How to Replace Your Key Fob Battery

1. Open Your Key Fob

The first step is to open up your key fob. Take a flathead 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 above.

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.
