Accessing and Starting Your Nissan with a Dead Key Fob Battery
The brilliance of the Nissan Intelligent Key system lies in its backup plan. Even when the battery is flat, your key fob contains a mechanical emergency key. This allows you to manually unlock your Nissan and get going. Here’s the step-by-step process:
- Locate the Emergency Key: On the back of your Nissan key fob, you’ll find a small release latch or button. Press and hold this to detach and slide out the emergency key, typically found at the base of the fob.
- Manually Unlock Your Door: Use the physical emergency key to unlock your Nissan car door, just like you would with a traditional key. Insert the key into the driver’s side door lock cylinder and turn to unlock.
- Starting Your Nissan: Once inside, starting your Nissan depends on whether you have a dedicated key fob port or a push-to-start system.
- With a Key Fob Port: If your Nissan has a designated key fob port (often located on the steering column or dashboard), insert the key fob into the port. Then, press the brake pedal (or clutch for manual transmissions) and push the START/STOP button.
- Without a Key Fob Port (Push-to-Start): If you don’t have a key fob port, step on the brake pedal (or clutch) and firmly press the Nissan key fob directly against the START/STOP ignition button. This allows the car to detect the key fob’s signal passively, even with a dead battery.
If you encounter any difficulties entering or starting your Nissan using these methods with a presumed dead key fob battery, it’s always best to seek professional assistance. Contact your local Nissan dealership or a trusted automotive service center for guidance.
Identifying the Right Replacement Battery for Your Nissan Key Fob
Knowing the correct battery type is crucial for a successful Nissan key fob battery replacement. The type of battery your Nissan key fob requires can vary depending on the specific model and year of your vehicle. There are a couple of reliable ways to determine the right battery for your Nissan Intelligent Key:
- Check Your Owner’s Manual: Your Nissan owner’s manual is a valuable resource and will specify the exact type of battery required for your key fob. Consult the index or the section on keys and remote entry.
- Open Your Key Fob and Inspect the Old Battery: This is a foolproof method. By carefully opening your key fob (instructions detailed in the next section), you can access the dead battery. The battery itself will have markings – usually a combination of letters and numbers – indicating its type. Common batteries for Nissan key fobs are CR2025 or CR2032 3V batteries.
You can purchase these common coin cell batteries at most drug stores, hardware stores, department stores, and online retailers. For added convenience, your local Nissan parts center will also carry the correct key fob battery for your Nissan.

Step-by-Step Guide: Replacing Your Nissan Key Fob Battery in 7 Easy Steps
Replacing your Nissan key fob battery is a straightforward DIY task that can save you time and money. With your new battery in hand, follow these seven simple steps to get your Nissan Intelligent Key working like new:
- Remove the Emergency Key: Flip your Nissan key fob over. Locate and press the small release button or latch to detach and remove the emergency key. Set the emergency key aside.
- Pry Open the Key Fob Casing: Carefully inspect the key fob casing. You’ll typically find a small notch or seam where the two halves of the fob join. Insert a thin, flathead screwdriver or a similar small, flat tool into this notch. Gently twist or pry to separate the two halves of the key fob casing. 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 old, dead battery. Take note of the battery’s orientation – specifically, which side is facing up (+ or -). This is important for inserting the new battery correctly. Gently remove the old battery. You may be able to pry it out with your small screwdriver or use your fingernail.
- Insert the New Battery: Take your new Key Fob Battery For Nissan (CR2025 or CR2032, as identified earlier) and insert it into the battery compartment. Ensure the battery is placed in the correct orientation, matching the orientation of the old battery you removed. It should usually snap into place.
- Reassemble the Key Fob Casing: Carefully align the two halves of the key fob casing and press them firmly together until they click securely back into place. Ensure there are no gaps and the casing is fully closed.
- Reinsert the Emergency Key: Slide the emergency key back into its slot in the key fob until it clicks or locks into position.
- Test Your Key Fob: Press the buttons on your key fob to test if it’s working. The doors should lock and unlock, and the panic button should function. If everything works as expected, you’ve successfully replaced your Nissan key fob battery!
