Solution

1. Preparation

Gather necessary tools and parts.
Disconnect the negative battery cable to ensure safety while working on electrical components.

2. Check and Replace Key Fob Battery

Use a small screwdriver to open the key fob.
Replace the old battery (typically a CR2032) with a new one.
Reassemble the key fob and test the trunk release function.

3. Inspect and Replace the Trunk Release Fuse

Locate the fuse box (typically under the dashboard or in the engine compartment).
Identify the trunk release fuse using the diagram on the fuse box cover.
Remove the fuse using fuse pullers and check for continuity with a multimeter.
Replace with a new fuse of the same amperage if the old one is blown.

4. Test Trunk Release Actuator

Reconnect the negative battery cable.
Access the trunk release actuator (usually located near the latch).
Disconnect the actuator connector and use a multimeter to check for voltage when the trunk release button is pressed.
If there is voltage but no movement, replace the trunk release actuator.

5. Reassemble and Test

Reconnect any disconnected components.
Ensure all screws and covers are secured.
Conduct a test of the trunk release using the key fob and inside button to ensure proper functionality.
