How to Replace Your Key Fob Battery

Learn how to replace the battery in your key fob with Blain’s Farm & Fleet.

A key fob conveniently helps you lock and unlock your vehicle, as well as open your trunk or tailgate. Your key fob might have the key built right into it, or be separate from your car key. Either way, key fobs run on batteries. While you don’t need the key fob battery to start your car, you do need it for any remote functions that come with your vehicle. When the battery becomes weak or dies, you’ll need to replace it. Replacing your key fob battery is pretty simple, and Blain’s Farm & Fleet is here to teach you how to replace your key fob battery.

How to Replace Your Key Fob Battery
If you have a newer car, you most likely have a key fob. Learn how to replace the battery in your key fob with Blain’s Farm & Fleet.

1.  Open Your Key Fob

The first step is to open up your key fob. Take a flat head screwdriver and gently pry it open around the edges. It’s best to pry it open in a few different places so you don’t break the key fob.

2. Pinpoint the Battery Type

If you don’t already know what kind of replacement battery you need, you’ll be able to identify it now that you have the key fob opened up. Pay attention to the battery – and + markings, and the type of battery you’ll need. You can purchase your replacement battery from Blain’s Farm & Fleet.

3. Replace the Battery

Now it’s time to replace the battery. Put the battery in the correct position, aligning properly with the battery markings. Gently snap the fob back together and test the remote buttons to make sure the new battery works.

That’s it! If you’re still unsure about replacing your key fob battery, you can always visit your local Blain’s Farm & Fleet automotive department. For more tips on caring for your vehicle and auto accessories, visit our Automotive blog.
