Solution

1. Preparation

Gather tools: screwdriver set, multimeter, OBD-II scanner, trim removal tools.
Disconnect the battery to ensure safety while working on the electrical components.

2. Inspect and Replace the Key Fob Battery

Open the key fob using a flathead screwdriver.
Replace the old battery with a new CR2032 battery.
Reassemble the key fob and test the rear hatch operation.

3. Check and Replace Fuses

Locate the fuse box, usually found under the dashboard or in the engine compartment.
Identify the fuse for the rear hatch (refer to the owner's manual for the exact location).
Remove the fuse using a fuse puller and inspect it for damage.
Replace with a new fuse of the same amperage if blown.

4. Inspect the Rear Hatch Latch

Remove the interior panel of the rear hatch using trim removal tools.
Visually inspect the latch mechanism for any debris or damage.
Clean the latch with a suitable lubricant and ensure it moves freely.
If damaged, replace the latch assembly by unscrewing it and installing a new one.

5. Testing the Interior Release Button

Connect the multimeter to the connector of the interior release button.
Press the button and check for voltage (should be approximately 12 volts).
If there is no voltage, trace the wiring back to the source for any breaks or damage.
Repair or replace faulty wiring as needed.
