The Nissan Murano is known for its luxurious features and practicality, but what happens when the key fob stops working? A non-functioning key fob can be frustrating and can significantly impact your ability to access and start your vehicle. This article provides a comprehensive guide to diagnosing and fixing common issues that cause the Nissan Murano key fob to stop working.
Understanding the Purpose of the Nissan Murano Key Fob
Before diving into troubleshooting, it’s essential to understand what role the key fob plays in your Nissan Murano. The key fob serves as a remote control for various functionalities of the vehicle, including:
- Remote Lock/Unlock: Enables you to lock and unlock your doors from a distance.
- Engine Start/Stop: Allows keyless ignition for a seamless start experience.
- Panic Alarm: A safety feature that permits you to trigger the alarm in an emergency.
Given these critical functions, it’s clear that a malfunctioning key fob can lead to significant inconveniences.
Common Reasons for Key Fob Malfunction
Several factors can cause a Nissan Murano key fob to cease functioning. Understanding these reasons is the first step towards effective troubleshooting.
Dead Battery
One of the most common reasons for a non-functioning key fob is a dead battery. Key fobs typically use a small battery, which, like all batteries, will eventually lose its charge over time.
Interference from Other Devices
Sometimes, electronic interference can play a role. Devices such as mobile phones, other car keys, or electronic devices can disrupt the signals sent to and from the key fob.
Mechanical Damage
Dropping the key fob or exposing it to moisture can lead to mechanical failure. Physical damage can disrupt the internal mechanisms or the circuits that allow the key fob to operate correctly.
Programming Issues
Key fobs can sometimes lose their programming due to various reasons, including battery change or electronic glitches within the vehicle. A loss of programming will render the fob useless until it is reprogrammed.
Basic Troubleshooting Steps
If your Nissan Murano key fob stops working, follow these basic troubleshooting steps to identify the problem.
Check the Battery
The first step to take when your key fob isn’t working is to check the battery. You can easily change the battery in most key fobs.
Steps to Replace the Key Fob Battery
- Locate the Seam: Look for the seam on the edge of the fob.
- Open the Fob: Use a flathead screwdriver to gently pry open the fob.
- Replace the Battery: Remove the old battery and replace it with a new one, ensuring that the positive side faces the correct direction.
- Reassemble the Fob: Snap the fob back together, ensuring it clicks into place.
If the key fob still doesn’t work after replacing the battery, it may be time to explore other options.
Inspect for Damage
Take a moment to examine the key fob for visible damage. Look for any signs of cracking, moisture, or other issues that might indicate the fob is broken. If you notice any damages, you may need to consider purchasing a new key fob.
Test for Signal Interference
If you are facing issues even after replacing the battery, try testing the key fob in a different environment:
- Move away from electronic devices or any appliances.
- Use your key fob at a distance from the vehicle to determine if the issue is related to signal interference.
Advanced Troubleshooting Techniques
If basic troubleshooting does not yield results, consider moving on to more advanced methods to get your Nissan Murano key fob working again.
Reprogramming the Key Fob
In cases where the key fob has lost its programming, reprogramming may be necessary. Here’s a general outline for reprogramming the key fob for most Nissan Murano models.
Steps to Reprogram the Key Fob
- Enter the Vehicle: Sit in the driver’s seat and close all doors.
- Insert the Key: Insert your key into the ignition.
- Turn the Key: Turn the key to the “On” position and then back to “Off” quickly.
- Repeat: Do this 6 times within 10 seconds. On the sixth turn, leave it in the “On” position.
- Program the Key Fob: Press the “Lock” button on the key fob. After this, wait for a chime to indicate that you are in programming mode.
- Complete the Process: Follow the instructions provided in your vehicle manual to complete the programming, including programming any additional fobs.
Keep in mind that specific instructions may vary by model year, so always refer to the owner’s manual for precise guidance.
Consulting a Professional
If you have tried all the previous steps and the key fob still doesn’t function, consider contacting a professional. Visiting a Nissan dealership or a reputable locksmith can provide you with additional solutions. They have the necessary tools and expertise to diagnose and repair the issue accurately.
Preventative Measures to Avoid Future Issues
Once you have resolved the key fob issue, consider implementing the following preventative measures to avoid future problems.
Regular Battery Checks
Make it a habit to check your key fob’s battery regularly, especially if you notice reduced response time. Replacing the battery every couple of years can ensure smooth operation.
Avoid Exposure to Wet Conditions
Since moisture can damage the electronic components of the key fob, it’s best to keep it dry. If you’re caught in the rain, try to keep the key fob protected in your pocket or bag.
Limit Key Fob Exposure
Keeping your key fob away from electronic devices can reduce the chances of interference. Assigning a specific place for your fob can also help.

What should I do if my Nissan Murano key fob is not responding?
If your Nissan Murano key fob is not responding, the first step is to check the battery. Many key fob issues stem from a dead or dying battery. You can replace the battery by opening the key fob with a small tool or a flathead screwdriver, usually by inserting it in the seam of the fob. Once opened, replace the old battery with a new one of the same type, ensuring the positive side is facing the right way.
If replacing the battery does not solve the issue, it may be time to reprogram the key fob. This can often be done at home for some models, but might require visiting a dealership for others. Refer to your vehicle’s user manual for specific reprogramming instructions or consult a professional to ensure your key fob is properly synchronized with your vehicle.
How can I tell if the key fob battery is dead?
One of the easiest ways to determine if your key fob battery is dead is to observe its responsiveness. If the key fob is not working from the usual distance or requires you to be extremely close to the vehicle for it to function, it’s a strong indicator that the battery might be low. Additionally, if the button presses are unresponsive or inconsistent, this can also signal a battery issue.
Another method to check the battery is by using a spare key fob if you have one. If the spare fob works without any issues, it confirms that the primary fob likely has a dead battery. Consider testing the fob with a multimeter if you have one available, as this will give a clearer picture of the battery’s current state.
Can I replace the key fob myself?
Yes, you can replace the key fob yourself. Many Nissan Murano owners successfully change their key fob batteries or even replace the entire key fob without needing professional assistance. If you have the right tools, which usually include a small screwdriver and a replacement battery, the process can be quite straightforward. Refer to your vehicle’s manual for instructions on how to open the fob and replace the battery.
However, if the entire key fob is malfunctioning or you need a complete order of a new key fob, it may be more complicated. In this case, it is advisable to consult a dealership or a certified locksmith who specializes in automotive keys. They can ensure that the new fob is programmed correctly to work with your vehicle.
Why is my key fob working intermittently?
Intermittent functioning of a key fob can be caused by several factors, with a dying battery being one of the most common culprits. When a battery is low, it may not provide enough power to communicate effectively with your vehicle, leading to sporadic responsiveness. In this case, replacing the battery is a simple first step that might resolve the issue.
Another reason for intermittent key fob functionality could be interference from other electronic devices. In some situations, strong radio frequencies or nearby electronics might disrupt the key fob’s signal. If you suspect this may be the case, try using the fob in different locations or remove any nearby devices to see if the situation improves.
What tools do I need to troubleshoot my key fob?
To troubleshoot your Nissan Murano key fob, you will mainly need a small flathead screwdriver to open the fob case and access the battery. Additionally, having a replacement battery on hand is essential for quick replacements. Depending on the type of key fob, you may also want a pair of scissors or tweezers, especially if the battery is small and hard to handle.
If you are planning to reprogram the key fob yourself, having access to the vehicle’s user manual will be crucial. It can provide specific codes or procedures unique to your model. Some owners also find it helpful to have a multimeter for checking the battery’s charge level or signal strength.
Should I consult a dealership or a locksmith for a non-working key fob?
Consulting a dealership or a locksmith is a good idea if you have tried all troubleshooting steps and your key fob is still not functioning. Dealerships have the specialized tools and knowledge to diagnose and fix key fob issues correctly. They can also provide you with a replacement fob if necessary, ensuring it’s properly programmed to work with your vehicle.
On the other hand, locksmiths often offer a more cost-effective solution for key fob issues, especially for battery replacements and simple reprogramming. It is essential to choose a locksmith with experience in automotive keys to ensure the process runs smoothly. Either option can save you time and frustration if you are dealing with a malfunctioning key fob.
