Solution

1. Preparation

Gather tools needed: OBD-II scanner, multimeter, screwdriver set, and replacement key fob battery.
Ensure the vehicle is in a secure, flat location.

2. Replace Key Fob Battery

Sub-steps:
- Open the key fob using a small flathead screwdriver to gently pry the halves apart.
- Remove the old battery (CR2032 for most models) and insert a new battery, ensuring the polarity is correct.
- Snap the key fob back together securely.

3. Inspect and Repair Wiring

Sub-steps:
- Locate the trunk latch connector and disconnect it.
- Use a multimeter to check for continuity in the wiring harness.
- If wiring is damaged, repair or replace the damaged section with appropriate gauge wire.
- Reconnect the trunk latch connector securely.

4. Test the Trunk Latch Actuator

Sub-steps:
- Remove the trunk trim panel to access the trunk latch actuator.
- Use a multimeter to check for voltage at the actuator connector while someone presses the remote button.
- If no voltage is present, trace back to the fuse box to check for blown fuses or damaged wiring.
- If voltage is present but the actuator does not operate, replace the actuator.

5. Reassemble and Test

Sub-steps:
- Reinstall the trunk trim panel after completing repairs.
- Ensure all connectors are secure and the wiring is properly routed.
- Test the trunk operation using the remote and the interior button.
