Locate the release button: On the side of your key fob, you’ll find a small button or switch. This is the key release button.
Release the valet key: Press the release button and slide out the metal valet key.
Use the valet key: Insert the tip of the valet key (or your flathead screwdriver if you prefer) into the small slot on the key fob casing where the valet key was housed. Gently twist the key to pry open the key fob casing. Be careful not to use excessive force, which could damage the casing.
Locate the battery: Once the key fob is open, you should see the CR2032 battery. It’s usually held in place by a small clip or pressure.
Remove the old battery: Carefully pry the old battery out of its compartment using your flathead screwdriver or a plastic pry tool. Avoid puncturing the battery.
Insert the new battery: Place the new CR2032 battery into the compartment, making sure the positive (+) side is facing up, the same way the old battery was positioned.
Reassemble the key fob: Snap the two halves of the key fob casing back together. Make sure it clicks securely shut.
Test the key fob: Try locking and unlocking your car with the key fob to ensure the new battery is working correctly.

Check the battery orientation: Ensure the new battery is inserted correctly with the positive (+) side facing up.
Try a different battery: It’s possible you received a faulty battery. Try replacing it with a brand new one.
Check for damage: Inspect the key fob for any physical damage that might be interfering with its operation.
