Have you ever been stuck outside your Nissan, pressing the key fob buttons repeatedly with no response? A dead key fob battery is a common issue, but luckily, it’s usually a simple fix. Knowing the correct battery type for your Nissan key fob is the first step to getting back on the road quickly. This guide will walk you through identifying the right battery and getting your Nissan key fob working like new again.
You might be surprised to learn that even with a dead battery, you can still access and start your Nissan. Nissan’s Intelligent Key fobs are designed with a mechanical backup plan, giving you time to replace the battery without being stranded.
Accessing Your Nissan with a Dead Key Fob Battery
Before we dive into battery types, let’s quickly cover how to get into your Nissan if your key fob is unresponsive due to a dead battery. Your Nissan Intelligent Key fob contains a hidden emergency key. Here’s how to use it:
- Locate the small release latch on the back of your key fob. Press and hold it to release the emergency key, which you can then slide out from the bottom.
- Use the physical emergency key to manually unlock your Nissan door.
- Once inside, you can still start your vehicle. Look for a key fob port inside your car. If your Nissan has one, insert the key fob into the port, then press the brake pedal or clutch and push the START/STOP button.
- If there’s no key fob port, step on the brake or clutch and press the key fob directly against the START/STOP button. This usually allows the car to detect the key fob and start the engine.
If you encounter any difficulties accessing or starting your Nissan, it’s always a good idea to consult your Nissan owner’s manual or contact a certified Nissan service center for expert assistance.
Identifying the Correct Battery Type for Your Nissan Key Fob
Determining the battery type for your Nissan key fob is crucial for a successful replacement. Nissan key fobs typically use one of two types of batteries: CR2025 or CR2032 3V batteries. The specific battery your key fob requires can depend on the model and year of your Nissan vehicle.
The most reliable way to identify the correct battery type for your Nissan key fob is to open the key fob and examine the old battery. Follow the battery replacement steps outlined below to access the battery compartment. Once you remove the dead battery, you’ll find the battery type printed directly on it. It will be clearly marked with letters and numbers, such as “CR2025” or “CR2032”.
Another method to find out the battery type for your Nissan key fob is to check your Nissan owner’s manual. The manual usually contains specifications for your vehicle’s key fob, including the battery type required. This is a convenient way to check before you even open the key fob.
You can purchase these common batteries at most local stores that sell batteries, including hardware stores, drugstores, and department stores. For convenience, you can also order them online.
Step-by-Step Guide to Nissan Key Fob Battery Replacement
Replacing the battery type for your Nissan key fob is a straightforward process you can do yourself in just a few minutes. Here’s a simple guide:
- Remove the Emergency Key: Flip your Nissan key fob over and press the release button to detach and remove the emergency key.
- Open the Key Fob Casing: Carefully pry open the key fob. Use a small flathead screwdriver or a similar thin, flat tool. Insert it into the notch located between the front and back halves of the key fob and gently twist to separate the case.
- Remove the Old Battery: Once open, carefully take out the dead battery. Take note of the battery’s orientation (positive side up or down) before removing it. This will ensure you insert the new battery correctly.
- Insert the New Battery: Place the new battery of the correct battery type for your Nissan key fob into the battery compartment. Make sure it’s oriented in the same direction as the old one and is securely in place.
- Reassemble the Key Fob: Align the two halves of the key fob case and press them firmly together until they snap or click back into place, ensuring it’s 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: Test the buttons on your key fob to ensure it’s working correctly. The doors should lock and unlock, and the panic button should function.
What If You Can’t Replace the Battery Yourself?
While replacing the battery type for your Nissan key fob is usually easy, if you prefer not to do it yourself, or if you encounter any issues, professional help is available. You can always schedule a service appointment at a Nissan dealership or a qualified auto repair shop. Technicians can quickly replace your key fob battery and ensure everything is working correctly.
Reprogramming Your Nissan Key Fob
In most cases, replacing the battery in your Nissan key fob will not require reprogramming. However, if you are replacing the entire key fob or if your key fob still doesn’t work after a battery replacement, reprogramming might be necessary. Nissan recommends visiting a Nissan dealership for key fob reprogramming, as it often requires specialized equipment to ensure it’s done correctly.
Conclusion
Knowing the correct battery type for your Nissan key fob and how to replace it is a simple yet valuable skill for any Nissan owner. By following these steps, you can keep your key fob functioning and avoid being locked out. Regularly checking your key fob battery can prevent unexpected surprises and ensure you always have easy access to your Nissan vehicle.
