Once the compartment is open, use your screwdriver to pry out the old CR1616 battery. It should pop out with minimal effort.

Step 6: Insert the New Battery

Take your new CR1616 battery and ensure the positive side (with the battery information) is facing down. Push it into place until it sits securely in the compartment.

Step 7: Reassemble the Key Fob

Now, reassemble the key fob by aligning the battery receiver on top of the battery. Click everything back together, ensuring all edges are secure. Test the fob by pressing the buttons to see if the light comes on.

Finally, replace the screw you removed earlier. Twist it back into place with your precision screwdriver. Your key fob should now be fully functional with the new battery installed.
