Experiencing issues with your Nissan key fob? If your key fob isn’t responding, the most likely culprit is a dead battery. Don’t worry, gaining access to your Nissan and getting back on the road is simpler than you might think. This guide, brought to you by the auto experts at keyfobprog.com, will walk you through everything you need to know about what battery goes in your Nissan key fob, how to access your vehicle with a dead fob, and how to replace the battery yourself.
Even with a dead key fob battery, your Nissan is still accessible and drivable. This buys you the time needed to identify and replace the battery, ensuring you’re never stranded.
Accessing Your Nissan with a Dead Key Fob Battery
The first concern when facing a non-responsive key fob is vehicle access. Nissan Intelligent Key fobs are designed with a mechanical backup plan. An emergency key is housed within the fob itself, allowing you to manually unlock your car door. Here’s how to find it and get inside:
- Locate the release latch on the back of your Nissan key fob. Press and hold this latch to release the emergency key, which you can then slide out from the bottom of the fob.
- Use the emergency key to manually unlock your Nissan door, just as you would with a traditional key.
- Once inside, starting your Nissan requires a slightly different approach, as the key fob is usually needed for push-button start systems.
- Look for a designated key fob port inside your vehicle. This port is often located on the steering column or dashboard. If your Nissan has a key fob port, insert the fob into the port, then press the brake pedal (or clutch for manual transmissions) and push the START/STOP button.
- If your Nissan doesn’t have a key fob port, don’t worry. Simply step on the brake pedal (or clutch) and press the Nissan key fob directly against the START/STOP ignition button. The vehicle’s system is designed to detect the fob even with a dead battery when it’s in close proximity to the start button.
If you encounter any difficulties accessing or starting your Nissan following these steps, it’s always best to consult with automotive professionals. Contact a trusted service center for guidance.
Identifying the Correct Battery for Your Nissan Key Fob
Knowing what battery goes in your Nissan key fob is crucial for a successful replacement. The battery type can differ depending on your Nissan model and year of manufacture. There are a couple of reliable ways to determine the right battery for your key fob:
- Consult your Nissan Owner’s Manual: Your vehicle’s owner’s manual is a valuable resource and should specify the exact battery type required for your key fob. Check the index or the section on keys and remote entry.
- Open Your Key Fob and Inspect the Old Battery: The most direct method is to open your Nissan key fob and take a look at the existing battery. Carefully follow the battery replacement steps detailed below to access the battery compartment. Once you’ve removed the old battery, you’ll find its type clearly marked on the battery itself.
Common battery types for Nissan Intelligent Key fobs are typically CR2025 or CR2032 3V lithium batteries. Both are coin-cell batteries and readily available at most drugstores, hardware stores, and online retailers. While both are 3V and have the same diameter, the CR2032 is slightly thicker than the CR2025 and has a slightly higher capacity, potentially offering longer life. However, your key fob is designed for a specific thickness, so always refer to your manual or the old battery to ensure you purchase the correct type.
You can purchase a replacement battery at numerous locations, or for added convenience, you can order from an auto parts center online to ensure you get the correct type quickly.
Step-by-Step Guide to Change Your Nissan Key Fob Battery
Replacing the battery in your Nissan key fob is a straightforward process you can accomplish at home in just a few minutes. Here’s a simple 7-step guide:
- Remove the Emergency Key: Flip your Nissan key fob over and locate the release button or latch. Press it to detach and remove the emergency mechanical key from the fob.
- Open the Key Fob Casing: Carefully inspect the key fob casing for a small notch or seam that separates the two halves. Use a small flathead screwdriver or a similar thin, flat tool. Gently insert the tool into the notch and carefully pry open the key fob. Avoid using excessive force to prevent damage to the casing.
- Remove the Old Battery: Once the key fob is open, you’ll see the battery. Take note of the battery’s orientation (positive side up or down) before removing it. You may be able to gently pry it out with your fingertip or use the small screwdriver if needed.
- Insert the New Battery: Place the new battery into the battery compartment, ensuring it’s in the correct orientation as you noted in the previous step. It should snap into place securely.
- Reassemble the Key Fob: Carefully align the two halves of the key fob casing. Press them firmly together until they click back into place, ensuring a secure closure.
- Replace the Emergency Key: Slide the emergency key back into its slot in the key fob until it clicks or locks securely.
- Test Your Key Fob: Test the buttons on your key fob to ensure it’s working correctly. Lock and unlock your Nissan remotely to confirm the new battery is functioning.
When to Seek Professional Nissan Key Fob Service
While battery replacement is simple, some key fob issues require professional attention.
- Reprogramming: If you replace the key fob itself or are having issues even after battery replacement, reprogramming might be necessary. Nissan recommends visiting a dealership for key fob reprogramming, as it’s a complex process involving security systems.
- Persistent Issues: If you’ve replaced the battery and your key fob still isn’t working, there could be other underlying problems with the fob itself or your vehicle’s receiver. In such cases, professional diagnostics are recommended.
You can easily schedule service at a Nissan dealership if you prefer professional battery replacement or suspect more complex issues.
