Where To Get Key Fob Battery: Your Ultimate Guide to Fast Replacement
There are few things more frustrating than grabbing your car keys only to find your trusty key fob is dead. That terrifying moment of silence when you press the unlock button and nothing happens is enough to ruin your day. Don't worry, getting a replacement battery is usually simple, fast, and inexpensive.
If you're asking yourself, "Where To Get Key Fob Battery", you've come to the right place. We're going to walk you through all the best places—from quick online stops to physical brick-and-mortar stores—so you can get back on the road in minutes.
The good news is that these tiny power sources are widely available. You just need to know which type you need and where to look!
First Things First: Identifying Your Key Fob Battery Type
Before you rush out the door or click "Add to Cart," you absolutely must know the specific battery code your key fob requires. Using the wrong size or voltage can damage your fob or simply won't work.
Most modern key fobs use coin cell batteries, which typically start with "CR." These are flat, circular batteries, and the numbers that follow indicate their dimensions.
Common Key Fob Battery Codes
While various types exist, a few codes dominate the market for modern car keys. If your car is less than ten years old, chances are you need one of these three common types:
- CR2032: This is by far the most common key fob battery. It's used by major manufacturers like Ford, Honda, Toyota, and BMW. It is 20mm in diameter and 3.2mm thick.
- CR2025: Slightly thinner than the 2032, this is also a popular choice, particularly in older or smaller key fobs.
- CR2016: The slimmest of the popular options, often found in smaller, streamlined smart keys.
To find the exact code, you usually need to open the fob itself. Look closely at the existing battery; the code is typically stamped right on the casing. Once you have this code, you are ready to decide where to get key fob battery replacements.
The Online Shopping Route: Convenience at Your Fingertips
If your spare key is working fine and you don't need immediate access to your vehicle, buying batteries online is often the cheapest and most efficient option. Online retailers offer competitive pricing, especially if you buy multi-packs.
Quick Delivery Options for Key Fob Batteries
For most people, online marketplaces are the first logical stop where to get key fob battery replacements. You can usually find major, reputable brands and have them delivered very quickly.
- Amazon: Offers the widest selection, often with Prime next-day or even same-day delivery options. You can easily search for "CR2032 key fob battery" and filter by brand.
- eBay: Great for bulk purchases or hard-to-find older battery models, though delivery times can vary depending on the seller.
- Walmart & Target Online: Both retailers have excellent online storefronts that often allow you to check local stock for immediate pickup, or ship batteries quickly to your home.
When buying online, always stick to well-known brands like Energizer, Duracell, or Panasonic. Cheap, no-name batteries might save you a dollar or two but often have a drastically shorter lifespan.
Physical Retail Stores: Immediate Solutions
If your car is parked somewhere inconvenient and you need that battery *now*, a physical store is your best bet. Thankfully, these coin cell batteries are considered consumer electronics and are stocked almost everywhere.
Big Box Retailers and Grocery Stores
The closest location where to get key fob battery replacements is probably your local supermarket or big box store. They universally carry the most common battery types in the electronics or checkout aisle.
- Walmart / Target: Check the electronics section, often near the small appliance batteries or flashlights.
- Local Grocery Stores (Kroger, Publix, etc.): Look for the battery display near the customer service desk or in the pharmacy section. They typically stock CR2032 and CR2025.
- Drugstores (Walgreens, CVS): These are excellent choices because they often have extended or 24-hour operating times. Their battery sections are usually very easy to find.
Electronics and Specialty Stores (The Best Quality Options)
If you want specialized knowledge or need a less common battery type, head to a store focused on electronics or car parts. These places typically offer higher-grade batteries designed for longevity and reliability.
Auto Parts Stores (AutoZone, O'Reilly, Advance Auto Parts): These stores are a fantastic resource. Not only do they stock the batteries, but sometimes the staff can even help you identify the correct type for your specific vehicle make and model. Furthermore, some locations will replace the battery for you free of charge (though the battery cost still applies).
Hardware Stores (Home Depot, Lowe's): While they focus on tools and materials, most major hardware stores have extensive battery sections that include coin cell types.
Professional Services: When You Need Assistance
What if you can't open your key fob, or perhaps you're worried about damaging the sensitive electronics inside? In this case, letting a professional handle the job might be worth the slightly higher cost.
Dealerships vs. Independent Auto Parts Stores
When seeking professional help, you have a few options, each with different price points and benefits:
- Car Dealerships: They will certainly have the exact, correct battery and replacement process for your specific car. However, this is usually the most expensive route. They often charge a service fee in addition to the battery cost.
- Local Mechanics or Independent Shops: If you already have a trusted mechanic, they can often pop the new battery in quickly during an oil change or inspection. They are generally much cheaper than the dealership.
- Jewelry/Watch Repair Shops: Surprisingly, these shops handle tiny batteries constantly. If you live near a mall, a watch repair kiosk can often replace your key fob battery quickly and correctly, often for a minimal fee.
Installation Tips and What to Avoid
Once you know where to get key fob battery and you have the replacement in hand, the actual installation is usually straightforward, but a few precautions can save you headaches.
When replacing the battery yourself, always use a plastic prying tool or a small flathead screwdriver wrapped in tape. This prevents scratching the plastic casing of the fob.
- Check Polarity: Ensure the positive (+) side of the battery (which usually has the writing on it) is facing the correct direction. Inserting it backward is a common mistake.
- Avoid Touching Contacts: The oil from your skin can degrade battery contacts and reduce the lifespan of the battery. Try to handle the new battery only by the edges.
- Test Immediately: Once the new battery is secured, seal the fob and test it while standing close to your vehicle to ensure the signal is transmitting correctly.
Remember that even if you choose the cheapest replacement option, it is a crucial component for your vehicle security and access. Opting for a quality battery is always worth the minor extra investment.
Conclusion
Finding where to get key fob battery replacements is incredibly easy today, regardless of whether you prioritize convenience, price, or speed. For the best selection and lowest prices, shopping online via Amazon or dedicated battery retailers is ideal. However, if you need immediate power, stop by any local AutoZone, CVS, or large grocery store, as they all reliably stock the common CR2032 and CR2025 cells.
Don't let a dead key fob hold you back. With a little preparation and the correct battery code, you can have your key working like new in just a few minutes, allowing you to lock and unlock your vehicle reliably once again.
Frequently Asked Questions (FAQ)

- Can I use a different size battery if my exact size isn't available?
- No. You should always use the exact battery size specified by the manufacturer (e.g., CR2032). Even a slight variation in thickness (like using a CR2025 instead of a CR2032) can result in a loose connection or prevent the casing from closing properly.

- How long do key fob batteries usually last?
- The lifespan of a typical key fob battery ranges from two to four years, depending on your vehicle model and how often you use the fob. If your key fob stops working frequently, you may need to check the internal circuit board for damage.
- Why are batteries more expensive at dealerships?
- Dealerships typically charge a premium because they offer guaranteed expertise, use OEM (Original Equipment Manufacturer) quality parts, and include a service fee for the labor involved in the replacement process.
