AutoZone sells key fob batteries in most locations

Yes, AutoZone carries key fob batteries. You can find them in the battery section of most AutoZone stores, both in-person and through their website for mail delivery. The selection includes common sizes like CR2032, CR2025, and CR2016 — the coin-cell batteries that fit most car key fobs. Prices typically range from $3 to $8 per battery depending on the brand and type.

AutoZone also offers a battery installation service at many locations. If you bring your key fob into the store, staff can often replace the battery for you while you wait, usually at no extra charge beyond the battery cost. This is useful if you are unsure which battery your fob needs or uncomfortable opening it yourself.

Key Takeaways

  • AutoZone stocks common key fob battery sizes like CR2032, CR2025, and CR2016 at most store locations.
  • You can purchase batteries in-store or order online for delivery or in-store pickup.
  • Many AutoZone locations will install the battery in your key fob for free when you buy it there.
  • If AutoZone does not have your specific battery size in stock, staff can usually order it or direct you to another nearby retailer.
  • Bring your old battery or key fob to the store so staff can confirm the correct replacement size.

How to find the right battery size for your key fob

The easiest way to know which battery you need is to open your key fob and look at the old battery. The size is printed on the flat side — CR2032 is the most common, but some fobs use CR2025, CR2016, or other sizes. If you cannot open the fob yourself, take it to AutoZone and an employee can open it for you to check the size.

If you have lost your key fob or do not have the old battery, you can search online using your car's year, make, and model. Most car manufacturers list the correct battery size in the owner's manual or on their website. You can also call your car dealership with your vehicle identification number (VIN) and they will tell you the exact battery your fob uses.

What to expect when you buy at AutoZone

Walk into any AutoZone store and ask for the key fob battery section. Staff will ask you what size you need or what vehicle you drive. Have your old battery, key fob, or vehicle information ready so they can confirm the right fit. Most stores keep common sizes in stock and can sell you a battery when ready.

If the store is out of stock, AutoZone can order the battery and have it shipped to the store for pickup, usually within a few days. You can also order online at autozone.com, choose in-store pickup, and grab it the same day or next day depending on your location. Shipping to your home is also an option if you prefer not to visit a store.

Installation at AutoZone versus doing it yourself

Most key fob batteries are straightforward to replace yourself. The fob usually has a small slot or button on the edge that lets you pry it open without tools. Once open, you slide out the old battery, note which side faces up, and slide in the new one the same way. The whole process takes less than a minute.

If you are uncomfortable opening the fob or worried about damaging it, AutoZone staff can do this for you. Bring the fob and the new battery to the counter, and they will install it while you wait — usually free of charge. This is especially worth doing if your fob is expensive or if you are not confident handling small electronics.

Other places to buy key fob batteries if AutoZone is not nearby

If you do not have an AutoZone location close by, several other retailers carry key fob batteries. Walmart, Target, and most drugstores stock CR2032 and other common sizes in the battery aisle. Best Buy carries key fob batteries and also offers installation. Home Depot and Lowe's stock batteries as well, though their selection may be smaller.

You can also order key fob batteries online from Amazon, eBay, or directly from your car manufacturer. Online orders usually cost less per battery, especially if you buy in bulk, but you will wait for shipping. For an urgent replacement, a nearby AutoZone, Walmart, or drugstore is usually faster and more convenient.

Cost comparison and battery quality

AutoZone batteries are mid-range in price and quality. A single CR2032 battery at AutoZone costs around $4 to $6, while the same battery at a drugstore might cost $5 to $7. Online retailers like Amazon often sell them cheaper — sometimes $2 to $3 per battery if you buy a pack of four or more. The actual battery inside is usually the same regardless of where you buy it, so price differences are mostly markup.

AutoZone carries both house-brand batteries and name brands like Energizer and Duracell. Name brands tend to last slightly longer and cost a bit more, but for a key fob that you use a few times a day, either type will work fine. Most key fob batteries last two to four years before needing replacement.

What to do if your key fob stops working after a new battery

If you installed a new battery and the fob still does not work, the battery may be installed backwards. Open the fob again and flip the battery so the opposite side faces up. The flat side usually faces down, but some fobs are different — check your owner's manual or look at how the old battery was positioned.

If flipping the battery does not help, the fob itself may be damaged or the contacts inside may be dirty. Try cleaning the metal contacts inside the fob with a dry cloth or a pencil eraser, then reinstall the battery. If the fob still does not work, the problem is likely with the fob's electronics, not the battery, and you may need a replacement fob from your car dealership.

Frequently Asked Questions

Can I use any CR2032 battery in my key fob, or does it have to be a specific brand?

Any CR2032 battery will work in your key fob as long as it is the correct size. Brand does not matter — Energizer, Duracell, AutoZone house brand, and generic batteries all function the same way. The only difference is how long they last, and most last two to four years in a key fob regardless of brand.

Does AutoZone charge for installing a key fob battery?

No, AutoZone does not charge for installation at most locations. You buy the battery and they install it for free while you wait. Call your local store first to confirm, since policies may vary by location, but free installation is standard practice.

What if I do not know what size battery my key fob needs?

Bring your key fob or old battery to AutoZone and staff will identify the correct size for you. If you cannot visit a store, search online for your car's year, make, and model plus "key fob battery size," or call your car dealership with your VIN and they will tell you.

Can I return a key fob battery to AutoZone if it does not work?

Yes, AutoZone accepts returns on batteries within a set timeframe, usually 30 to 60 days with a receipt. If a battery you bought does not work, bring it back to the store with your receipt and they will replace it or refund you. Make sure the battery is not damaged or corroded.

How long does a key fob battery usually last?

Most key fob batteries last two to four years depending on how often you use the fob and the battery brand. Heavy use — pressing the button many times a day — drains the battery faster. When the fob starts to work only at close range or requires multiple presses, it is time to replace the battery.
