How to Access and Start Your Nissan with a Dead Key Fob Battery
Before diving into what battery for nissan key fob you need, let’s address the immediate issue: getting into your car with a dead fob. Nissan’s Intelligent Key fobs are designed with a clever backup plan. An emergency mechanical key is hidden inside, allowing you to manually unlock your vehicle. Here’s how to use it:
- Locate the small release latch on the back of your Nissan key fob. Press and hold this latch to detach and remove the emergency key, usually found at the base of the fob.
- Use the physical emergency key to unlock your Nissan door, just like a traditional car key.
- Once inside, you’ll need to start your vehicle. Look for a designated key fob port inside your car.
- If your Nissan has a key fob port, insert the entire key fob into the port. Then, press the brake pedal (or clutch for manual transmissions) and press the START/STOP button.
- If you can’t find a key fob port, don’t worry. Simply step on the brake pedal (or clutch) and firmly press the Nissan key fob directly against the START/STOP ignition button.
This method should allow you to start your Nissan and get you on your way, even with a dead key fob battery. However, it’s crucial to replace the battery soon for continued key fob convenience.
Identifying the Correct Battery for Your Nissan Key Fob
Now, let’s get to the core question: what battery for nissan key fob do you need? The battery type can differ depending on your specific Nissan model and the year it was manufactured. The most reliable way to determine the correct battery is to check the dead battery itself.
Once you open your key fob (instructions below), carefully remove the old battery. You’ll find markings on the battery indicating its type. Common batteries used in Nissan Intelligent Key fobs are typically CR2025 or CR2032 3V batteries.
Another helpful resource is your Nissan owner’s manual. This document usually specifies the exact battery type required for your key fob. If you prefer not to open the fob immediately, consulting your manual is a quick way to find out what battery for nissan key fob is needed. You can purchase these batteries at most hardware stores, department stores, or auto parts retailers. Of course, our parts center at Keyfobx.com can also assist you in finding the right battery.
Step-by-Step Guide to Replace Your Nissan Key Fob Battery
Replacing your Nissan key fob battery is a straightforward task you can easily do yourself. Here’s a simple 7-step guide:
- Begin by flipping your Nissan key fob over and pressing the release button. This will allow you to slide out and remove the emergency mechanical key.
- Carefully separate the key fob casing. Locate the small notch along the seam where the front and back halves of the fob meet. Insert a small, flathead screwdriver or a similar thin, flat tool into this notch. Gently twist or pry to begin separating the two halves of the key fob.
- With the key fob open, you’ll see the old battery. Take note of its orientation – how the positive (+) and negative (-) sides are positioned within the casing. Remove the dead battery.
- Insert the new battery, ensuring it is placed in the same orientation as the old one. Double-check the positive and negative markings to ensure correct placement.
- Reassemble the key fob by carefully aligning the front and back halves of the case. Press them firmly together until you hear or feel a click, indicating they are securely closed.
- Slide the emergency mechanical key back into its designated slot in the key fob until it is fully inserted.
- Finally, make sure the emergency key is locked in place by moving the slider button (if applicable to your model) back to its original position.
After these steps, your Nissan key fob should be powered up and ready to use with its new battery.
