Accessing and Starting Your Nissan with a Dead Key Fob Battery
Before we dive into battery types, it’s crucial to know that a dead key fob battery won’t leave you stranded. Nissan Intelligent Key fobs are designed with a clever backup plan. Inside each fob is a mechanical emergency key. Here’s how to use it:
- Locate the Emergency Key: On the back of your Nissan key fob, you’ll find a small release latch or button. Press and hold it to detach and pull out the hidden emergency key.
- Unlock Your Door: Use the physical key to manually unlock your Nissan’s driver-side door, just like you would with a traditional key.
- Starting Your Vehicle: Once inside, the starting process depends on your Nissan model.
- With a Key Fob Port: Some Nissan models have a designated key fob 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 push the START/STOP button.
- Without a Key Fob Port: If you don’t have a key fob port, step on the brake pedal (or clutch) and firmly press the Nissan key fob directly against the START/STOP ignition button.
These methods allow you to start your Nissan even with a completely dead key fob battery, giving you the freedom to drive to a store and get a replacement.
Identifying the Correct Battery Type for Your Nissan Key Fob
Now, let’s get to the core question: what batteries do Nissan key fobs take? The most common types are coin cell batteries, specifically the CR2025 and CR2032 3V lithium batteries. However, the exact battery your Nissan key fob requires can vary depending on the specific model and year of your vehicle.
Here are the most reliable ways to determine the right battery:
- Consult Your Nissan Owner’s Manual: Your owner’s manual is your best resource. Look for the section on “Intelligent Key” or “Key Fob.” It should specify the exact battery type required for your key fob.
- Open Your Key Fob and Check the Old Battery: This is a foolproof method. Follow the battery replacement steps outlined below to carefully open your key fob. Once open, you’ll see the battery compartment. The dead battery itself will have its type clearly printed on it (e.g., CR2025 or CR2032).
- Visual Inspection (Thickness): While both CR2025 and CR2032 batteries are 20mm in diameter, they differ in thickness. CR2025 batteries are 2.5mm thick, while CR2032 batteries are 3.2mm thick. If you have both types available, visually comparing their thickness to your old battery can sometimes help you identify the correct one if the markings are worn off. However, always prioritize checking the markings or your owner’s manual for definitive identification.
Generally, newer Nissan models and more complex key fobs might use the CR2032 for its slightly longer life due to the increased thickness and energy capacity, but CR2025 is also frequently used.

Step-by-Step Guide: Replacing Your Nissan Key Fob Battery
Replacing your Nissan key fob battery is a straightforward DIY task you can accomplish in just minutes. Here’s a step-by-step guide:
- Remove the Emergency Key: Flip your key fob over. Locate and press the release button or latch to detach and remove the emergency mechanical key.
- Pry Open the Key Fob: Carefully inspect your key fob for a small notch or seam running along its edge. This is where you’ll open it. Insert a small, flat-head screwdriver or a plastic pry tool into this notch. Gently twist or pry to separate the two halves of the key fob casing. Avoid using excessive force to prevent damage.
- Remove the Old Battery: Once the key fob is open, you’ll see the battery. Note the orientation of the old battery (positive side up or down). Gently pry out the old battery. A small screwdriver or your fingernail can be helpful here.
- Insert the New Battery: Take your new CR2025 or CR2032 battery (ensuring it’s the correct type!). Install it in the same orientation as the old battery. Usually, the positive (+) side of the battery faces upwards, but double-check the markings inside the key fob case for confirmation.
- Reassemble the Key Fob: Carefully align the two halves of the key fob casing. Press them firmly together until they snap or click securely back into place. Ensure there are no gaps and the casing is properly closed.
- Replace the Emergency Key: Slide the emergency mechanical key back into its slot in the key fob until it clicks and is securely held.
- 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.

- 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.

Frequently Asked Questions About Nissan Key Fob Batteries
Q: What kind of battery does a Nissan key fob typically use?
A: Most Nissan key fobs use a CR2025 or CR2032 3V lithium coin cell battery. The specific type can vary by model and year. Always check your owner’s manual or the markings on the original battery.
Q: Can I use a CR2032 battery if my key fob originally used a CR2025?
A: In many cases, yes. A CR2032 is slightly thicker than a CR2025, but it often fits in key fobs designed for CR2025 batteries. The CR2032 will offer a longer battery life. However, always ensure the battery compartment can properly and securely accommodate the slightly thicker battery without forcing it. If there’s any resistance when closing the key fob, stick with the original CR2025 type.
Q: How long do Nissan key fob batteries last?
A: Nissan key fob batteries typically last for 2 to 3 years, depending on usage frequency and environmental factors.
Q: Is it easy to replace a Nissan key fob battery myself?
A: Yes! As shown in our step-by-step guide, replacing a Nissan key fob battery is a simple process that most owners can do themselves in under 10 minutes.
Q: What happens if my Nissan key fob battery dies while I’m away from home?
A: Don’t worry! As we covered earlier, your Nissan key fob has a hidden mechanical emergency key that allows you to unlock your car and start the engine even with a dead fob battery.
