Gently pry open the key fob: Carefully insert the screwdriver into the notch and gently twist to separate the two halves of the key fob. Be careful not to damage the plastic casing.
Find the old battery: Once the key fob is open, you’ll see the old battery. Note its position and orientation.
Remove the old battery: Carefully pry out the old battery. You can use your screwdriver or even your fingernail for this step.
Insert the new battery: Place the new battery into the compartment, ensuring it’s in the same orientation as the old battery.
Snap the key fob back together: Align the two halves of the key fob and press them together until they snap securely shut.
