1. Locate the release notch: Look for a small notch or slot on the side of your key fob. This is where you’ll insert your flathead screwdriver.
2. Gently pry open the casing: Carefully insert the screwdriver into the notch and gently twist to separate the two halves of the key fob. Avoid using excessive force, which could damage the casing.
3. Identify the battery: Once the key fob is open, locate the CR2032 battery. It’s usually held in place by a small clip or pressure.
4. Remove the old battery: Use your screwdriver or fingernail to carefully pry the old battery out of its compartment.
5. Install the new battery: Insert the new CR2032 battery, ensuring the positive (+) side is facing upwards, the same way the old battery was positioned.
6. Close the key fob casing: Align the two halves of the casing and press them together until they snap shut.

Common Issues and Troubleshooting

• Check the battery orientation: Ensure the new battery is installed correctly with the positive (+) side facing up.
• Clean the battery contacts: Use a cotton swab and rubbing alcohol to clean the battery contacts inside the key fob. This can resolve connectivity problems.
• Try re-synchronizing the key fob: Consult your owner’s manual for instructions on how to re-synchronize your key fob to your car. This process usually involves a specific sequence of button presses or key turns.
