Solution

1. Preparation

Gather tools and parts.
Ensure the vehicle is in a safe area and on a level surface.
Disconnect the negative battery terminal to prevent electrical shock.

2. Battery Inspection and Replacement

Sub-steps:
1. Remove the negative battery terminal followed by the positive terminal.
2. Use a multimeter to check the battery voltage; it should read around 12.6 volts. Replace if below 12.4 volts.
3. Clean the battery terminals with a wire brush if corrosion is present.
4. Reconnect the terminals, starting with the positive, then the negative.

3. Starter Motor and Solenoid Check

Sub-steps:
1. Locate the starter motor (usually near the transmission).
2. Disconnect wiring harness from the starter motor.
3. Use a multimeter to test the voltage at the starter terminal while a helper turns the ignition key to "start."
4. If voltage is present but the starter does not engage, replace the starter motor.

4. Ignition System Inspection

Sub-steps:
1. Inspect the ignition switch for any signs of wear or damage.
2. Test continuity of the ignition switch using a multimeter.
3. Replace the ignition switch if faulty.

5. Immobilizer System Check

Sub-steps:
1. Verify if the key being used is programmed correctly.
2. If the security light is blinking, use a spare key to see if the issue persists.
3. If necessary, consult a dealership or professional to reprogram the key.
