The 2022 Stelvio uses a CR2032 coin cell battery in its key fob, and you can replace it yourself in under two minutes without tools or a trip to the dealer
The remote for your 2022 Alfa Romeo Stelvio contains a CR2032 battery, a standard 3-volt coin cell available at any pharmacy, grocery store, or hardware retailer for between $3 and $8. The fob is designed to open without tools — you straightforward slide or pry the two halves apart by hand, swap the old battery for the new one, and snap it back together. The whole job takes longer to find the battery in your junk drawer than to actually do it.
Alfa Romeo does not require you to reprogram the fob after a battery change. Once you close the fob back up, it will work when ready. If it does not, the problem is usually that the battery was inserted upside down (the flat side should face up toward the button) or the contacts inside the fob are dirty.
Key Takeaways
- The 2022 Stelvio key fob uses a CR2032 coin cell battery that costs $3 to $8 and is sold at most stores that have a pharmacy or checkout counter.
- The fob opens by hand — slide your fingernail or a plastic spoon handle into the seam between the two halves and gently pry them apart.
- Insert the new battery with the flat side facing up, toward the button side of the fob, and press the halves back together until they click.
- No reprogramming is needed after a battery swap; the fob will work as soon as you close it.
- If the fob still does not work after replacement, clean the metal contacts inside with a dry cloth and try again.
How to open the Stelvio key fob
Look at the seam that runs around the edge of your fob. You will see a thin line where the two plastic halves meet. Insert your fingernail, a plastic spoon handle, or a plastic pry tool into that seam on the side opposite the Alfa Romeo logo. Do not use a metal screwdriver or knife — you can crack the plastic or damage the contacts inside.
Once you have the tool in the seam, gently twist or pry to separate the halves. The fob will pop open. You do not need to force it; if it is not budging, you are probably in the wrong spot. Try the other side of the seam or rotate the fob 90 degrees and try again.
Removing the old battery and inserting the new one
When the fob is open, you will see the CR2032 battery sitting in a small circular slot. It may be held loosely in place or may fall out when you open the fob — either is normal. Lift out the old battery and set it aside.
Take your new CR2032 battery and look at it. One side is flat and shiny; the other side is slightly raised with a marking or symbol. Insert the battery with the flat side facing up, toward the button side of the fob. This is the most common mistake: if the battery goes in upside down, the fob will not work. Double-check before you close the fob.
Closing the fob and testing it
Align the two halves of the fob so the seams line up evenly. Press them together firmly until you hear or feel a click. The fob should be snug and not rattle when you shake it. If it feels loose, pop it open again and make sure the battery is seated properly in its slot.
Test the fob by pressing the lock and unlock buttons. You should see the lights on your Stelvio respond, and you should hear the locks engage. If nothing happens, open the fob again and check that the battery is inserted with the flat side up. If it is, wipe the metal contacts inside the fob with a clean, dry cloth and try again.
What to do if the fob still does not work
If the fob does not work after you have replaced the battery and checked the orientation, the problem is usually dirty contacts. The metal terminals inside the fob can accumulate dust or corrosion over time, which breaks the electrical connection. Open the fob again and use a clean, dry cloth or a pencil eraser to gently rub the metal contacts on both the battery and the inside of the fob housing. Wipe away any debris, reinsert the battery, and test again.
If the fob still does not respond, the fob itself may be damaged or the battery you purchased may be defective. Try the new battery in another device that uses CR2032 cells (many calculators, scales, or remote controls do) to confirm it works. If it does not, the battery is bad — return it and try a different brand. If the battery works in another device but not in your Stelvio fob, the fob may need to be replaced by an Alfa Romeo dealer.
Where to buy a CR2032 battery
CR2032 batteries are among the most common coin cells in the world and are stocked almost everywhere. Check the pharmacy section of any grocery store, the battery aisle at hardware stores like Home Depot or Lowe's, drugstores like CVS or Walgreens, and big-box retailers like Target or Walmart. You can also order them online from Amazon or eBay. Prices are typically $3 to $8 for a single battery, though buying a pack of four or five is often cheaper per unit.
Avoid extremely cheap batteries from unknown brands. Reputable manufacturers include Energizer, Duracell, Panasonic, and Sony. A name-brand CR2032 will last longer and is less likely to leak inside your fob.
Frequently Asked Questions
Do I need to reprogram my key fob after changing the battery?
No. The 2022 Stelvio fob does not require reprogramming after a battery swap. Once you close the fob, it will work when ready. If it does not, the battery is probably inserted upside down or the contacts are dirty.
What happens if I put the battery in backwards?
The fob will not work. The battery will not make electrical contact if the flat side faces down. Open the fob, flip the battery so the flat side faces up, and close it again. It should work right away.
Can I use a different battery size instead of CR2032?
No. The 2022 Stelvio fob is designed for CR2032 specifically. Other coin cell sizes will not fit properly or will not provide the correct voltage. Always use CR2032.
How often do I need to replace the battery?
A CR2032 battery typically lasts two to four years in a key fob, depending on how often you use it. You will notice the fob becoming less responsive — buttons may require multiple presses — before it stops working entirely. Replace it as soon as you notice a change in performance.
Is it safe to replace the battery myself, or should I go to a dealer?
It is completely safe to replace the battery yourself. The fob contains no dangerous components, and the battery swap takes two minutes. Dealers will perform this service, but they typically charge $50 to $100 for labor on a task you can do at home for $5.
