Solution

1. Preparation

Tools Required: Flathead screwdriver, multimeter, replacement fuse (if needed), and new key fob battery.
Disconnect the vehicle battery to ensure safety while working on electrical components.

2. Replace Key Fob Battery

Remove the key fob cover using a flathead screwdriver.
Extract the old battery and replace it with a new one (typically CR2032).
Reassemble the key fob and test the hatch button again.

3. Inspect and Replace Fuse

Locate the fuse box (usually under the dashboard or in the engine bay).
Identify the fuse related to the rear hatch using the fuse diagram.
Remove the fuse using pliers and inspect for continuity. Replace it if it’s blown.
Reconnect the battery and test the rear hatch.

4. Test Rear Hatch Actuator

Reconnect the vehicle battery.
Access the rear hatch actuator, typically located near the latch assembly.
Use a multimeter to check for voltage at the actuator when pressing the key fob button.
If no voltage is present, further investigation into wiring or the body control module may be necessary.

5. Inspect Hatch Latch Mechanism

Check for any debris or obstructions in the latch area.
If the mechanism is stuck, clean it with lubricant and operate it manually.
If damaged, consider replacing the latch assembly.
