Diagnosing the Issue: 2009 Nissan Altima Won’t Start – No Key Detected

YouTube video

Have you ever encountered a situation where your 2009 Nissan Altima won’t start, and a “No Key Detected” message appears? This can be frustrating and confusing, especially if you don’t know what the underlying problem is. In this article, we will delve into the details of diagnosing and fixing this issue, so you can get your car back on the road.

Understanding the Problem

The video transcript starts with the narrator mentioning that a 2009 Nissan Maxima was towed in for a no-start issue, displaying a “No Key Detected” message. The narrator is uncertain about the exact problem but hopes that the video will shed light on the issue.

Checking for Battery and Reprogramming Options

To begin troubleshooting, the narrator demonstrates two common methods suggested by others. The first is holding the key against a specific location to reprogram it if the issue is caused by a low battery. However, this method proves ineffective.

The narrator then reveals another tip, which involves inserting the key into a certain slot to re-detect it. Unfortunately, this method also fails to resolve the problem. Thus, it becomes evident that the issue lies beyond a mere battery or reprogramming problem.

Exploring the Steering Control Box

After examining other videos for potential solutions, the narrator discovers the concept of a steering control box that could be causing the issue. The narrator demonstrates the location of the box by removing a panel and points out the box responsible for the problem.

Attempting a Fix: Hitting the Box

In an attempt to rectify the issue, the narrator decides to tap the box with a hammer and a punch from behind without removing the cover. Surprisingly, this method proves successful, and the car starts functioning again. This indicates a faulty interlock steering interlock, a common problem with these vehicles.

Replacing the Faulty Interlock Module

Although hitting the box temporarily resolves the issue, it is essential to address the underlying problem by replacing the faulty interlock module. The narrator explains that a new interlock module is on its way, and provides information on how to replace it.

To replace the module, the narrator demonstrates accessing the module by removing various screws and connectors. Finally, the old module is removed and replaced with a new one, which allows the car to start without any issues.

Unexpected Complications with a Dongle

After successfully replacing the module, the narrator encounters a new problem. While trying to reprogram the key using a dongle, the car fails to start, and the lock and unlock function becomes non-operational. A specialist is called in to investigate, but he suggests that there may be a PCM issue and recommends taking the vehicle to the dealer.

Returning to Factory Settings

Concerned about the unresolved issue, the narrator decides to remove the aftermarket module and reinstall the factory one. It turns out to be a wise decision as the “No Key Detected” problem is rectified and the car starts functioning normally again.

Conclusion and Lessons Learned

In conclusion, diagnosing and fixing a “No Key Detected” issue in a 2009 Nissan Altima can be a complex process. While some problems, such as a faulty interlock module, can be resolved with simple steps, other complications, like the use of a dongle, can create further issues.

The key takeaway from this experience is to exercise caution when attempting to resolve the problem yourself. It is crucial to thoroughly research and read reviews before using aftermarket products or tools that may cause unforeseen complications.

If you encounter a “No Key Detected” issue in your 2009 Nissan Altima, it is advisable to consult a professional and consider taking your vehicle to the dealer for a comprehensive diagnosis and resolution.
