How often have you been driving your Nissan and realized that the Key Fob battery was dead? It's not an uncommon occurrence. If the key fob has a dead or dying battery, it can be annoying to replace this component.

When it comes to vehicle maintenance, there are a million and one things that need to be done. One of these is replacing the battery in your Nissan key fob. Luckily for you, we have prepared this handy guide so you can do it with ease. Follow our easy steps below, and you will be on your way to enjoying the freedom of opening your car doors with just a click of a button.

How to replace the battery in a Nissan Key Fob?

We all know that it can be frustrating when our Nissan key fob's battery dies. But, there are different ways to keep your car running smoothly and safely for as long as possible.

If you find yourself unable to start the engine or unlock the doors, then the battery in your key fob may be the answer to your problems.

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.

What battery does a Nissan key fob use?

The battery in your Nissan Key Fob is a CR2032 Lithium coin cell. These batteries are easy to find in many places, including Amazon that sells the exact one you'll need for around five dollars or less. What's nice about this particular model of battery is that it has a long life span – sometimes up to five years, depending on usage. However, once the battery starts to wear down, you'll experience issues with your key fob not being able to unlock or lock your car. The best way to make sure that this doesn't happen is by replacing the battery when necessary.

How to start the Nissan with a dead key fob battery?

If the battery of your Nissan key fob is dead, you can still start the car so that you aren't stranded waiting for roadside assistance. Place the fob in the key fob port and touch the brake or clutch as you press the START/STOP button on a Nissan vehicle with a key fob port. Even if your Nissan doesn't have a port, you can still do this. As you step down on the brake, press the key fob against the START/STOP button.

Conclusion

Replacing the battery in a Nissan Key Fob is simple and straightforward. If you followed the instructions in your owner's manual, then there is nothing else to worry about.

If you've never replaced a fob battery before, then it can be intimidating and confusing at first glance. The steps above have helped you so you can feel confident in doing this replacement process yourself without worrying about getting stuck or making mistakes along the way.

Replacing the battery in your Nissan Key Fob is very important so that you can continue using all of its features without any trouble.
