How To Change the Battery in a Chevy Key Fob

If your Chevy key fob stops responding consistently, it's likely that the battery is running low. You don't need to be locked out of your car. Whether you'd like our Victorville Chevrolet team to replace your key fob battery or you'd like to learn how to do it yourself, we've got you covered.

Signs You Need To Replace Your Chevy Key Fob Battery

There are a few warning signs you can watch for before your battery dies completely.

Keep an eye out for the following signals:

• Reduced range: You must be within 20 feet (or less) of the car for it to work.
• Multiple presses: The buttons no longer respond the first time you press them.
• Delayed reaction: The fob works, but it operates more slowly than it used to.
• No response at all: None of the buttons function, and the LED may no longer illuminate.
• Advanced battery age:  Most fob batteries have a service life of three to four years.
• Physical wear: Dropping the fob can misalign terminals or loosen the case.

It's likely time to replace your battery if you're experiencing any of these issues. We'll guide you through the step-by-step process of replacing it.

Chevrolet Key Fob Remote Battery Replacement

If you have a standard Chevy key fob — the kind with physical buttons and a flip-out key blade — you can usually swap the battery out in under five minutes. Most models use a CR2032 3V coin cell battery, but you should check your Chevrolet owner's manual to confirm.

Here's how to replace the battery in a standard key fob:

1. Press the small chrome button to release the mechanical key.
2. Find the small notch along the side of the fob and insert a flathead screwdriver.
3. Twist gently to pop open the case.
4. Take note of the battery's orientation. Snap a picture if needed.
5. Remove the old battery using the screwdriver.
6. Insert the new CR2032 battery in the same orientation.
7. Press the two halves of the fob together until they click into place.

If your key fob is from 2010 to 2016 or if it looks like a flip key, follow these steps instead:

1. Flip out the metal key.
2. Use a flat tool to pry open the back of the fob.
3. Pull out the old battery.
4. Insert the new one, ensuring it is facing the same direction.
5. Snap the back cover into place.

We stock CR2032 batteries at Victorville Chevrolet; if you prefer, we can replace your battery for you.

Chevrolet Smart Keyless Entry Remote Battery Replacement

If your Chevy uses a smart keyless entry system — meaning you can start the engine with the push of a button — you have a more advanced fob. It still uses a CR2032 battery, but the fob's interior is a bit more delicate.

Here's how to replace the battery:

1. Press the release button on the side and pull out the mechanical key.
2. Pry open the fob carefully using the notch and a flathead screwdriver.
3. Remove the old battery.
4. Insert a new CR2032 battery in the same position.
5. Snap the case closed.

Be gentle during each step; smart fobs have more interior components than other fobs. If anything feels loose or out of place, bring it to us, and we'll take care of it. You can contact our team to ensure we have your exact fob in stock or to schedule service.

How To Reprogram Your Chevy Key Fob

If you have replaced the battery or obtained a new key fob, you may need to reprogram it to your vehicle. Some models do this automatically, but others require a few manual steps.

Manual Reprogramming for Older Chevy Models

If your Chevy was manufactured before 2015 (roughly), you may need to manually sync the key fob. Here's how it's done:

1. Unlock your door manually and sit in the driver's seat.
2. Insert your key into the ignition.
3. Hold down the fob's “unlock” button.
4. Turn the key to the “on” position while holding the button, then back to “off.” Do this twice.
5. Release the “unlock” button after you hear the door locks cycle.
6. Press and hold the fob's “lock” and “unlock” buttons simultaneously.
7. Wait for the doors to lock and unlock again.
8. Turn the key to the “on” position to finish.

This process should link the key fob to your vehicle. You can repeat this for additional remotes if needed.

Quick Programming Method for Newer Models

If your Chevy has a push-button start or keyless entry system, it can be paired using a simpler method:

1. Sit in your vehicle with all doors closed.
2. Insert the key and turn it to the “on” position without starting the engine.
3. Press and hold the key fob's “lock” and “unlock” buttons simultaneously for about 15 seconds.
4. Wait for the horn to sound or the door locks to cycle, confirming successful programming.

We can assist you at Victorville Chevrolet if the car doesn't respond or you're unsure which method applies.
