During a freezing Michigan morning last winter, I hopped into my 2022 Silverado, pressed the start button… nothing. The key fob was completely dead and I was already late for work. Ten bucks and two minutes later I had it working again and learned it’s literally the easiest fix on the whole truck. If your Silverado remote suddenly stops unlocking doors from across the parking lot or you have to touch the fob to the start button to get it going, you’re just one tiny battery away from being back to normal.
Key Takeaways: Grab a CR2032 battery, flip the fob over, pop out the metal key, slide a flat tool into the little slot on the side to split the case, lift the old battery out with your fingernail or plastic pry tool, drop the new CR2032 in with the + side facing up, snap the case shut, press any button a couple times to wake it up, and you’re done—no programming needed on 2019-2025 Silverado fobs.
Spotting the Exact Moment Your Silverado Fob is Dying
Your Chevy key fob doesn’t just quit overnight; it gives you fair warning. First you’ll notice you have to stand closer to the truck for the locks to work. Then the “No Remote Detected” message pops up on the dash even when the fob is in your pocket. Some guys ignore it until they’re stuck holding the fob right against the push-start button just to get the truck running. That’s the universe telling you the battery is down to its last few percent.
The cool part? Almost every Silverado from 2014-onward (including the new 2025 models) uses the exact same CR2032 coin battery. I’ve done this on a 2016, a 2021, and my buddy’s brand-new 2024 High Country—same battery, same process. The only difference is some older 2014-2018 fobs have a tiny Phillips screw on the back you might need to loosen first, but 99% of newer ones don’t.
Knowing the warning signs saves you from getting locked out in a Meijer parking lot at 10 p.m. Keep a spare CR2032 in the glovebox and you’ll never sweat it again.
- Shorter range → change soon
- “No Remote Detected” warning → change today
- Have to touch fob to start button → battery is basically dead
Tools You Actually Need (and What You Already Have)
You don’t need a single special tool. Seriously. People overthink this and buy “key fob kits” on Amazon when all you really need is one fingernail or a plastic pry tool (the kind that comes free with phone screen protectors). If you only have a pocket knife or flathead screwdriver, wrap the tip in electrical tape so you don’t scratch the plastic.
The battery itself is a CR2032—costs about a buck each if you buy a 5-pack. Get the name-brand ones (Duracell, Energizer, Panasonic); the cheap gas-station ones die in six months. I keep two spares in the center console and swap them every two years whether they need it or not. Takes longer to find your socks in the morning than to change the battery.
- Plastic pry tool or taped flathead
- Fresh CR2032 (positive + side up!)
- Optional: small Phillips for 2014-2018 fobs
Opening the Fob Without Breaking Anything
Flip the fob over so the Chevy bowtie is facing down. See that little silver metal key? Press the tiny button on the back and pull it out. Now look at the spot where the key was stored—there’s a small notch. Stick your plastic tool (or taped screwdriver) right into that notch and gently twist. The back cover pops off like it was never even on there.
Some people try prying all around the seam and end up with scratches or cracked plastic. Don’t do that. That notch is designed exactly for this job. Once the back is off, you’ll see the round battery just sitting there begging to be replaced. The whole case is held together by little clips, not glue, so it snaps right back when you’re done.
If you hear a scary cracking sound, you’re prying in the wrong spot—go back to the key notch and try again. I’ve opened hundreds of these and never broken one using the notch method.
- Use the hidden key slot notch only
- Twist gently—never force it
- Back cover pops straight off
Removing the Old Battery the Safe Way
The old CR2032 is held in by a tiny metal clip on one side. Push that clip gently toward the center with your fingernail and the battery pops right up. Don’t go digging with metal tools or you can bend the clip and cause connection problems later.
Look at which way the writing faces—that’s the positive side. It must face up on the new battery too. If you install it backward, the fob simply won’t work and you’ll think you got a bad battery when you didn’t. I made that mistake once on my wife’s Traverse and spent ten minutes cursing before I flipped it over.
Toss the old battery in the recycling bin at AutoZone—they take them for free. Takes two seconds and keeps lithium out of landfills.
- Push metal clip gently to release
- Note which side faces up
- Recycle old battery
Installing the New Battery and Testing It Instantly
Drop the fresh CR2032 in with the + side (the side with writing) facing up toward you. You’ll hear the metal clip click back into place. Give the fob a quick button press—most of the time the red LED flashes once to say “I’m alive!”
Now snap the back cover on. Start at one end and press along the seam until you hear all the clips click. Slide the metal emergency key back in until it locks. Walk twenty feet from your Silverado, hit the lock button twice—you should hear the horn beep both times. Then hit unlock and watch the lights flash. If everything works from normal distance, you just saved yourself a trip to the dealer.
If nothing happens, double-check the battery direction first—that fixes 95% of “it’s still dead” complaints.
- + side faces up (writing toward you)
- Press any button—LED should flash
- Test from 30-50 feet away
When You Actually Do Need to Worry (and When You Don’t)
Good news: 2019-2025 Silverado fobs never need reprogramming after a battery change. Just pop the new battery in and you’re done. Even if the battery has been dead for months, the truck recognizes the fob instantly.
The only time you might need the dealer is on some 2014-2018 models if both key fobs die at the same time (super rare). Otherwise, one working fob or even the emergency key blade gets you back on the road. Keep one fresh battery in the truck and you’ll never pay the dealership $100 to do a two-minute job.
- 2019+ = zero programming ever
- Keep one spare battery in glovebox
- Dealer only needed if both fobs lost
Final Thoughts
Changing the battery in your Chevy Silverado key fob is honestly easier than filling the washer fluid. Two minutes, one dollar, zero tools if you have fingernails. Do it the second you notice shorter range and you’ll never get stuck touching the fob to the start button like a caveman again. Throw a couple CR2032s in the console today—you’ll thank yourself the next time your remote decides to take a nap.

Frequently Asked Questions (FAQs)
Is it the same battery for every Silverado year?
Yes, from 2014 all the way to the brand-new 2025 models, Chevy uses the exact same CR2032 coin battery in the flip-key fobs. Even the heavy-duty 2500/3500 trucks and the fancy High Country trims take the identical battery. The only tiny difference is some 2014-2018 fobs have a small screw on the back, but the battery itself never changed.
Can I use a cheaper battery from the dollar store?
You can, but you’ll be doing this again in six months instead of two-plus years. Name-brand CR2032s (Duracell, Energizer, Panasonic) have way better cold-weather performance too—super important when your truck sits outside in a Michigan winter. Spend the extra fifty cents and forget about it for years.
Do I need to reprogram the fob after changing the battery?
Not on any 2019-2025 Silverado. Just put the new battery in, press a button, and the truck instantly recognizes it again. Even if the fob has been dead for six months, it wakes right up. Older 2014-2018 models are the same 99% of the time unless both your fobs die completely at once.
Can I change it with just my hands and no tools?
Totally. Once you pull the metal key out, stick your fingernail in that slot and twist—the case pops open every time. I do it that way in gas station parking lots all the time. Tools just make it a hair easier if you have long nails or cold fingers.
Is it safe to use a metal screwdriver?
Only if you wrap the tip in electrical tape first. Bare metal scratches the plastic super easy and looks terrible after a week. Plastic guitar picks or the little pry tools that come with phone screen protectors work perfectly and never leave a mark.
Do I have to take it to the dealer if it still doesn’t work?
Almost never. Double-check the battery is + side up first—that fixes most “dead” complaints. If that’s right and it still won’t work from distance, try cleaning the battery contacts with a cotton swab and a drop of rubbing alcohol. Dealer only if the fob was dropped in water or physically broken.
Can water damage ruin the fob completely?
It can. If you washed the fob in your jeans or dropped it in a lake, water gets inside and corrodes the circuit board. At that point a new battery won’t help and you’ll need a new fob (about $150-$250 programmed at the dealer). That’s why I never keep mine in my pocket at the beach.
Do I need two working fobs for the truck to start after this?
Nope! Even with a dead fob battery, you can hold the fob right against the push-start button (there’s a little key symbol on it) and the truck will start using the backup antenna. Super handy while you grab a new battery from the parts store.
