Solution

1. Preparation

Gather tools: screwdriver set, multimeter, OBD-II scanner, and a replacement key fob battery if needed.
Ensure the vehicle is in park and turn off the ignition.
Disconnect the negative battery terminal to eliminate electrical hazards.

2. Key Fob Battery Replacement

Remove the key fob cover using a small flathead screwdriver to access the battery compartment.
Take out the old battery and replace it with a new CR2032 battery, ensuring the positive side is facing up.
Reassemble the key fob and test the trunk release function.

3. Inspecting and Testing Trunk Release Switches

Remove the interior panel covering the trunk release switch using a screwdriver.
Disconnect the switch connector and test for continuity with a multimeter. Replace the switch if it shows no continuity.
Reconnect the switch and reassemble the panel.

4. Fuse Inspection

Locate the fuse box under the dashboard or in the engine compartment (refer to the owner’s manual for exact location).
Identify the fuse for the trunk release using the fuse diagram.
Remove the fuse and inspect it. If it is blown, replace it with a new fuse of the same amperage (typically 10A).
Reassemble the fuse box cover.

5. Wiring Inspection

Inspect the wiring harness leading to the trunk release mechanism for frays, corrosion, or disconnections.
If damage is found, repair or replace the affected wiring harness as necessary.
Reconnect any loose connectors and ensure all connections are secure.

6. Reconnect Battery and Test

Reconnect the negative battery terminal.
Test the trunk release from both the key fob and interior switch to ensure functionality.
