If you’re a Nissan owner, you know that your key fob is an essential part of your daily routine. It allows you to lock and unlock your doors, start your car remotely, and even open your trunk with just a push of a button. But like all electronic devices, key fobs rely on batteries to function correctly.
When your Nissan key fob battery dies, you might find yourself stranded or unable to access your vehicle. Knowing what type of battery your key fob uses and how to replace it can save you time, money, and frustration.
This comprehensive guide will answer the common question: “What Battery Is In A Nissan Key Fob?”, discuss different battery types, and provide step-by-step instructions on how to change the battery yourself.
Nissan Key Fob Batteries: An Overview
Nissan key fobs typically use two types of batteries:
- CR2025: This coin-shaped battery is the most common type found in Nissan key fobs. It’s widely available at auto parts stores, supermarkets, and online retailers.
- CR2032: While less common than the CR2025, some Nissan key fob models may use this slightly larger coin battery. It’s also readily available at most retailers.
Not sure which battery your Nissan key fob uses? Consult your owner’s manual or check for markings on the existing battery inside the fob.
Recognizing a Dying Key Fob Battery
Before you find yourself in a bind, it’s crucial to recognize the signs of a dying key fob battery:
- Decreased range: You might notice that you need to be closer to your vehicle for the key fob to work.
- Intermittent functionality: The key fob might work inconsistently, requiring multiple button presses.
- Warning lights or messages: Some Nissan models display a warning message on the dashboard when the key fob battery is low.
How to Change a Nissan Key Fob Battery: A Step-by-Step Guide
Replacing your Nissan key fob battery is a simple DIY task that you can complete in minutes. Here’s a general guide, but remember to consult your owner’s manual for model-specific instructions:
- Gather your tools: You’ll need a small flat-head screwdriver and a replacement battery (CR2025 or CR2032, depending on your model).
- Open the key fob: Locate the small notch or slot on the fob. Insert the flat-head screwdriver and gently pry open the casing. Be careful not to damage the internal components.
- Remove the old battery: Carefully remove the old battery from its compartment. Note the orientation of the positive (+) and negative (-) sides.
- Install the new battery: Insert the new battery into the compartment, ensuring the positive and negative sides match the original battery’s placement.
- Reassemble the key fob: Align the two halves of the key fob casing and press them together firmly until you hear a click.
- Test the key fob: Ensure all buttons are functioning correctly.
Extending the Life of Your Nissan Key Fob Battery
Here are a few tips to prolong the life of your key fob battery:
- Avoid frequent button presses: While it might be tempting to play with your key fob, unnecessary button presses can drain the battery faster.
- Store your key fob properly: Avoid exposing your key fob to extreme temperatures or moisture, which can damage the battery.
- Replace the battery regularly: Even with careful use, key fob batteries have a limited lifespan. Consider replacing yours every 2-3 years as a preventative measure.
Frequently Asked Questions about Nissan Key Fob Batteries
Q: Can I use any brand of replacement battery?
A: While you can find various brands offering CR2025 and CR2032 batteries, it’s generally recommended to choose reputable brands known for quality and reliability.
Q: What happens if I put the battery in backward?
A: Inserting the battery incorrectly won’t damage the key fob, but it won’t function properly. Always double-check the battery orientation before closing the fob.
Q: Can a dead key fob battery prevent my car from starting?
A: No, a dead key fob battery won’t prevent your car from starting if you have a push-button ignition. You can usually hold the dead fob near the start button or use the hidden mechanical key to start the engine. However, you’ll need a working battery to remotely lock/unlock the doors or use other key fob functions.
