Solution

1. Preparation

Gather tools: OBD-II scanner, multimeter, replacement battery.
Ensure the vehicle is parked on a flat surface with the ignition off.

2. Replace Key Fob Battery

Open the key fob using a small flat-blade screwdriver.
Remove the old battery (typically a CR2032 or similar).
Insert the new battery, ensuring the polarity (+/-) matches.
Reassemble the key fob and test the remote start function.

3. Inspect Remote Start Module

Locate the remote start module, usually found near the fuse box or under the dashboard.
Disconnect the module's wiring harness.
Visually inspect for signs of damage (burnt connectors, corrosion).
Use a multimeter to check for continuity in the wires.
If damaged, replace the remote start module with a compatible unit.

4. Reprogram Key Fob (if necessary)

Insert the key into the ignition and turn to the "On" position (not start).
Press the "Lock" button on the remote fob.
Turn the ignition off and remove the key.
Test the remote start function.
