Opening the Key Fob Casing:

Locate a small notch or seam on the fob casing. Gently insert your flat-head screwdriver or watch knife into this opening and twist slightly to begin separating the two halves of the fob. Work your way around the seam, gently prying until the case pops open. Avoid using excessive force, which could damage the casing. -
Battery Removal and Replacement:
Once the fob is open, you’ll see the battery. Take a picture with your phone at this stage to remember the battery orientation (+ side up or down). Note how the old battery is positioned before removing it. Some batteries are held in place by small clips or pressure. Use your fingertip or tweezers to carefully remove the old battery. Now, take your new battery and install it in the same orientation as the old one. Ensure it’s securely seated in its compartment. -
Closing the Key Fob:
Carefully align the two halves of the key fob casing and snap them back together. Press firmly until you hear or feel them click into place, ensuring a secure closure. If your fob had screws, re-insert and tighten them gently.
