Finding the right key fob battery can be surprisingly tricky. Whether your car key has stopped working altogether or is just starting to show signs of weakness, knowing where to buy a replacement battery and how to choose the right one is essential. This guide covers everything you need to know about buying key fob batteries, from the different types available to where you can find them.
Key Fob Battery Types and Where to Find Them
Key fobs use a variety of small, button-cell batteries. Common types include CR2032, CR2025, and CR2016. The specific type required for your key fob is usually printed on the battery itself or in your car’s owner’s manual. Not sure where your owner’s manual is? Check your glove compartment or the car manufacturer’s website. Now, let’s explore some common places to buy these batteries.
Retail Stores: Your Go-To Option for Quick Replacements
Many retail stores stock key fob batteries. Big box stores like Walmart, Target, and Best Buy usually have a wide selection of battery types available. You can also find these batteries at auto parts stores like AutoZone, Advance Auto Parts, and O’Reilly Auto Parts. The benefit of retail stores is the convenience and immediate availability. You can pick up a battery on your way home from work or during your weekend errands.
Online Retailers: A Wider Selection and Potential Savings
Online retailers like Amazon, eBay, and specialized battery websites offer a vast selection of key fob batteries, often at competitive prices. You can compare prices, read reviews, and find hard-to-locate battery types online. However, you’ll need to factor in shipping time. If you need a replacement immediately, online shopping may not be the best option.
Pharmacies and Convenience Stores: A Convenient Stop for Emergencies
Believe it or not, many pharmacies and convenience stores also carry common key fob battery types. These locations are convenient for quick replacements in a pinch, especially if you’re on the go and your key fob dies unexpectedly. However, the selection may be limited compared to larger retailers.
