3. Reassemble the key fob.

3. Inspect Remote Start System Wiring

Sub-steps:
1. Locate the remote start module, which is typically installed under the dashboard or near the fuse box.
2. Visually inspect all wiring harnesses for frays, breaks, or loose connections.
3. Secure any loose connections and repair damaged wires as needed.

4. Check Vehicle Battery Voltage
