Have you ever pressed the button on your Nissan key fob and been met with silence? It’s a common inconvenience, and often indicates a dead battery. If you’re wondering “what battery does my Nissan key fob take?”, you’ve come to the right place. As your trusted Nissan service experts at keyfobx.com, we’re here to provide a straightforward guide to help you identify the correct battery and get your key fob working again in no time.
Even with a dead key fob battery, you can still access and operate your Nissan vehicle. This guide will not only explain the battery type but also walk you through accessing your car and starting the engine when your key fob is unresponsive. We’ll also cover replacing the battery yourself and when it might be time to seek professional help.
Accessing and Starting Your Nissan with a Dead Key Fob Battery
Before we delve into the battery specifics, let’s address the immediate concern: how to use your Nissan when the key fob battery is dead. Nissan Intelligent Key fobs are designed with a mechanical backup plan. Inside each fob is an emergency key that will allow you to manually unlock your car door and start the engine. Here’s how to utilize it:
- Locate the Emergency Key: On the back of your Nissan key fob, find a small release latch or button. Press and hold this to detach and slide out the emergency key.
- Manually Unlock Your Door: Insert the emergency key into the driver’s side door lock and turn to unlock your Nissan manually.
- Starting Your Vehicle: Once inside, you’ll need to start your car. The method varies slightly depending on whether your Nissan has a designated key fob port.
- With a Key Fob Port: Look for a port, often located on the steering column or dashboard. Insert the key fob into this port. Then, press the brake pedal (or clutch for manual transmissions) and press the START/STOP button.
- Without a Key Fob Port: If there’s no designated port, step on the brake pedal (or clutch) and press the Nissan key fob directly against the START/STOP button.
These steps should get you moving even with a non-functioning key fob battery. If you encounter any difficulties accessing or starting your Nissan, it’s always best to contact a certified Nissan service center for assistance.
Identifying the Correct Nissan Key Fob Battery Type
Now, back to the main question: “what battery does a Nissan key fob take?” The specific battery type can differ based on your Nissan model and the year it was manufactured. While your owner’s manual is the definitive source, there are a couple of common battery types used in Nissan key fobs:
- CR2025 Battery: This is a 3V lithium coin cell battery that is commonly used in many electronic devices, including some Nissan key fobs.
- CR2032 Battery: Another 3V lithium coin cell battery, the CR2032 is slightly thicker than the CR2025 but often interchangeable and may offer a longer lifespan.
To definitively determine the correct battery for your Nissan key fob, the most reliable method is to open the fob and check the markings on the existing dead battery. Follow the battery replacement steps outlined below to safely access the battery compartment and identify the exact type you need. You can purchase replacement batteries at most drug stores, hardware stores, and online retailers. Alternatively, your local Nissan parts center will stock the correct battery.
Step-by-Step Guide to Nissan Key Fob Battery Replacement
Replacing the battery in your Nissan key fob is a simple DIY task you can usually complete in minutes. Here’s a 7-step guide:
- Remove the Emergency Key: Flip your key fob over and locate the release button or latch. Press it to detach and remove the emergency key.
- Open the Key Fob Casing: Carefully inspect the key fob casing for a small notch or seam, usually located along the side. Insert a small flathead screwdriver or a similar thin, flat tool into this notch. Gently pry the two halves of the key fob apart.
- Remove the Old Battery: Once open, you’ll see the battery. Take note of the battery’s orientation (+ side up or down) before removing it. You may be able to gently pry it out with your fingertip or the flathead screwdriver if needed.
- Insert the New Battery: Place the new battery into the compartment, ensuring it’s oriented in the same direction as the old one. The positive (+) side should usually face upwards.
- Reassemble the Key Fob: Carefully align the two halves of the key fob casing and press them firmly together until they snap or click securely back into place.
- Replace the Emergency Key: Slide the emergency key back into its slot until it clicks and is securely held.
- Test Your Key Fob: Press the buttons on your key fob to ensure it is now working correctly, locking and unlocking your Nissan remotely.
