Nothing is more frustrating than pressing your Chevy key fob and getting — nothing. Dead key fobs always seem to happen at the worst possible time, like when you’re already running late or it’s pouring rain. But there’s good news. Replacing your Chevrolet key fob battery is surprisingly simple and takes less than five minutes to do.
You don’t need to schedule a dealership appointment or pay someone $50-plus for something you can easily do yourself. At Turan Foley Chevrolet in Gulfport, we’ll help you find out how you can get your key fob working again. If you’re thinking about upgrading to a new model altogether, our new vehicle inventory has plenty of options with the latest key technology.
What Type of Key Fob Do You Have?
First things first. You need to work out what type of key fob you have. Chevrolet has used several designs over the years, but the process is essentially the same. The three most common types are:
- Smart keyless entry remote: This is the latest key fob used in modern Chevrolets with a push-button start.
- Flip key: Popular in models from 2010-2016, such as the Cameo and the Equinox.
- Standard remote: Used in older models such as the Suburban and the Silverado.
What Battery Does My Chevy Key Fob Need?
Most Chevrolet key fobs take a CR2032 3-volt battery, which costs less than $5 online or at any hardware store or pharmacy. However, some newer models may use a CR2450 battery instead. The specific brand doesn’t matter, but make sure you have the right size. If you’re unsure, you can find a diagram under the battery that will tell you which battery you need.
Chevy Key Fob Battery Size
Older Chevy fobs, for the years prior to 2020, use a CR2032 battery. Newer Chevy fobs from 2020 onwards use a CR2450 battery, which is slightly larger and thicker. These batteries are not interchangeable, so make sure you double-check which one your fob needs before you buy a battery.
Tools You’ll Need
The good news is that you don’t need very much to replace the battery for a Chevy key fob. All you need is:
- A small flathead screwdriver (If you have a newer model, you can use the metal key itself instead.)
- A new CR2032 or CR2450 battery
- A clean, flat workspace
That’s all you need. You don’t need any special tools, and this five-minute fix will save you a trip to the dealership.
Step-By-Step Battery Replacement Process
Follow this guide to replace your key fob, depending on the type you have:
Smart Keyless Entry Remote (The Newest Style)
Here’s how to replace the battery with the smart keyless entry remote:
- Press the chrome button on the side of the fob to remove the metal key.
- Use the metal key to pry open the Chevy key fob by inserting it into the slot at the bottom and twisting gently.
- Once you have pulled the two sides apart, remove the dead battery using the screwdriver.
- Insert the new CR2032 or CR2450 battery with the positive (+) side facing down.
- Close the remote and snap the fob back together.
- Slide the key back in.
- Test all buttons to make sure they’re working.
Flip Key (2010-2016 Models)
To replace the battery in a flip key, follow these instructions:
- Push the button to flip the metal key out.
- Pull the back off carefully.
- Replace the battery with the positive side facing down.
- Snap the cover back in place.
- Test the fob on your vehicle.
Standard Remote Key Fob
Here’s how to replace the battery with the standard remote:
- Find the small slot on the side of the key fob.
- Use the screwdriver to pry off the back to separate the two halves.
- Use the screwdriver to pop out the old battery.
- Put the new battery in with the positive side facing up.
- Press the fob halves back together until they click.
- Test the fob on your vehicle.
If you’re experiencing any issues with your Chevrolet vehicle beyond the key fob, you might want to apply for financing on a newer, more reliable model.
Signs You Need To Replace Your Key Fob Battery
Don’t wait until your fob completely dies. Here are the warning signs that you need to replace your battery:
- You need to press buttons multiple times for it to work.
- The fob only works when you’re close to the vehicle.
- The lock or unlock functions work intermittently.
- The range has significantly decreased.
- Your vehicle displays a “key fob battery low” message.
Most Chevy key fob batteries last three or four years with normal use. If yours is dying faster, you might be accidentally pressing buttons in your pocket or purse, which can drain the battery.
Troubleshooting and Tips
If your key fob still isn’t working after replacing the battery, try these fixes:
- Check that you have positioned the battery properly with the positive side facing up or down.
- Clean the battery contacts with a cotton swab.
- Press and hold the lock and unlock buttons together for 15 seconds to reset.
- Make sure you have reassembled the fob properly with no loose parts.
Most Chevrolet key fobs don’t require reprogramming after changing the battery, but if yours still isn’t working, you might need to sync it with your vehicle. The process varies by model year, so check your owner’s manual for specific instructions. Key fobs are just one part of owning a Chevrolet. If you’re thinking about upgrading to a newer model with advanced features, browse our new vehicle inventory to find your perfect match.
