How do I change the battery in my Chevrolet key fob?

Changing the battery in your Chevy key fob is a simple process that only requires a few minutes and a small screwdriver.

Here are the steps to follow:

  • Find the right type of battery. Chevy key fobs commonly utilize a CR2032 3V coin cell battery, available at the majority of battery retail stores. Make sure you buy a quality brand and check the expiration date on the package.
  • Locate the seam on the side of the key fob. This is where the two halves of the key fob are joined together. You will need to pry them apart with a small flathead screwdriver or a coin. Be careful not to apply too much force or damage the plastic casing.
  • Remove the old battery from the key fob. You may need to use the screwdriver to gently lift it out of its slot. Dispose of the old battery properly and avoid contact with your skin or eyes.
  • Insert the new battery into the key fob. Make sure you align the positive (+) and negative (-) terminals correctly, as shown on the inside of the key fob. Press the battery firmly into place until it snaps in.
  • Reassemble the key fob by snapping the two halves back together. Make sure they are aligned properly and there are no gaps or cracks.
  • Test the key fob by pressing any of the buttons and checking if they work. If not, you may need to reinsert the battery or replace it with another one.

What kind of battery does a Chevy key fob take?

Many electronic devices, including most Chevy key fobs as mentioned earlier, commonly use a CR2032 3V coin cell battery.

However, some models may use different types of batteries, such as CR2025 or CR2016.

To find out what kind of battery your key fob takes, you can check the owner’s manual of your vehicle, look at the label on the back of your key fob, or remove the old battery and see what it says on it.

What happens when your key fob battery dies?

A dead battery in your key fob means it can’t send the signal that your vehicle needs to recognize it and unlock or start.

If your key fob is not working, you may experience some of these symptoms:

  • The buttons on your key fob do not respond or require multiple presses to work.
  • The range of your key fob is reduced or inconsistent.
  • The dashboard indicator light for your key fob flashes or stays on.
  • The vehicle does not detect your key fob when you approach it or try to start it.

Does a dead key fob cause car not to start?

Yes, a dead key fob can cause your car not to start in some cases.

This depends on whether your vehicle has a push-button start system or a traditional ignition switch that requires a physical key.

If your vehicle has a push-button start system, you will need a working key fob to start it.

If your vehicle has a traditional ignition switch, you might be able to use the mechanical key hidden within your key fob to start it.

However, even if you can start your car with a dead key fob, you may not be able to lock or unlock it remotely, which can be inconvenient and unsafe.

Therefore, it is advisable to replace your key fob battery as soon as possible.

Conclusion

A Chevy key fob is a handy device that makes it easier and more convenient to access and operate your vehicle.

However, just like any other battery-powered device, it will eventually exhaust its power and require a replacement.

In this article, we have shown you how to change the battery in your Chevy key fob, what kind of battery you need, and what to do if your key fob dies.
