Owning a 2018 Nissan Armada means enjoying the blend of power and luxury this SUV offers. But even the most powerful vehicles rely on a small, often overlooked component: the key fob battery. If you’ve been experiencing issues with your key fob’s range or responsiveness, it might be time for a quick battery swap. So, what size battery does a 2018 Nissan Armada key fob take? Let’s dive in.
Identifying Your 2018 Nissan Armada Key Fob
Before heading to the store, it’s crucial to know which battery you need. The 2018 Nissan Armada, like many vehicles, might have different key fob designs depending on the trim level and added features.
Here’s how to determine your key fob type:
- Visual Inspection: Examine your key fob. Does it have a flip-out key, or is the key integrated into the fob itself?
- Button Count: How many buttons are on your key fob (excluding the panic button)? This is another helpful identifier.
Once you’ve determined the type of key fob you have, finding the correct battery is a breeze.

Signs You Need a New Key Fob Battery
Beyond simply not working, several signs indicate your key fob battery is running low:

- Intermittent Functioning: The key fob works sometimes but not others.
- Warning Light: Some Nissan Armadas might display a warning light on the dashboard if the key fob battery is low.
Beyond the Battery: Other Key Fob Issues
While a dead battery is the most common cause of key fob problems, other issues could be at play:
- Programming Issues: Your key fob might need to be reprogrammed to communicate with your vehicle.
- Antenna Problems: A faulty antenna in your car or key fob can disrupt the signal.
- Internal Damage: Physical damage to your key fob, like dropping it in water, can impact its functionality.
If replacing the battery doesn’t resolve your key fob issues, it’s best to consult a qualified automotive locksmith or your Nissan dealership for further diagnosis and repair.
