The keyless entrance system goes back to the 1980s, and today it’s hard to imagine owning a car without one. This keyless remote system or key fob uses an RFID to control the entry system of your car, lock it, and protect it from theft. It can also help you locate your vehicle from a distance.

For all these reasons, a key fob that doesn’t work can be a huge inconvenience. This is why in this article, I’ll teach you how to change battery in Nissan key fob in a few easy steps.

What Kind of Battery Does the Nissan Key Fob Use?

The Nissan key fob uses a CR2032 or CR2025 battery. Both are long-lasting, probably lasting for about ten years under normal conditions. They’re also quite affordable, easy to replace, and lightweight. The only difference is that the first one is slightly thicker than the other, so you need to check your user manual to be sure of the specific model.

However, these batteries are non-reusable, so when yours runs out, you have to replace it. Improper storage of the battery can make it run out sooner than expected.

Have you ever been in a hurry, running late, and when you press the entry button on your key fob nothing happens? Don’t worry, because this is not a serious problem. In most cases, your battery is probably dead, and you just need to change it to have your key fob working again as good as new.

Changing the battery is a straightforward process and doesn’t need professional knowledge. Here’s what to do.

  • Flip the key fob to reveal the backside.
  • Unlock the emergency key by moving the slider and remove it.
  • Use a flathead screwdriver to remove the battery, but remember its position.
  • Add the new battery, ensuring that you’re placing it in the same position.
  • Put back the slider and make sure that everything is properly locked.
  • Test the key fob.

Is There Any Other Way To Start The Car Before Replacing the Battery?

If you don’t have a new battery, you can still start your car until you get one. Luckily, there’s an emergency key in your key fob that you can use.

After flipping the key fob, remove the slider to reveal the emergency key. Use this key to unlock the doors.

Depending on your car’s model, it might have a port for the key fob. If it does, tap the brake and press the start button to start your car. If it doesn’t have the port, step on the brake and do the same.

Wrap Up

You can easily replace the battery on your Nissan key fob by following these easy steps. But even if you don’t have a new battery, you can unlock your car using the emergency key.
