How To Replace Nissan Leaf Key Battery

There’s nothing worse than realising 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, once you’ve got your new battery ready, how do you replace your Nissan Leaf key battery? 

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. In the event that the key fob’s battery dies, this key can be used.

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, be sure to 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.

The metal key must then be reinserted into the slot.

6. Put the key fob through its paces. Everything is now in place and ready to go. You must test your keys to see if they are working or not. 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 centre for further information.
