Or, you may not be able to receive any response when you press the Stop or Start button. Most Start/Stop operations on the buttons of the fob and door request switches will become erratic and intermittent.

How to Fix Nissan’s ‘No Key Detected’ Problem

Truth is, the kind of remedy to apply depends largely on the result of the diagnosis carried out on the car. As for the remedies, there are different strokes for different folks. Obstruction and loss of data signal are major issues here, and you’ve got to take each one at a time. Let me say that unless you have comprehensive DIY expertise and experience, don’t try to fix any of these issues. Leaving the fix for a professional to handle will be the best bet. Otherwise, any little error may cost you a lot of bucks.

How to fix RFID close to the Key

For Nissans that have their RFID installed close to the key, all you need to do is to uninstall and reinstall it some distance away. This way, the RFID will not interfere with or obstruct signals the key is designed to receive. But again, allowing a professional will be the way to go. They’ll do a good job.

How to Fix NIVS or I-Key Interference issue 

If your Nissan is equipped with I-keys or NATS, the symptoms resulting from interference are intermittent. Hence, it makes diagnostic readings a little bit challenging. Yet, there are scans that professionals will carry out to ascertain where the signal interference is coming from. 

What do you do? A diagnosis is needed. If the scan doesn’t indict the RFID, an aftermarket alarm system on your Nissan can constitute signal interference. Other culprits include a radar detector or any electronic device. Signals coming from the radio frequencies can also interfere.   

How to Fix key authentication issue

The first culprit may be the battery. It is either the battery is low or dead. The remote key functions might also be having problems. Start by changing the battery if the ignition or RFID system is unable to recognize your Nissan key. If this process doesn’t work, it’s time to reach out to a Nissan Autocare Center around you for help. Alternatively, you may call on a certified professional. They’ll run a scan and recommend possible solutions. Either way, you can be sure of an excellent job. 

FAQs

How Do I Diagnose Nissan equipped with I-Key?

What diagnosis should be carried out on your car? First, you need to check the condition of your battery: is it charged or dead? If it doesn’t have sufficient power, it may likely trigger the ‘no key detected’ error message. Again, you need to locate the I-key. Check if the Intelligent key is installed close to RF interference. Typically, the key is where it’s protected from this interference. 

Can I Start a Nissan with a Dead Key Fob?

Yes, if your Nissan key fob battery dies, you can still start the car. Unlocking your Nissan with a dead key fob battery simply requires you to flip the key fob back. Then push the release latch over. It is that straightforward. 

Final Thoughts

As I conclude my auto discussion with you, you must pay attention to all the signs asap. Otherwise, a sudden Nissan ‘No key detected’ fault warning can cost you your job or a life-transforming investment. Make sure you call on professionals and Auto care nearest to you. You’ll need to take your car for regular scheduled servicing and maintenance. This way, you can avoid issues, specifically the ‘no key detected’ message. I hope you ensure safety always.
