Replacing the Key Fob Battery

To change the battery in your Subaru Outback key fob, you’ll need a few specific tools and some patience. Make sure to follow each step carefully for optimal performance.

Gathering Necessary Tools

First, gather all the tools and materials you will need. You will need a CR2032 button cell battery as the replacement. Keep a small flathead screwdriver or a Phillips screwdriver handy. A clean, flat surface is also useful to keep parts organized and avoid losing pieces.

Having the right tools on hand makes the process smooth and keeps the key fob functioning properly.

Opening the Key Fob

To open the key fob, locate the small silver tab on the back. Press this tab to release and remove the internal key. Using the flathead screwdriver, gently pry apart the two halves of the fob. Be careful not to use too much force to avoid damaging the circuit board inside.

The key fob should open easily if you apply gentle, steady pressure. Make sure to keep track of all the small parts.

Removing the Old Battery

Once the key fob is open, you will see the old battery in place. Use the screwdriver to carefully lift the old battery out of its compartment. Note the position of the positive side of the battery before you remove it. This ensures that you place the new battery correctly.

Dispose of the old battery properly, and make sure the battery compartment is clean before proceeding.

Installing the New Battery

Take your new CR2032 battery and place it in the compartment. Ensure the positive side is facing the correct direction. Align the battery icon on the circuit board with the compartment. This is crucial for the key fob to work as intended.

After placing the new battery, reassemble the two halves of the key fob by pressing them together until they click. Reinsert the internal key, and test the key fob to make sure it is functioning. Check its range and responsiveness to ensure it works properly.

By following these steps, your Subaru Outback key fob should be as good as new.
