Locate the small slot on the side of your key fob. This slot is usually near the key ring.
Insert the flat-head screwdriver into the slot and gently pry open the key fob. Be careful not to damage the plastic casing. You might hear a slight click as the casing separates.
Identify the old battery. It will be a small, round, silver disc, likely a CR2025. Note the orientation of the battery – which side is facing up (+) is crucial for proper installation.
Carefully remove the old battery. You can use your screwdriver or fingernail to gently pry it out.
Insert the new CR2025 battery into the key fob. Ensure the positive (+) side faces the same direction as the old battery. Press it firmly into place.
Close the key fob casing. Align the two halves and press them together until they click shut.
Test your key fob. Try locking and unlocking your car to confirm the new battery is working correctly.
