What You Need

• Flathead screwdriver

Step-by-Step Instructions

Step 1: Remove the Internal Key

First, locate the button on your key fob. Press and hold this button while pulling out the internal key. This key is used for manual entry into your car.

Step 2: Open the Key Fob

With the internal key removed, you’ll see a keyhole and an indentation above it. Insert a flathead screwdriver into this indentation.

Gently twist the screwdriver to start separating the two halves of the key fob. You may need to work your way around the edges to fully open it.

Step 3: Remove the Old Battery

Once the key fob is open, you’ll see the battery. Use the same flathead screwdriver to carefully lift the old battery out. You can do this by coming in from the side and gently prying it up.

Step 4: Insert the New Battery

Take your new CR2032 battery and make sure the positive side is facing down. Place it into the battery compartment and press it down until it clicks into place.

Step 5: Reassemble the Key Fob

Click the two halves of the key fob back together. Make sure they are securely snapped into place.

Finally, reinsert the internal key back into its slot. Your key fob should now be working with the new battery.
