Finding your key fob battery dying can be incredibly frustrating, especially when you’re in a hurry. Thankfully, getting a replacement is usually quick and straightforward. This guide covers everything you need to know about where to get a key fob battery and what to consider for a smooth replacement.
Common Places to Find Key Fob Batteries
You have several options when it comes to buying a new key fob battery, each offering varying levels of convenience and pricing:
- Auto Parts Stores: Stores like AutoZone, Advance Auto Parts, O’Reilly Auto Parts, and NAPA Auto Parts are excellent places to start. They offer a wide variety of battery brands and types at competitive prices.
- Retail Stores: Big box retailers such as Walmart, Target, and even grocery stores often carry standard key fob batteries in their electronics or automotive sections. This is a convenient option if you need a battery quickly.
- Online Retailers: The internet provides endless choices. Amazon, eBay, and dedicated battery retailers like Batteries Plus Bulbs offer an extensive selection of key fob batteries, often with customer reviews to help you choose.
- Dealerships: While generally the most expensive option, dealerships guarantee compatibility with your specific car model. If you have a rare or high-end vehicle, this might be your best bet.
Identifying the Right Battery for Your Key Fob
Before heading out to purchase a replacement, it’s crucial to know what type of battery your key fob needs:
- Check Your Owner’s Manual: The most reliable source for this information is your car’s owner’s manual. It usually specifies the exact battery model required.
- Look for Markings on the Old Battery: If you can open your key fob (more on that later), the old battery will have markings indicating its type, such as CR2032 or CR2016.
- Consult Online Resources: Many auto parts stores and battery retailers have online tools where you can input your car’s make, model, and year to find compatible batteries.
Opening Your Key Fob and Replacing the Battery
Most key fobs can be opened easily with a flat-head screwdriver or even a coin. Look for a small notch or groove along the edge of the fob.
Here’s a quick rundown of the replacement process:
- Locate the notch and gently pry open the key fob casing.
- Carefully remove the old battery, noting its orientation.
- Insert the new battery, ensuring it matches the old one’s position.
- Snap the casing back together.
- Test all key fob functions to ensure the new battery works correctly.
“Always remember to handle the new battery with care and avoid touching its terminals,” advises John Miller, a seasoned automotive electrician. “This helps preserve battery life and ensures optimal performance.”
