Step-by-Step Guide to Replacing the Battery

Step 1: Locate the Slot

First, locate the small slot at the top of the key fob. This slot is designed for opening the fob.

Step 2: Open the Key Fob

Insert the flathead screwdriver into the slot and gently twist it. This will create a separation on the side of the key fob. Continue twisting and working your way down until the entire fob comes apart.

Step 3: Remove the Circuit Board

Once the key fob is open, you may find that the circuit board comes out. Don’t worry; you can easily put it back together later.

Step 4: Remove the Old Battery

Use the flathead screwdriver to push the old CR2032 battery out of place. Once it’s loose, you can remove it with your fingers.

Step 5: Insert the New Battery

Take your new CR2032 battery and make sure the positive side, which has the battery information, is facing up. Slide it under the metal piece until it clicks into place.

Step 6: Reassemble the Key Fob

If the circuit board has come apart, place it back into the rubber holder with the battery facing up. Ensure the buttons are positioned correctly. Carefully place the trunk key back into its slot and make sure everything lies flush.

Step 7: Close the Key Fob

Once everything is in place, click the key fob back together. The light on the key fob should come on, indicating that the battery is correctly positioned and has power.

Common Issues and Troubleshooting

Sometimes, things might not go as smoothly as planned. Here are some common issues and how to troubleshoot them:
