But the first question that comes to mind is: Where Can I Buy A Battery For My Key Fob?

DIY Key Fob Battery Replacement: Is It Right for You?
Many car owners are surprised to learn that they can replace their key fob battery at home. Gone are the days of exclusively relying on dealerships for every car maintenance need. Replacing a key fob battery is typically a straightforward process that requires minimal tools and technical expertise. In most cases, you’ll only need a small flathead screwdriver or a similar prying tool, and of course, a new battery.
However, if you’re not comfortable with DIY tasks or prefer professional assistance, there are always options available. Dealerships and auto repair shops can certainly handle this service for you. Even battery specialty stores, like Interstate All Battery Center, offer key fob battery replacement services. The choice depends on your comfort level, time constraints, and budget. But for those looking to save money and gain a little DIY satisfaction, replacing the key fob battery yourself is definitely worth considering.
Essential Tools for Key Fob Battery Replacement
Before you start your search for “where can i buy a battery for my key fob,” it’s wise to gather the necessary tools. Luckily, you probably already have most of these items around your house. Here’s a quick checklist:
- A Thin Blade or Pry Tool: A watch knife, a small flathead screwdriver from a precision screwdriver set, or even a guitar pick can work to gently pry open the key fob casing.
- Replacement Battery: This is the most crucial item! Key fobs typically use coin cell batteries. The most common type is the CR2032, but it’s essential to verify the correct size for your specific key fob (more on this below).
- Precision Screwdriver (Potentially): While not always necessary, some key fobs use tiny screws to secure the case. A small Phillips head or flathead screwdriver from a precision set (around 1.4mm to 2.4mm) might be needed.
- Tweezers (Optional): Tweezers can be helpful for removing and inserting the small battery, especially in tight spaces.
- Your Smartphone: This is surprisingly useful! Use your phone’s camera to take pictures as you disassemble the key fob. This will serve as a visual guide when you reassemble everything, ensuring you put all the parts back in their correct positions.

Step-by-Step Guide to Replacing Your Key Fob Battery
Once you’ve gathered your tools and found out where can i buy a battery for my key fob, the replacement process is quite simple. Here’s a step-by-step guide to follow:
-
Open the Key Fob Casing: Carefully inspect your key fob for any visible screws. If you see screws, remove them with the appropriate precision screwdriver. If there are no screws, look for a small notch or seam on the side of the fob. This is where you’ll insert your pry tool. Gently wedge your thin blade or screwdriver into the notch and twist or pry to separate the two halves of the case. Work your tool around the seam, gently popping open the fasteners. Avoid forcing it, as you could damage the case.
-
Identify the Battery: Once the case is open, you’ll see the circuit board and the battery. Take a moment to note the battery’s orientation (positive side up or down) and its type. Often, the battery type (like CR2032) is printed directly on the battery itself. This is crucial information when you go to buy a battery for your key fob.
-
Remove the Old Battery: Some batteries are held in place by clips or a small metal arm. Gently unclip or slide any retainers and carefully remove the old battery. Tweezers can be helpful here.
-
Insert the New Battery: Take your new key fob battery and insert it into the compartment, ensuring the correct orientation (match the positive and negative sides to how the old battery was positioned). Make sure the battery is securely seated.
-
Reassemble the Key Fob: Carefully align the two halves of the key fob case and snap them back together. If you removed screws earlier, replace and tighten them. Ensure the case is fully closed and secure.
-
Test Your Key Fob: Try locking and unlocking your car doors with the key fob to ensure the new battery is working correctly.

Where Can I Buy a Battery for My Key Fob? Your Buying Options
Now for the most important question: where can i buy a battery for my key fob? Fortunately, key fob batteries are readily available at numerous locations, both online and in physical stores. Here are some of the most convenient options:
-
Retail Stores: Drugstores, supermarkets, and general retailers like Walmart and Target all commonly stock coin cell batteries like the CR2032 and other sizes used in key fobs. These are often located in the battery aisle, electronics section, or near the checkout. This is often the quickest and easiest option if you need a battery immediately.
-
Auto Parts Stores: Stores like AutoZone, Advance Auto Parts, and O’Reilly Auto Parts are excellent places to buy a battery for your key fob. They carry a wide selection of car-related batteries, including key fob batteries. The staff at these stores are also typically knowledgeable about car parts and can help you find the correct battery if you’re unsure.
-
Battery Specialty Stores: For the widest selection and expert advice, consider battery specialty stores like Interstate All Battery Center. These stores focus exclusively on batteries and often have a vast inventory of less common battery sizes, ensuring you’ll find the exact battery you need for your key fob. They also often offer key fob battery replacement services if you prefer professional help.
-
Online Retailers: Amazon, eBay, and other online retailers offer a vast selection of key fob batteries at competitive prices. Shopping online provides convenience and allows you to easily compare prices and read reviews. However, you’ll need to factor in shipping time if you need the battery urgently.
-
Dealerships (Less Recommended for Just Batteries): While dealerships sell key fob batteries and offer replacement services, they are generally the most expensive option for just buying a battery. Dealerships are better suited for more complex key fob issues or replacements, rather than simple battery swaps.
