Is your car key fob acting up? Do you have to press the unlock button multiple times to get a response from your vehicle? It might be a sign that your key fob battery is dying and needs replacing. Luckily, replacing your key fob battery is a straightforward task that you can often handle yourself, and the first step is knowing Where Can I Buy A Key Fob Battery.
This guide will walk you through everything you need to know about finding the right replacement battery for your car key fob. We’ll cover the types of batteries key fobs use, where you can purchase them, and even provide a simple DIY guide to replacing the battery yourself.
Understanding Your Key Fob Battery Needs
Before you rush out to buy a new battery, it’s helpful to understand a few key things about key fob batteries. Most car key fobs are powered by small, round batteries known as coin cell or button batteries. The most common type is the CR2032 battery, a 3-volt lithium battery that offers a good balance of power and lifespan for compact devices like key fobs.
However, not all key fobs use the CR2032. Depending on your car’s make, model, and year, your key fob might require a different size, such as CR2025, CR2016, CR2450, or even less common types. Some vehicles, like certain Honda CR-V models, might use a CR1250 battery, while others, like Ford Mustang key fobs, can take two batteries.
Signs that your key fob battery is getting weak include:
- Reduced Range: You need to be closer to your car than usual for the fob to work.
- Intermittent Operation: The fob works sometimes but not others.
- Multiple Button Presses: You have to press buttons repeatedly for the car to respond.
- Dashboard Warning Light: Some cars display a warning message on the dashboard indicating a low key fob battery.
Where Can I Buy a Key Fob Battery? Top Retail Locations
Now, let’s answer the crucial question: where can i buy a key fob battery? The good news is that these batteries are widely available. You don’t necessarily need to go to a dealership or specialized automotive shop right away. Here are several convenient places to find key fob batteries:
-
Drugstores and Pharmacies: Big chains like Walgreens, CVS, and Rite Aid, as well as local pharmacies, typically stock a selection of coin cell batteries, including the common CR2032 and similar sizes. This is often the most easily accessible option for many people.
-
Supermarkets and Grocery Stores: Many supermarkets, especially larger ones with general merchandise sections, carry batteries. Check the electronics or household goods aisles for key fob battery replacements. Stores like Walmart and Target are reliable options.
-

DIY Key Fob Battery Replacement: A Simple Guide
Once you’ve sourced your replacement battery, you can often replace it yourself with a few simple tools. Here’s a step-by-step guide based on expert recommendations:
Tools You’ll Need:
- Thin Blade or Watch Knife: For gently prying open the key fob case.
- Replacement Battery: Ensure you have the correct size (check your owner’s manual or the old battery if possible). CR2032 is common, but verify.
- Precision Screwdriver: Small Phillips head screwdrivers (around 1.4mm to 2.4mm) may be needed for some fobs with screws.
- Tweezers: To handle the small battery.
- Phone Camera (Optional but Recommended): To take pictures as you disassemble the fob, aiding in reassembly.
Steps to Replace Your Key Fob Battery:
-
Open the Key Fob Casing: Carefully inspect your key fob. Some have small screws you’ll need to remove with a precision screwdriver. Others simply snap together. For snap-together cases, use a thin blade or watch knife to gently wedge into the seam and pry the case open. Work your way around the case fasteners gradually, like peeling an orange, to avoid damage. Do not force it open, as this could break the case.
-
Expose the Battery: Once open, you’ll see the internal components. Take a photo with your phone at this stage for reference during reassembly. Locate the battery. It’s usually held in place by clips or a small housing.
-
Remove the Old Battery: Use tweezers or your fingertip to carefully remove the old battery. Note the orientation of the battery – which side is facing up (+ or -). This is crucial for correct installation of the new battery.
-
Insert the New Battery: Place the new battery into the compartment, ensuring the correct orientation (+ side up or down as noted during removal). Make sure it’s securely seated in the holder.
-
Reassemble the Key Fob: Carefully snap the key fob case back together. If there were screws, replace and tighten them gently. Ensure the case is fully closed and secure.
-
Test Your Key Fob: Test the buttons to ensure your car responds correctly. If it works, you’ve successfully replaced your key fob battery!
