How To Change A Battery In A Chevy Key Fob?
A dead key fob battery leaves you standing there, pressing buttons that do nothing. The remote won’t lock or unlock your Chevy, and suddenly your morning just got more complicated. You could drive to the dealership, but that’s a hassle and a hit to your wallet.
Most of the time, you can handle this yourself in under five minutes with a tiny coin cell battery. No special tools, no programming, no waiting around. Here’s how to figure out which battery your model needs and where to get a good replacement.
Identifying Your Chevy Key Fob Type
Recommended Products
Chevy has used a couple of different battery sizes over the years, and it matters which one your fob takes. Older remotes usually run on a CR2032, while newer trucks and SUVs moved to a slightly larger CR2450.
If you toss the wrong size in there, it won’t fit or power the fob properly. The easiest thing to do is pop open your current fob and check the number printed on the old battery. That tells you exactly what you’re looking for.
Common Chevy Fob Battery Types
| Vehicle Era | Battery Type | Typical Models |
|---|---|---|
| 1997-2020 | CR2032 | Silverado, Tahoe, Equinox |
| 2021-2026 | CR2450 | New Tahoe, Silverado, Suburban |
| Hybrid/EV | Varies | Bolt, Volt, Hummer EV |
- Open the fob to read the existing battery label.
- Check the fitment guide in product images carefully.
- Note if your vehicle has Passive Entry Passive Start.
- Verify the year and trim level of your Chevy.
- Ensure the new battery voltage matches the old one.
Tools Needed for Safe Replacement
Recommended Products
You don’t need a garage full of tools to do this. A coin or small flathead screwdriver usually does the trick, and some replacement kits even throw in plastic pry tools.
The point is to be gentle, Chevy fobs snap together with plastic clips, and forcing them with something sharp can crack the case.
I’d start by finding something thin and flat to slip into the seam of your key fob. A plastic pry tool works best, but if you don’t have one, wrap the tip of a small flathead in tape to keep from scratching the plastic.
Gently twist near the key ring and work your way around until the clips release. If your fob has a screw (some older models do), remove it first and keep it somewhere safe. Set everything on a clean, flat surface so nothing rolls away.
The actual battery swap is usually quick once the case is open.
Locate the seam or screw on your key fob casing.
Insert a pry tool or coin into the designated slot.
Twist gently to separate the two halves of the fob.
Remove the old battery without touching the contacts.
Reliable Batteries for Your Chevy Remote

Not all coin cell batteries are built the same, and when your key fob is the difference between getting in your car and having a bad day, you want something dependable.
I looked at what Chevy owners are actually using, both CR2032 for older models and CR2450 for newer ones, and picked out a mix of trusted brands and budget-friendly options. Each one lists the specific models it fits, so you’re not guessing.

Key Fob Replacement Batteries for Chevy & GMC, Pack of 2, Check Fit Guide | For Silverado |
If your fob takes a standard CR2032, this two-pack is a straightforward option. It covers a lot of the older Chevy and GMC models like the Silverado and Equinox.
This pack gives you two CR2032 batteries for most pre-2021 Chevy vehicles. It covers a wide range of models like the Malibu, Traverse, and Cruze. The seller asks you to double-check the fitment guide in the images to make sure your fob matches.
That’s worth doing so you don’t end up with a battery that doesn’t fit. The batteries are easy to install yourself, and no programming is needed afterward. It’s the kind of thing you can knock out in a few minutes and skip a trip to the dealer.
These work fine for daily driving and standard key fobs. You get two batteries, so you’ve got a backup ready. One thing to watch is that they don’t cover 2022-2024 Silverado models with PEPS systems, they need a different battery.
If your Chevy falls in the listed years, this is a no-fuss replacement. The packaging isn’t fancy, but the batteries do the job.

Duracell 2032 Lithium Battery, 4 Count, AirTag & Key Fob, CR2032 3V Cell |
Duracell is a name people recognize, and their CR2032 batteries come with a bitter coating to help keep curious kids from swallowing them.
Duracell’s four-pack of CR2032 lithium batteries works with pretty much any device that takes that size, including Chevy key fobs. The bitter coating on both sides is a nice touch for households with small children.
They also claim longer life than some competitors, which means you’re less likely to be popping these open again next year. The batteries maintain steady voltage, so your remote should stay responsive.
If safety around kids matters to you, this is a real plus. The four-count pack also means you’ve got extras for other gadgets or spares. The downside is they cost more per battery than generic options.
But if you’d rather buy once and forget about it, the reliability is worth the extra cost. Just make sure your fob takes a CR2032 before ordering.

Key Fob Replacement Batteries for Chevy & GMC（Silverado Equinox Malibu Traverse Cruze Sier |
This two-pack is another CR2032 option for older Chevys, sourced from suppliers who say they focus on quality control.
You get two lithium CR2032 batteries here, and the listing says they’re compatible with a bunch of Chevy and GMC models like the Silverado, Equinox, and Malibu. They’re supposed to go through quality checks, which should mean more consistent performance than cheap knock-offs.
The seller pushes checking the fitment guide, which is smart, better to confirm now than return them.
For the price, these feel decent. Easy install, no programming. The thing is, they don’t work with 2022-2024 PEPS models. If your fob is from that era, you’ll want to look at CR2450 options instead. Otherwise, if your Chevy is pre-2021 and takes a CR2032, this should work fine.
Just keep an eye on your model year.

Key Fob Battery Replacement for Chevy (Chevrolet) CR2032, Pack of 2 | OEM Remote Replaceme |
This one comes with an install video and OEM-style CR2032 batteries, which is helpful if you’re not sure how to open your fob.
This pack has two OEM-quality CR2032 batteries and an installation video to walk you through it. The video is probably the best part, it shows you how to open your fob without cracking the case. No programming needed, and the batteries are supposed to handle models up to 2024.
The seller also includes a fitment guide, so check your fob against that first.
If you’re the type who’d rather watch something once than figure it out by trial and error, this is a smart pick. The video takes the guesswork out of prying open the case. The batteries themselves are standard CR2032s, so nothing crazy there.
Just keep in mind that 2022-2024 PEPS models aren’t supported. For everything else, it’s a clean swap.

Key Fob Replacement Batteries CR2450 for Chevy & GMC (Check Fit Guide) 2pk |
If your Chevy is a 2021 or newer model, you probably need a CR2450 instead of the standard CR2032.
This two-pack gives you CR2450 batteries, which are the right size for newer Chevy trucks and SUVs like the 2024-2026 Silverado and Tahoe. It also works with the Equinox EV and Hummer EV. The seller’s big warning is to check the fitment images, it won’t work in older CR2032 slots.
That makes sense since the sizes are different.
If you own a late-model Chevy, these are probably what you need. CR2032 batteries won’t fit in newer fobs, so using the wrong size just wastes your time. The install is quick, and there’s no programming required. The pack helps you skip the dealership entirely.
Just make sure your model year is in the compatible range before ordering.

Duracell 2032 Lithium Battery, 2 Count, AirTag & Key Fob, CR2032 3V Cell |
Duracell’s two-pack CR2032 batteries are a step up from generic brands, especially if child safety is a concern.
This two-pack from Duracell has the same bitter coating and child-safe packaging as the four-pack. They work with standard Chevy key fobs that use CR2032 batteries. The bigger claim here is longer-lasting performance, which is backed by their testing against some competitors.
The cells handle temperature swings okay, so winter mornings shouldn’t kill your remote.
If you only need one battery and want the security of a known brand, this is fine. You’re paying more per battery, but the peace of mind is there.
The downside is the smaller pack, you might go through batteries faster if you’ve got multiple vehicles or devices using the same size. Still, for a single fob, you’re covered.

Key Fob Battery Replacement for Chevrolet CR2450, Pack of 2 | Tahoe 2021-2024, Silverado 2 |
This CR2450 two-pack covers specific newer Tahoe and Silverado years, and the seller says it holds voltage well over time.
This kit has two CR2450 batteries for select newer Chevys like the 2021-2024 Tahoe and Silverado. It also works with the 2020-2024 Corvette. The batteries are supposed to hold consistent 3V power for years, which helps with keyless entry systems that need steady voltage.
The pack also points you to install guides, so you’re not figuring it out alone.
Perfect if you’ve got one of the newer Tahoes or Silverados listed. These CR2450 cells are the right move for late-model fobs. Just don’t try using these in older remotes, they’ll be too big. The two-pack is enough for an immediate swap and a backup.
If your model year fits, these are a reliable pick for modern keyless systems.

These CR2032 batteries from SHI say they’ve got a seven-year shelf life, which is handy if you’re buying backups.
This two-pack features SHI Elite CR2032 batteries that list a 2033 use-by date. That means even if you buy them and store them, they should still work when you need them. They say they’re built for a wide range of Chevy and GMC models like the Silverado, Sierra, and Malibu.
The batteries are marketed as industrial-strength, supposedly handling cold weather better than standard ones.
If you like keeping spares around for a while, the long shelf life is a plus. They should last you through at least a couple of fob replacements. Just don’t expect these to work in 2022+ PEPS models, they’re CR2032s, not CR2450s.
For older vehicles, though, they’re solid backups to keep on hand.

Having the pry tool included is the kind of small convenience I’d actually notice. You don’t have to dig around for something to wedge into your fob. These CR2450 batteries are the right call for newer Chevys. Just double-check that your model year and fob shape match the listing.

Key Fob Battery OEM CR2032 Replacement for Chevy & GMC Remote Key (2-Pack) |
This CR2032 two-pack comes with pry tools and video instructions, which makes it easier if you’re new to DIY fob repairs.

Everything you need is in one box, which cuts down on running back and forth to find tools.
If you’d rather have everything together, this is a good bundle. The tools and video take some of the uncertainty out of opening the fob. Just keep in mind these are CR2032s, so they won’t work in newer PEPS models.
If your Chevy is in the listed range, this is a convenient way to handle the replacement without hunting down extra parts.
The biggest thing is matching your battery to your fob. Older Chevys usually take CR2032s, while newer trucks and SUVs need CR2450s. Check your model year and current battery before ordering anything.
If you want extra help opening the fob, kits with pry tools or videos are worth the slight premium. For families, Duracell’s child-safe batteries are a nice touch even if they cost more per unit.
Troubleshooting Common Post-Swap Issues
Recommended Products
Sometimes the remote still won’t work even after you’ve dropped in a fresh battery. Most of the time it’s something simple, maybe the battery isn’t sitting right, or there’s some dirt in the compartment. Here’s how to troubleshoot those little gremlins without pulling your hair out.
Maintaining Remote Longevity
A little care goes a long way with keeping your key fob alive longer. Don’t leave it sweating in your pocket or baking on the dashboard. And while you’re at it, a quick wipe-down every once in a while doesn’t hurt.
- Avoid dropping the fob to prevent internal damage.
- Keep the fob away from direct sunlight heat.
- Replace batteries before they leak corrosive acid.
- Clean the exterior with a soft damp cloth only.
- Do not submerge the fob in water or liquids.
Every now and then, pop open your fob and check for any gunk or corrosion in the battery compartment. You’ll usually spot it as some white powdery stuff, that’s a sign your old battery might’ve leaked.
A quick clean with a cotton swab and a little rubbing alcohol will usually clear it up. Just make sure it’s dry before you put the new battery in. Also, if your buttons are feeling sticky or unresponsive, dirt’s probably built up around them.
A quick wipe with a damp cloth can help. Keep your fob somewhere it won’t get crushed or rubbed raw against your keys.
Replacing your Chevy key fob battery is one of those simple maintenance things that feels annoying until you realize how easy it actually is.
Figure out whether you need a CR2032 or CR2450 based on your model year, grab a reputable battery (and maybe a pry tool if your fob’s stubborn), and take your time seating the battery right. A quick test after closing everything up saves you a second teardown.
Toss a spare in your glove box, and you’re set until next time.
