Have you ever pressed the button on your Nissan key fob and been met with silence? It’s a common inconvenience, and often, the culprit is a dead battery. But don’t worry, gaining access to your Nissan and getting back on the road is usually a straightforward fix. As your trusted auto repair experts at keyfobx.com, we’re here to guide you through everything you need to know about Nissan key fob batteries, focusing on the crucial question: What Battery Goes In A Nissan Key Fob?
This guide will not only answer that question but also provide you with step-by-step instructions on accessing your vehicle with a dead fob, identifying the correct battery, and replacing it yourself. We’ll also cover when it might be time to seek professional help. Let’s dive in and empower you to handle this common car key issue with confidence.
Getting Into Your Nissan When the Key Fob Battery Dies
Before we discuss battery types, let’s address the immediate concern: you’re locked out (or think you are!). A dead key fob battery doesn’t mean you’re stranded. Nissan Intelligent Key fobs are designed with a mechanical backup plan. Here’s how to access your Nissan:
- Locate the Emergency Key: On the back of your Nissan key fob, you’ll find a small release button or latch. Press and hold this to slide out the mechanical emergency key.
- Manually Unlock the Door: Use the emergency key just like a traditional car key to unlock your driver’s side door.
- Starting Your Nissan: Once inside, starting your vehicle depends on whether you have a key fob port or a push-button start system.
- 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 there’s no port, step on the brake or clutch and press the Nissan key fob directly against the START/STOP button. This allows the vehicle to detect the key fob’s signal even with a weak or dead battery.
If you encounter any difficulties entering or starting your Nissan following these steps, it’s always best to contact a professional service technician for assistance.
Identifying the Right Battery for Your Nissan Key Fob
Now, let’s get to the core question: “what battery goes in a Nissan key fob?” The most common types are CR2025 and CR2032 3V lithium batteries. However, the specific battery your Nissan key fob requires can vary depending on the model and year of your vehicle.
Here are the best ways to determine the correct battery:
- Check Your Owner’s Manual: Your Nissan owner’s manual is your best resource. It should specify the exact battery type required for your key fob. Look in the vehicle information or key fob section of the manual.
- Open the Key Fob and Inspect the Old Battery: This is a foolproof method. Carefully open your Nissan key fob (we’ll detail how in the next section) and take out the dead battery. The battery type (e.g., CR2025, CR2032) is clearly printed on the battery itself.
- Consult a Parts Professional: If you’re still unsure, you can contact our parts center or visit a local auto parts store. Provide them with your Nissan model and year, and they can usually identify the correct battery for your key fob.
Both CR2025 and CR2032 batteries are readily available at most drugstores, hardware stores, and online retailers. It’s always a good idea to have a spare battery on hand to avoid future inconveniences.
Step-by-Step Guide: Replacing Your Nissan Key Fob Battery
Replacing your Nissan key fob battery is a simple DIY task that can save you time and money. Here’s a step-by-step guide:
- Remove the Emergency Key: Flip your key fob over and locate the release button. Press it to slide and remove the emergency mechanical key.
- Open the Key Fob Casing: Carefully inspect the key fob for a small notch or slot. Using a small flathead screwdriver or a similar thin, flat tool, gently pry open the key fob at this notch. Be careful not to apply excessive force to avoid damaging the casing.
- Remove the Old Battery: Once the key fob is open, you’ll see the battery. Take note of the battery’s orientation (+ side up or down) before removing it. You can use your fingertip or the tip of a pen to gently pry out the old battery.
- Insert the New Battery: Take your new CR2025 or CR2032 battery (or whichever type is specified for your fob) and insert it into the battery compartment. Ensure the battery is placed in the correct orientation, matching how the old battery was positioned.
- Reassemble the Key Fob: Carefully align the two halves of the key fob casing and press them firmly together until they snap securely back into place. You should hear a click indicating it’s properly closed.
- Replace the Emergency Key: Slide the emergency key back into its slot in the key fob until it clicks and is securely held in place.
- Test Your Key Fob: Press the buttons on your key fob to ensure it’s working correctly. The doors should lock/unlock, and the panic button should function.
If you encounter any issues during this process or your key fob still doesn’t work after replacing the battery, it’s best to seek professional assistance.
When to Seek Professional Help
While battery replacement is usually simple, there are situations where professional help is recommended:
- Key Fob Reprogramming: If you replaced the battery and your key fob still doesn’t work, or if you replaced the key fob itself, it might need reprogramming. Nissan key fob reprogramming is a complex procedure that often requires specialized equipment and should typically be handled by a Nissan dealership or a qualified automotive locksmith.
- Persistent Key Fob Issues: If you’ve replaced the battery and are still experiencing problems with your key fob’s range, intermittent functionality, or other issues, there might be a more complex underlying problem with the key fob itself or your vehicle’s receiver. In these cases, professional diagnosis is recommended.
