Press the key symbol button on the side of the car key; 3. Remove the mechanical key from the car key, insert a flat-head screwdriver into the "open" position, and pry open the car key; 4. Open the car key and locate the battery compartment; 5. Replace the battery; 6. Reassemble the car key; 7. Insert the mechanical key back into the car key.
