Experiencing a finicky key fob with your 2019 Nissan Altima? Before you schedule a service appointment, a dead key fob battery could be the culprit. Luckily, replacing it is a simple DIY task you can do right at home.

This guide will walk you through the steps to get your key fob back in action and have you smoothly unlocking your Altima in no time.

How to Tell if Your Nissan Altima Key Fob Battery is Dead

A dying key fob usually throws out some warning signs. Keep an eye out for these telltale signs:

Decreased Range: You find yourself having to stand closer to your car for the key fob to work.
Weaker Signal: The car’s response to your key fob commands becomes sluggish or intermittent.
Multiple Presses Needed: You need to press the lock/unlock buttons several times before the car responds.
Key Fob LED Dim: The light on your key fob appears dimmer than usual, even with fresh batteries.

If any of these sound familiar, it’s time for a battery swap.

What You’ll Need to Replace Your 2019 Nissan Altima Key Fob Battery

Before you begin, gather these simple tools:

A fresh CR2032 battery: These are readily available at most grocery stores, auto parts stores, or online.
A small flat-head screwdriver: This is for prying open the key fob casing. You can also use a fingernail or a thin, sturdy object if you don’t have a screwdriver handy.

Now, let’s get your key fob back in tip-top shape:

Locate the release button: On the back of your key fob, find the small, indented button.
Release the mechanical key: Press the release button and gently slide the mechanical key out of the fob.
Separate the key fob halves: Use your flat-head screwdriver (or your chosen tool) to carefully pry open the key fob casing. Start at the notch where the mechanical key was inserted and gently work your way around.
Replace the battery: Inside the casing, you’ll see the CR2032 battery. Carefully remove the old battery and replace it with the new one, ensuring the positive (+) side faces up.
Reassemble the key fob: Align the two halves of the casing and press them firmly together until you hear them snap back into place.
Reinsert the mechanical key: Slide the mechanical key back into its slot on the key fob.

That’s it! You’ve successfully replaced your 2019 Nissan Altima key fob battery.

Testing Your New Key Fob Battery

To make sure everything’s working as it should, test the key fob by locking and unlocking your car a few times. The range and responsiveness should be back to normal.

“It’s surprising how many people put off replacing their key fob batteries,” says John Smith, a seasoned automotive technician at Car Care Central. “A quick battery swap can save you a lot of frustration and potential headaches down the road.”
