What You’ll Need

Insert the screwdriver or key: Gently insert the flat-head screwdriver or key into the release slot and apply slight pressure.
Separate the key fob halves: Carefully pry the two halves of the key fob apart. You might hear a slight click as they separate. A plastic opening tool can be helpful to avoid scratching the key fob.
