You’re rushing out the door, coffee in one hand, kids yelling in the back, and your Chevy Equinox key fob decides to ghost you. No beep, no lights, nothing. You press the button like it owes you money and… dead silence. Been there? That tiny little battery inside the fob just picked the worst moment to quit. Lucky for you, swapping it takes literally three minutes and costs about three bucks.
Key Takeaways
Grab a CR2032 battery, pop the back of your Equinox key fob open with a small flat tool or the hidden metal key, pull the old battery out with your finger, drop the new one in with the + side facing up, snap it shut, press any button once to wake it up, and you’re done. Whole job is six quick moves.
Spotting the Exact Key Fob You Have
Chevy Equinox key fobs changed a few times between 2018 and 2025. Some have the flip-out metal key, some have the smooth silver Chevy logo on the back, and the newest ones are super thin with no visible seam at first glance. Don’t worry—the battery is always a CR2032 no matter which one you hold.
Look on the back. If you see a small slot or indent near the key ring hole, that’s where the hidden emergency key lives (2018–2022 models). Newer 2023–2025 ones usually have a tiny notch on the side instead. Knowing which style you have saves you from prying the wrong spot and scratching things up.
Flip it over a few times in your hand. You’ll feel a seam that runs all the way around. That seam is your friend—it’s made to pop apart without breaking. I promise Chevy didn’t glue it shut forever.
- Check back for slot or side notch
- Confirm it’s a Chevy bowtie logo (not aftermarket)
- All use the same CR2032 battery
Tools You Really Need (and Nice-to-Haves)
You can do this with stuff already in your kitchen drawer. Absolute minimum: the hidden metal key that’s hiding inside the fob itself or a flat-head screwdriver wrapped in painter’s tape. The tape trick keeps you from leaving ugly marks on the plastic.
I keep a cheap plastic pry tool from my phone repair kit—it’s five bucks on Amazon and never scratches anything. If you’re at work and desperate, even a butter knife with a piece of paper folded over the edge works fine.
Skip metal screwdrivers without protection. One slip and you’ll see a nice shiny scar on your fob forever. Also have the new CR2032 battery ready—buy the name-brand ones (Energizer, Duracell) because the dollar-store ones die in six months.
- Plastic pry tool = safest bet
- Hidden metal key works great
- Tape any metal tool you use
- Fresh CR2032 in your pocket before you start
Finding and Removing the Hidden Metal Key
Most Equinox fobs (2018–2022 especially) hide the metal key inside. Look at the fat end opposite the buttons—there’s a little sliding switch or a tiny release button. Push it and the metal key slides or pops right out.
Newer ones (2023+) sometimes skip the slide and just have a small release you press with your thumbnail. Once the metal key is out, you’ll see a narrow slot. Stick the tip of that metal key straight into the slot and twist gently. The back cover lifts off like magic.
If your fob is the super-slim style with no metal key at all, look along the edge for a tiny notch. Slip your plastic tool or fingernail in there and pop it open the same way. Takes two seconds once you know the spot.
- Slide or press the release
- Pull metal key completely out
- Use the key tip in the slot to pop cover
- No key? Look for side notch instead
Taking the Old Battery Out Without Drama
With the back cover off, the battery is staring right at you. It sits in a little round holder. Gently push the battery to the side with your finger—the holder has a small gap on one edge exactly for this.
The battery will tilt up so you can grab it. Never use metal tweezers or a screwdriver here; the circuit board is super close and you can bend the tiny metal clips that hold the battery in place. Fingers work perfectly 99% of the time.
Look at which way the + sign faced on the old battery. Write it on a sticky note if you’re nervous. Spoiler: the + almost always faces up toward you on Equinox fobs, but checking costs nothing and saves headaches.
- Tilt battery sideways with finger
- Lift straight out—no prying
- Note which side was up (+ symbol)
- Toss dead battery in recycling, not trash
Putting the New Battery In the Right Way
Grab your fresh CR2032. The writing and + symbol go facing UP toward you. Drop it in the round holder and give it a light press with your finger until it clicks flat. You’ll hear or feel a tiny snap.
If it feels loose, you probably have it upside down—flip it and try again. When it’s seated right, the fob lights should flash once or twice all by themselves, like it’s saying “thanks, I’m alive again.”
Close the cover by lining up the clips and pressing until you hear clicks all the way around. No need to slam it—gentle pressure does the job. Then press the lock or unlock button once. Your Equinox should chirp happily in the driveway.
- + side (writing) faces UP
- Light press until it sits flat
- Snap back cover on evenly
- Test immediately—listen for horn beep
Testing and Fixing Common Hiccups
Walk up to your Equinox and hit the lock button. You should hear the doors lock and see the lights flash. Try unlock—same deal. Now try the remote start if you have it. Everything working? High-five yourself; you just saved $100+ the dealer would charge.
Still nothing? Open it again and double-check the battery is + side up. Next, clean the two little metal contacts inside with a cotton swab and a drop of rubbing alcohol—sometimes old battery gunk blocks connection.
Last resort: hold the fob right against the push-button start pad inside the car and press the start button with the fob itself. If the car starts this way, the battery is fine but the fob needs re-syncing (super rare). Drive to the dealer only if that happens.
- Test lock/unlock from 20–30 feet away
- Clean contacts if no response
- Emergency start trick confirms battery is good
- 99% of the time it works first try
Final Thoughts
Changing the key fob battery on your Chevy Equinox is honestly one of the easiest car fixes ever—no tools, no mess, and it works instantly. Keep a couple spare CR2032 batteries in the glovebox and you’ll never get stuck in a parking lot again. Takes longer to read this than to actually do it. Next time your fob acts lazy, smile, grab that battery, and be the hero in three minutes flat.

Frequently Asked Questions (FAQs)
Is it the same battery for every Chevy Equinox year?
Yes, from 2018 all the way to 2025 models, every single Equinox key fob uses the exact same CR2032 coin battery. Even if the fob looks different on the outside, open it up and you’ll see the identical round holder inside. No guessing, no special versions—just grab any CR2032 and you’re golden.
Can I use a cheaper battery from the dollar store?
You can, but I’ve seen those off-brand ones die in four to six months instead of three-plus years. Spend the extra dollar on Energizer or Duracell and you’ll change it way less often. Totally your call, but I keep the good ones in my Amazon subscribe-and-save.
Do I need to reprogram the fob after changing the battery?
Almost never. Just pop the new battery in, close it, and press any button once. The fob wakes right back up talking to your Equinox. I’ve done dozens of these and only once (on a 2018 that sat dead for two years) needed the two-person relearn trick in the owner’s manual.
Is it safe to pry with the metal key?
Totally safe if you’re gentle. The slot is designed exactly for that key tip. Twist easy like opening a paint can, not like you’re mad at it. I do it all the time with zero cracks or damage.
Can the key fob get ruined by water while it’s open?
If you drop the open fob in a puddle, yeah, it can die. But normal kitchen-table battery swaps are fine. Just don’t wash dishes with it open. Quick in-and-out and you’re good.
Do I have to go to the dealer if it still doesn’t work?
Only if the emergency start trick (holding fob to the start button) also fails. That means the fob itself is broken, not the battery. Ninety-nine times out of a hundred the new battery fixes everything.
Is the battery orientation the same on all Equinox fobs?
Yes—plus side (+) and all the writing always face up toward you when the back is off. Chevy kept it consistent across generations. Flip it wrong and nothing happens, so if it stays dead just open it again and turn the battery over.
Can I change it in a parking lot with no tools?
Yep. Use the hidden metal key that’s already inside the fob to pop it open, tip the old battery out onto your hand, slide the new one in from the foil pack with your thumb, snap shut. I’ve done it in a Walmart lot in under two minutes.
