Locating the Key Fob’s Release Mechanism

Most Toyota key fobs have a small release button or slot. This is usually located on the side or back of the key fob. Pressing this button or inserting the flathead screwdriver into the slot will allow you to separate the two halves of the key fob casing. Be careful not to apply too much force, as this could damage the casing.

Opening the Key Fob Casing

Once you’ve located the release mechanism, gently pry open the key fob casing. You may hear a slight click or pop as the two halves separate. Work your way around the edges of the casing until it is completely open. Be mindful of any small internal components.
