It’s a scenario many Nissan drivers have faced: you’re standing at your car, key fob in hand, ready to go, but pressing the buttons yields absolutely no response from your vehicle. If this sounds familiar, the chances are that you’re dealing with a dead battery in your Nissan key fob. Don’t worry, this is a common issue with a straightforward solution. This guide, brought to you by the auto experts at keyfobx.com, will walk you through everything you need to know about Battery For Key Fob Nissan vehicles, from gaining entry to your car with a dead fob to replacing the battery yourself.
Even with a completely dead key fob battery, you can still access and start your Nissan. This ensures you’re not stranded and gives you ample time to obtain a new battery and get your key fob back in working order. Let’s explore how.
Getting into Your Nissan with a Dead Key Fob Battery
The first thing on your mind is likely how to get into your Nissan when the key fob seems unresponsive. Fortunately, Nissan Intelligent Key fobs are designed with a mechanical emergency key hidden inside. This clever feature allows you to manually unlock your car door, even when the electronic functions are out of commission due to a dead battery. Here’s how to find and use this emergency key:
- Accessing the Emergency Key: Locate the small release latch on the back of your Nissan key fob. Press and hold this latch, then gently pull out the emergency key from the bottom of the fob. You should feel it slide out smoothly.
- Unlocking and Starting Your Nissan: Use the physical emergency key to unlock your driver’s side door, just like you would with a traditional car key. Once inside, starting your Nissan depends on whether your vehicle has a designated key fob port.
- With a Key Fob Port: If your Nissan has a key fob port (often located on the steering column or dashboard), insert the key fob into the port. Then, firmly press the brake pedal (or clutch if you have a manual transmission) and press the START/STOP button.
- Without a Key Fob Port: If you can’t find a key fob port, don’t worry. Simply step on the brake pedal (or clutch) and press the Nissan key fob directly against the START/STOP button. The vehicle is designed to detect the key fob even with a dead battery when it’s in close proximity to the start button.
If you encounter any difficulties entering or starting your Nissan following these steps, it’s always a good idea to consult your Nissan owner’s manual or contact a certified Nissan service center for expert guidance.
Identifying the Correct Battery for Your Nissan Key Fob
Knowing what type of battery for key fob Nissan models require is crucial for a successful replacement. The specific battery your Nissan key fob uses can vary depending on the model year and the type of key fob. The most reliable way to determine the correct battery is to physically inspect the old battery after opening the key fob.
Once you open the key fob (instructions in the next section), carefully remove the dead battery. Look closely at both sides of the battery; you should find a code engraved or printed on it. Common battery types for Nissan Intelligent Key fobs are CR2025 or CR2032 3V batteries.
Another resource is your Nissan owner’s manual. It typically lists the specific battery type required for your key fob in the vehicle specifications or key fob section. You can purchase these common batteries at most drug stores, hardware stores, department stores, and online retailers. For your convenience, keyfobx.com also offers a range of replacement batteries compatible with Nissan key fobs.
Step-by-Step Guide: Replacing Your Nissan Key Fob Battery
Replacing the battery for key fob Nissan models use is a simple task you can easily accomplish at home in just a few minutes. Here’s a step-by-step guide to get your key fob working again:
- Remove the Emergency Key: Flip your Nissan key fob over and locate the small release button or latch. Press and hold this button to detach and remove the emergency key.
- Pry Open the Key Fob: Carefully examine the key fob casing. You’ll usually find a small notch or seam line where the two halves of the fob join. Insert a small, flat-head screwdriver or a similar thin, flat tool into this notch. Gently twist or pry to separate the two halves of the key fob. Take your time and avoid applying excessive force to prevent damage to the casing.
- Remove the Old Battery: Once the key fob is open, you’ll see the battery. Take note of the battery’s orientation (positive and negative sides) within the casing. This is important for installing the new battery correctly. Gently remove the old battery. You may be able to pry it out with your fingertip or the same small tool you used to open the fob.
- Insert the New Battery: Take your new CR2025 or CR2032 battery and insert it into the battery compartment, ensuring it’s in the same orientation as the old one you just removed. The positive (+) side of the battery usually faces upwards, but double-check the markings in the casing. Press down firmly to ensure it’s securely seated.
- Reassemble the Key Fob: Carefully align the two halves of the key fob casing. 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 at the bottom of the key fob until it clicks or locks securely.
- 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 as expected.
If your key fob still doesn’t work after replacing the battery, double-check that you’ve installed the battery correctly and that you’re using the right battery type. If issues persist, there may be another problem, and professional assistance might be required.
