Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface and turn off the ignition.
Disconnect the vehicle battery to avoid electrical issues during repair.

2. Fuse Inspection and Replacement

Tools Required: Fuse puller or needle-nose pliers.
Locate the fuse box (usually under the dashboard or in the engine compartment).
Identify the fuse for the trunk release (refer to the owner's manual).
Remove the fuse and check if it is blown (a broken filament indicates failure).
If blown, replace it with a new fuse of the same amperage.

3. Key Fob Battery Replacement

Tools Required: Small flathead screwdriver.
Carefully pry open the key fob casing using the screwdriver.
Remove the old battery and replace it with a new, identical battery type.
Reassemble the key fob and test its functionality.

4. Manual Release Mechanism Inspection

Tools Required: Screwdriver set, flashlight.
Remove the inner trim panel in the trunk (carefully pry off clips).
Inspect the manual release lever and cable for any damage or disconnection.
If the cable is loose or disconnected, reattach or replace it as necessary.

5. Trunk Latch Mechanism Repair

Tools Required: Socket set, lubricant (like WD-40), cleaning cloth.
Inspect the trunk latch for obstructions or dirt buildup.
Clean the latch mechanism with a cloth and apply lubricant to ensure smooth operation.
Test the latch by manually operating it to ensure it engages and releases properly.
