2. Inspect and Replace Key Fob Battery

Remove the key fob cover using a small flathead screwdriver.
Replace the old battery with a new one, ensuring proper orientation.
Reassemble the key fob and test the trunk release feature.

3. Access the Trunk Release Mechanism

Remove the interior trunk panel by unscrewing any fasteners and gently prying the panel loose.
Locate the trunk release actuator and inspect for any visible damage or disconnections.

4. Test and Repair Electrical Connections

Using a multimeter, check for voltage at the trunk release actuator when the button is pressed.
If no voltage is detected, trace wiring back to the switch and check for continuity.
Repair any damaged wires or replace the actuator if defective.
