Introduction

In this article, we will discuss the process of replacing the remote key fob battery in a Nissan Murano. The Nissan Murano is equipped with an intelligent key that not only functions as a standard key fob but also features keyless start capabilities. We will walk you through the step-by-step process of replacing the battery and provide tips and recommendations along the way to ensure a successful battery replacement.

Key Fob Features

The key fob for the Nissan Murano allows you to perform various functions from a distance. This includes locking and unlocking the car, opening the trunk or rear hatch, and even starting the car without physically inserting the key. The key fob works by sensing the key’s proximity to the car, eliminating the need to manually press buttons. However, all these functions require a power source, which is why it is crucial to address the low key battery warning when it appears.

Addressing the Key Battery Low Warning

When the key battery is low, the car’s system will display a warning message to alert you. It is essential to address this warning to ensure the continued functionality of the key fob. Fortunately, replacing the key fob battery is a simple and straightforward process. Here’s a step-by-step guide to help you through it:

  1. Acquire the correct battery: Consult your owner’s manual to determine the appropriate battery for your Nissan Murano. In the case of a 2018 Murano, it requires a CR2032 battery. Ensure you have the correct battery before proceeding.

  2. Open the key fob: On the back of the key fob, locate the emergency blade section and push the switch forward to release the blade. Remove the blade from the key fob.

  3. Pry open the key fob: Using a pocket knife or a pry tool, gently pry open the key fob by inserting your tool into the slots on the back of the key fob. Start prying from the mid-line and work your way around until the key fob opens.

  4. Locate the battery: Once the key fob is open, you will see the battery compartment. It is located on the bottom side of the key fob.

  5. Remove the old battery: Using your fingers or a tool, carefully remove the old battery from its compartment. Be cautious not to damage the key fob or the battery.

  6. Install the new battery: Take the new CR2032 battery and slide it into the battery compartment. Ensure that the positive and negative terminals align correctly.

  7. Close the key fob: After installing the new battery, close the key fob by aligning the two halves and pressing them together until they snap back into place.

  8. Test the new battery: Start the car and verify that the key fob battery warning has disappeared. Additionally, test the key fob’s functions to ensure it is working properly.

Frequency of Battery Replacement

The frequency of key fob battery replacement varies based on usage. It is recommended to have spare batteries on hand and replace the battery as soon as the warning appears. The more frequently you use the key functions, such as remote start or locking/unlocking, the faster the battery will drain. It is a good practice to set reminders every two years or based on your usage patterns to ensure timely replacements.

Conclusion

Maintaining your key fob’s battery is essential to ensure uninterrupted functionality. Replacing the battery in a Nissan Murano key fob is a simple process that can be done at home or on the go. By following the steps outlined in this guide, you can address the “Key Battery Low” warning and continue enjoying the convenience and features of your intelligent key fob. Remember to use the correct battery model, such as the CR2032, and always exercise caution when handling the key fob to avoid any damage.
