Unlock the driver's door with a key (not a key fob). This is important as using the key fob might not properly initiate the anti-theft reset process.
Close all the doors and check that all of them are fully shut.
Insert the key into the ignition switch. Turn the key to the "On" position, where all dashboard lights illuminate, but don't start the engine.
Wait for 10 seconds and then turn the key to the "Off" position. Remove the key from the ignition switch.
Leave the car undisturbed for at least 1 minute, preferably longer, up to 5 minutes. This allows the anti-theft system to fully reset.
After the waiting period, re-insert the key into the ignition switch.
This time, turn the key to the "Start" position to crank the engine and start the vehicle.
If everything goes smoothly, the anti-theft system should be successfully reset, and your vehicle should start without any issues.
However, if the security light still remains on or if the vehicle continues to have issues starting after following these steps, it's best to consult an auto technician or refer to your car's owner's manual for specific instructions related to your vehicle's anti-theft system.
