Solution

1. Preparation

Gather tools and parts needed for the repair and ensure the vehicle is parked on a level surface. Disconnect the negative battery terminal to prevent electrical shock.
Tools Required: Multimeter, OBD-II scanner, basic socket set, wire brush (for cleaning), replacement fuses (if needed).

2. Addressing the Battery Issue

Sub-step 1: If the battery voltage is low, charge the 12V battery using a battery charger until it reaches a minimum of 12.4 volts.
Sub-step 2: Clean the battery terminals with a wire brush to remove any corrosion, then reconnect the terminals securely.

3. Fixing Key Fob Issues

Sub-step 1: If the key fob battery is dead, replace it with a new battery (typically CR2032). Follow the manufacturer's instructions for opening the key fob.
Sub-step 2: Reprogram the key fob if necessary, following the vehicle's manual.

4. Replacing Fuses and Relays

Sub-step 1: If any fuses related to the starting system are blown, replace them with fuses of the same amperage. Refer to the owner's manual for fuse ratings.
Sub-step 2: If the starter relay is faulty, replace it with a new relay. Ensure it is seated correctly in the fuse box.

5. Final Checks

Reconnect the negative battery terminal.
Attempt to start the vehicle to see if the problem is resolved.
