Experiencing issues with your Nissan key fob? If your key fob isn’t responding, the most likely culprit is a dead battery. Knowing what size battery for your Nissan key fob is crucial for a quick and easy fix. Don’t worry, replacing the battery is a straightforward task you can often handle yourself, saving you time and money. This guide from your trusted experts at Keyfobx.com will walk you through everything you need to know about Nissan key fob batteries, ensuring you get the right size and get back on the road without delay.
You might be surprised to learn that even with a dead battery, your Nissan is still accessible and drivable. Nissan’s Intelligent Key system includes a clever backup plan, giving you time to replace the battery without interrupting your day.
Accessing and Starting Your Nissan with a Dead Key Fob Battery
Before we dive into battery sizes, let’s address the immediate concern: how to get into your Nissan when the key fob battery is dead. Nissan Intelligent Key fobs are designed with a mechanical emergency key hidden inside. Here’s how to use it:
- Locate the Release: On the back of your key fob, find a small button or latch. Press and hold it to release the emergency key.
- Extract the Emergency Key: Slide or pull the emergency key out from the bottom of the fob.
- Unlock Manually: Use the physical key to unlock your Nissan door, just like a traditional car key.
- Starting Your Vehicle: Once inside, look for a key fob port in your vehicle. This is often located on the steering column or dashboard.
- With a Key Fob Port: Insert the key fob into the port. Then, press the brake pedal (or clutch for manual transmissions) and push the START/STOP button.
- Without a Key Fob Port: If there’s no port, press the brake pedal (or clutch) and hold your key fob firmly against the START/STOP button. This allows the car to detect the fob’s signal even with a weak battery.
If you encounter any difficulties accessing or starting your Nissan using these methods, it’s always best to seek professional assistance. Contact a certified Nissan service center for expert help.
Determining the Correct Nissan Key Fob Battery Size
Now, let’s get to the core question: what size battery does your Nissan key fob need? The battery type can differ based on your Nissan model and the year it was manufactured. Here are the most reliable ways to determine the correct battery size:
-
Check Your Owner’s Manual: Your Nissan owner’s manual is your first and most authoritative resource. Locate the section on key fob battery replacement. It should clearly specify the exact battery type and size required for your key fob.
-
Open the Key Fob and Inspect the Old Battery: This is a foolproof method. Carefully open your Nissan key fob (instructions provided below). Once open, you’ll see the battery. The battery itself will have markings indicating its type. Common markings include CR2025 or CR2032. These are both 3V lithium coin cell batteries, but they differ slightly in thickness.
-
Common Nissan Key Fob Battery Sizes: While it’s always best to verify, many Nissan models use either a CR2025 battery or a CR2032 battery. Generally:
- CR2025: Slightly thinner and may be found in older or slimmer key fob designs.
- CR2032: Slightly thicker and often used in newer or more robust key fobs.
Using the wrong size can prevent the fob from closing properly or making good electrical contact. Always ensure you replace it with the exact specified battery type.
-
Online Battery Finders: Some online retailers specializing in batteries have battery finder tools. You can input your Nissan model and year, and they may suggest the likely battery type for your key fob. However, always cross-reference this information with your owner’s manual or the battery itself.
You can purchase replacement batteries at most drugstores, hardware stores, auto parts stores, and online retailers. For convenience, you can also get them from your local Nissan dealership’s parts center.
Step-by-Step Guide to Changing Your Nissan Key Fob Battery
Once you have the correct size battery for your Nissan key fob, the replacement process is quick and easy. 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.
-
Pry Open the Fob: Carefully insert a small flathead screwdriver or a similar thin, flat tool into the notch along the seam of the key fob. Gently twist or pry to separate the two halves of the fob casing. Avoid using excessive force to prevent damage.
-
Remove the Old Battery: Once the fob is open, you’ll see the battery. Note its orientation (positive side up or down) before removing it. You might be able to gently pry it out with your small screwdriver or use your fingernail.
-
Insert the New Battery: Place the new battery into the battery compartment, ensuring it’s in the correct orientation (matching the orientation of the old battery). It should snap or fit snugly into place.
-
Reassemble the Key Fob: Carefully align the two halves of the key fob casing and press them firmly together until they click securely back into place.
-
Replace the Emergency Key: Slide the emergency key back into its slot until it clicks and is securely held in place.
-
Test Your Key Fob: Press the buttons on your key fob to test if it’s working correctly. The doors should lock and unlock, and the panic button should function.

Nissan Key Fob Reprogramming: When is it Needed?

- Replacing a Lost Key Fob: If you’ve lost a key fob and obtained a new one, it will need to be programmed to your vehicle.
- System Malfunctions: In rare cases, electronic glitches might necessitate reprogramming.
Nissan recommends visiting a dealership for key fob reprogramming. It’s a complex process that requires specialized equipment to ensure security and proper function. Contact Tom Wood Auto Group if you suspect your Nissan key fob needs reprogramming.
