Nissan key fob battery replacement is easy. There are a few things you’ll need for this project. First and foremost, you will need a replacement battery that is compatible with your key fob. You can purchase these batteries online or at the dealership itself, depending on which one works best for your key fob. You can also check the Nissan manual to find the correct battery for your specific model. And then, you will need the help of a small flat head screwdriver to split up the case of your key fob.

The battery replacement procedure below applies to Nissan Altima key fob 2013-2015 model and Nissan Rogue key fob 2019-2021 model.

Step 1: Remove the Nissan key fob’s physical key from the back. This is done by sliding down the small switch at the back of the key fob to remove the physical key.

Step 2: Once the above step is done, flip over to the side where you took the key out from. You will notice a small slot on both tab portions of your key fob. Insert the tip of the flat-head screwdriver into this slot and twist it a bit to split the key fob’s case.

Step 3: You should then be able to see into the casing, where you will find a small silver battery attached to one side of the key fob. You can easily take out the old battery by placing the tip of the screwdriver underneath it to pop off the battery.

Step 4: Insert the new battery by snapping it into place. Make sure that you match the positive and negative sides to ensure your new battery functions properly with your key fob.

Step 5: As soon as the new battery is in place, line up the two halves of the key fob and connect them. Return the physical key fob back to its original position, and your key fob should be ready for use.
