Look at your key fob. See that little slot or notch on the side? That’s your entry point. Insert your fingernail or the flathead screwdriver there and gently pry it open. It’ll pop like a stubborn pickle jar lid. No Hulk strength needed—just a gentle, confident wiggle.
If your fob has a physical key inside (like a flip-out key), slide that sucker out first. It’s usually held by a tiny latch. Don’t panic if the key flies across the room—it’s just testing your ninja reflexes. You’ll find the battery compartment behind or beside where the key lived.
