How To Replace Nissan Leaf Key Battery [6-Steps]

There’s nothing worse than realizing your key fob battery has run out of juice, and you’re left stranded without an emergency key. To prevent this from happening, it’s a good idea to keep a replacement key fob battery in your glovebox for safekeeping.

So, how do you replace your Nissan Leaf key battery once you’ve got your new battery ready? 

According to the Nissan Leaf User Manual, you should follow these steps to change your key fob battery:

1. Take out the metal key and put it to one side. Look for the small button or switch near the keyring on the rear of the key fob. By moving and changing the metal key, it should spring out, allowing you to remove it. If the key fob’s battery dies, you can use this key.

2. Take out the key fob and open it. A little hole or notch should be seen where the metal key used to be lodged. Open the groove using a screwdriver, then gently snap the fob to separate the two sections.

3. Remove the battery from the device. When you peek inside the two parts of the fob, you’ll see a green circuit board on one side and a battery socket on the other. Using a screwdriver, remove the battery. It will come in handy if you are having trouble removing the battery.

4. Put the new battery in place. You’re now ready to replace the battery. The 3 Volt battery is used in the majority of electronic key fobs. However, you can always ask your local Nissan dealer to look into it for you. Place the positive side of the assault face down in the socket of the battery.

5. Return the key fob assembly to its original location. When reassembling the key fob, properly align the two halves or sides of the fob. They must snap back together once you’ve reassembled them. After that, double-check the seams to ensure that everything is in place. Then reinsert the metal key into the slot.

6. Put the key fob through its paces. Everything is now in place and ready to go. Next, you must test your keys to see whether they are working. Finally, stand by your car and use the buttons on the key fob to double-check that the battery is in the right spot.

There could be a problem with your key fob if it isn’t working. You should contact your local Nissan dealer and service center for further information.

What happens when your Nissan Leaf key fob is running low?

You will most likely be unable to start your vehicle if your key fob is damaged. On the other hand, some automobiles and vehicles will start by just pressing the dying key fob into the start button to start the engine.

If your backup key does not start the car, it is not due to a low battery in the key fob. Instead, your keyless entry system is the source of the problem. There could be a problem with your entry system’s computer programming.

It’s simple to figure out how to replace the battery in a Nissan car key. However, you must thoroughly read the instructions and be aware of the correct specifications for your battery. All Nissan models are nearly interchangeable with other vehicle key batteries from various manufacturers.
