What is RFA and Why Does it Matter?

Before we get to the crux of the issue, let’s start by understanding what RFA actually is. RFA stands for Remote Function Actuation. 

In simpler terms, it’s the technology that allows you to control various functions of your Chevy remotely, such as unlocking doors, starting the engine, and more. 

It works through a combination of your key fob and your vehicle’s onboard computer system.

Now, why is RFA important? It’s all about convenience, really. Having remote access to your car’s functions means you can stay warm in your house while your car warms up, or easily find it in a crowded parking lot with the press of a button. 

It’s one of those features that you might not think about often, but you definitely appreciate when it’s working well.

What is RFA 2 Battery Low Warning?

So, now that you know what RFA is, let’s talk about the RFA 2 Battery Low warning. This message pops up on your dashboard when the battery in your key fob is running low. 

The warning is a helpful reminder to replace the battery before it dies completely, which could leave you stranded without a working key fob.

Now, you might be wondering, “Why does the battery in my key fob even matter? Can’t I just use the physical key?” Well, sure, you could. 

But remember, your key fob does more than just unlock your doors – it’s also responsible for starting your engine and other remote functions. When the battery is low, those functions could be compromised, making your life a little less convenient.

Signs of a Low Key Fob Battery

Besides the obvious RFA 2 Battery Low warning, there are a few other signs that your key fob battery might be on its last legs. These include:

Decreased range

A poor battery can be the cause if you discover that you need to be closer to your car than normal for the key fob to operate.

Inconsistent performance

Low battery capacity may be to blame if your key fob only operates sometimes or if you have to touch buttons more than once for them to take effect.

Failure to start

Even when you use the proper key fob and try to start your Chevrolet, the problem might be a dead battery.

How to Replace Your Key Fob Battery?

The good news is that replacing your key fob battery is a relatively simple and inexpensive process. Here’s a step-by-step guide to help you get it done:

Gather your supplies

You’ll need a small flathead screwdriver, a new battery (check your owner’s manual for the correct type), and a clean workspace.

Open the key fob

Use the screwdriver to gently pry the key fob apart, being careful not to damage the internal components.

Remove the old battery

Once the key fob is open, you should see the battery. Gently remove it, taking note of the orientation of the positive (+) and negative (-) sides.

Insert the new battery

Place the new battery into the key fob, making sure to match the positive (+) and negative (-) sides with the correct orientation.

Close the key fob

Once the new battery is securely in place, carefully snap the two halves of the key fob back together. Make sure the components are properly aligned and that the key fob closes completely.

Test the key fob

After replacing the battery, give your key fob a test run to ensure that it’s working correctly. Try locking and unlocking your doors, starting your engine, and using any other remote functions to confirm everything is in order.

Tips for Key Fob Battery Maintenance

Now that you know how to replace your key fob battery, let’s talk about some tips to help prolong its life and keep it working smoothly:

Avoid extreme temperatures

Excessive heat or cold can negatively affect your key fob battery’s performance. When possible, try to store your keys in a cool, dry place away from direct sunlight.

Limit exposure to moisture

Water and electronics don’t mix, so do your best to keep your key fob dry. If it does get wet, dry it off as soon as possible and avoid using it until it’s completely dry.

Replace the battery regularly

Even if you haven’t received an RFA 2 Battery Low warning, it’s a good idea to replace your key fob battery every few years to ensure optimal performance.

Use high-quality batteries

When it comes to key fob batteries, you get what you pay for. Investing in a reputable brand can help prolong the life of your key fob and reduce the chances of encountering issues.

What if the RFA 2 Battery Low Warning Persists?

In some cases, you might replace your key fob battery and still see the RFA 2 Battery Low warning on your dashboard. If this happens, there are a few possible explanations:

Incorrect battery installation

 Double-check that the new battery is installed correctly, with the positive (+) and negative (-) sides oriented properly.

Damaged key fob

If your key fob has been dropped or otherwise damaged, the internal components might be compromised. In this case, you may need to replace the entire key fob.

Vehicle-related issue

If you’ve ruled out the key fob as the cause of the problem, it’s possible that there’s an issue with your vehicle’s RFA system. In this case, you’ll need to consult your local Chevy dealer or a qualified mechanic for further assistance.


The RFA 2 Battery Low warning on your Chevy is a helpful reminder to maintain your key fob and ensure its proper functioning.
