As a Nissan owner, there’s a common moment of slight panic we all face: pressing the unlock button on your key fob and… nothing. It’s a scenario that can throw a wrench into your day, but thankfully, it’s usually a simple fix. More often than not, a dead battery is the culprit. But what kind of battery does a Nissan key fob take? And what do you do in the meantime?
At Tom Wood Auto Group, we understand the ins and outs of Nissan vehicles, including those handy intelligent key fobs. This guide will walk you through everything you need to know about your Nissan key fob battery, from identifying the right type to replacing it yourself, and even what to do if you’re stuck with a dead fob right now.
Getting Into Your Nissan When the Key Fob Battery is Dead
Before we dive into battery types, let’s address the immediate concern: you’re locked out! Don’t worry, Nissan’s Intelligent Key system is designed for this. Even with a completely dead battery, you can still access and start your Nissan. Here’s how:
- Locate the Emergency Key: Every Nissan key fob contains a mechanical emergency key. Look for a small release button or latch on the back or bottom of your fob. Press and hold this to slide out the emergency key.
- Unlock Your Nissan Manually: Use the emergency key just like a traditional car key to unlock your driver’s side door.
- Starting Your Nissan: Once inside, starting your car depends on whether you have a key fob port or a push-button start:
- With a Key Fob Port: Insert the key fob into the designated port (usually located on the steering column or dashboard). Then, press the brake pedal (or clutch for manual transmissions) and press the START/STOP button.
- Without a Key Fob Port: If you don’t have a port, step on the brake pedal (or clutch) and firmly press the Nissan key fob directly against the START/STOP button. This allows the car to detect the fob’s signal even with a weak or dead battery.
If you’re still having trouble accessing or starting your Nissan, don’t hesitate to contact us at Tom Wood Auto Group for expert assistance.
Identifying the Right Battery for Your Nissan Key Fob
Now, let’s get to the core question: what kind of battery does your Nissan key fob require? The most common types are coin cell batteries, specifically the CR2025 and CR2032 3V batteries. However, the exact battery your fob uses can vary depending on your Nissan model and year.
Here are a couple of reliable ways to determine the correct battery for your Nissan key fob:
- Check Your Owner’s Manual: Your Nissan owner’s manual is a treasure trove of information! Look in the index or the section on keys and remote entry. It should specify the exact battery type required for your key fob.
- Open Your Key Fob and Inspect the Old Battery: This is the most foolproof method. Before heading to the store, take a moment to open your key fob. We’ll walk through the steps in the next section. Once open, you can easily see the battery type printed directly on the old battery itself. It will be clearly marked with letters and numbers like “CR2025” or “CR2032”.
- Consult Our Parts Center: If you prefer to be absolutely sure or want to purchase a battery directly from us, our auto parts center at Tom Wood Auto Group can quickly identify the correct battery for your specific Nissan key fob.

Step-by-Step Guide: Replacing Your Nissan Key Fob Battery
Replacing your Nissan key fob battery is a straightforward DIY task that can save you time and money. Here’s a simple 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 Key Fob: Carefully inspect the key fob casing for a small notch or seam line, usually running along the edge where the front and back halves meet. Insert a small flathead screwdriver or a similar thin, flat tool into this notch. Gently twist or pry to separate the two halves of the key fob. Be careful not to apply excessive force to avoid damaging the casing.
- Remove the Old Battery: Once open, you’ll see the battery. Note the battery’s orientation (+ side up or down) for correct installation of the new battery. Gently pry out the old battery. A small screwdriver or your fingernail can help.
- 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. Press down firmly to ensure it’s securely seated.
- Reassemble the Key Fob: Align the two halves of the key fob casing and press them firmly together until they snap or click back into place. Ensure there are no gaps and the case is securely closed.
- 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.

Key Fob Reprogramming: When is it Necessary?
In most cases, simply replacing the battery will restore your Nissan key fob to full functionality. Reprogramming is generally NOT required after a battery change. However, reprogramming might be necessary if:
- You replace the key fob itself.
- The key fob malfunctions due to other issues.
Nissan recommends visiting a dealership for key fob reprogramming as it’s a complex process involving the vehicle’s security system. If you suspect your key fob needs reprogramming, contact us at Tom Wood Auto Group to schedule professional service.
