Solution

1. Preparation

Gather required tools and parts.
Ensure the vehicle is in a safe, well-ventilated area.
Disconnect the negative battery terminal to avoid electrical shorts during repairs.

2. Check Battery Installation

Sub-steps:
1. Reconnect the positive terminal first, ensuring a snug fit.
2. Reconnect the negative terminal, ensuring it is tight and free of corrosion.
3. Use a multimeter to confirm battery voltage; should read around 12.6 volts or higher.

3. Inspect Electrical Connections

Sub-steps:
1. Visually inspect battery cables for any signs of wear or damage.
2. Clean any corrosion off the terminals using a wire brush and a solution of baking soda and water.
3. Tighten any loose connectors, ensuring there is no movement.

4. Test Ignition System

Sub-steps:
1. Locate the fuse box and check the ignition fuse with a multimeter; replace if blown.
2. Test the ignition relay by swapping it with a similar relay in the fuse box (if available).
3. If necessary, remove the starter motor and bench test it with jumper cables.

5. Verify Key Fob Functionality

Sub-steps:
1. Replace the battery in the key fob if it is low or dead.
2. Test the fob by pressing the unlock button and confirming it responds.
3. If using a push-button start, ensure the fob is inside the vehicle and within range.
