Step-by-Step Guide

Step 1: Prepare Your Key Fob

First, locate the buttons on the metal part of your key fob. These buttons are essential for opening the key fob.

Hold down both buttons simultaneously and pull out the key. This will reveal additional buttons underneath.

Step 2: Access the Battery Compartment

After removing the key, you will see two more buttons, one on each side of the fob. Press down both buttons.

While holding these buttons, pull on the bottom part of the key fob and wiggle it slightly. The bottom piece should come off, giving you access to the battery compartment.

Step 3: Remove the Old Battery

Once the bottom part is removed, you can easily take out the old battery. Make sure to note the orientation of the battery, as this will be important when inserting the new one.

Step 4: Insert the New Battery

Take your new CR2032 battery and ensure the positive side is facing down. Place the battery into the compartment.

Make sure it is securely in place before proceeding to the next step.

Step 5: Reassemble the Key Fob

With the buttons facing up, slide the bottom piece back into place. Ensure the battery remains facing down during this process.

Click the bottom part all the way down until it is secure. Finally, reattach the key by sliding it back into its original position.
