Opening the key fob correctly is crucial to avoid damage. Follow these steps to safely access the battery compartment:

2. Locate the Seam: Examine the key fob to find the seam where the two halves of the casing meet.
3. Insert the Screwdriver: Gently insert the tip of your small flathead screwdriver into the seam.
4. Twist and Pry: Carefully twist the screwdriver to start separating the two halves of the fob. Work your way around the seam, applying gentle pressure until the fob pops open.
