Step 1: Remove the Key

First, flip your key fob over. Locate the button at the bottom of the key fob. Hold this button down while you remove the key from the front. This button is a tab that you need to press down to release the key.

Step 2: Open the Key Fob

With the key removed, hold the key fob and locate the bottom tab. Press down on this tab and pull on the key fob. It might require a bit of wiggling, but the whole piece will eventually come out.

After inserting the new battery, slide the piece you removed earlier back into the key fob. Push it all the way down into place. Once it’s secure, reattach the key to the key fob.

Step 6: Test the Key Fob

To ensure you did everything correctly, press a button on the key fob and check for the activation light. If the light turns on, even faintly, it means the battery replacement was successful.
