Remove the Valet Key

The first step is to remove the valet key from the key fob. Look on the side of the key fob and depress the valet key release button. Pull the valet key out and set it aside.

Access the Battery Compartment

Next, locate the small indentation on the back of the key fob. Insert the small flat-head screwdriver into this indentation. Wiggle the screwdriver gently to pop off the back cover of the key fob. This will give you access to the battery compartment.

Remove the Old Battery

Once the back cover is off, you will see the old CR2032 battery. Carefully pop the old battery out of its compartment. Note the orientation of the battery so you can insert the new one correctly.

Insert the New Battery

Take your new CR2032 battery and ensure the positive side (marked with a plus sign) is facing up. Place the new battery into the compartment, making sure it fits snugly.

Reassemble the Key Fob

With the new battery in place, it’s time to reassemble the key fob. Align the bottom edge of the back cover with the key fob. Press down on the cover to snap it back into place. Finally, reinsert the valet key into its slot.
