Automobile: Subaru Security Light Flashing Car Won’t Start

Why is the Subaru Security Light Flashing?

The Subaru security light, also known as the immobilizer light, is a flashing indicator signifying that the car’s security system has been activated. This is usually caused by a malfunctioning key or transponder chip in the ignition switch. In order to deactivate the immobilizer and get your car started, you must first identify why the light is flashing and then take steps to resolve the issue.

Common reasons for a flashing security light include a faulty key, transponder chip, or wiring issue. If your key is damaged or worn out, it may not be sending an appropriate signal to your car’s on-board computer. In this case, you will need to replace your key in order to disable the immobilizer and get your car running again.

If your key appears to be functioning correctly but the security light continues to flash, then there may be an issue with your transponder chip. This small device is implanted inside of your ignition switch and works to send a signal from the key up to the vehicle’s computer system. If this chip is damaged or has become disconnected from its wiring harness, then it will not send an appropriate signal and you will need to have it replaced by a qualified mechanic in order for your car to start again.

Finally, if neither of these solutions resolves your issue then there may be an issue with either the wiring or components of your car’s security system itself. In this case it is best to have a professional inspect and diagnose what needs repair in order for you to get back on the road again safely and securely.

What Are The Causes Of A Car Not Starting?

There are many potential causes of a car not starting properly. These can range from simple issues such as low battery charge or clogged fuel filters all the way up to more complex problems such as faulty starter motors or issues with electrical wiring systems. The most common causes of this type of problem include:

  • Dead Battery: A dead battery can prevent even brand new cars from starting properly due to lack of power needed for essential components like starters and fuel pumps.
  • Faulty Starter Motor: The starter motor can fail due either physical damage or wear-and-tear which prevents it from turning over properly.
  • Fuel System Issues: Faulty fuel pumps, dirty fuel filters or clogged fuel lines can prevent fuel from reaching its intended destination.
  • Ignition System Problems: If any part of your ignition system has become faulty then this can prevent spark plugs from igniting correctly.
  • Electrical Wiring Issues: Corroded wiring can create shorts which can prevent essential components like sensors and relays from working correctly.
  • Clogged Air Filter:
    A clogged air filter prevents air flow into an engine which reduces power output causing difficulty starting.
  • Blown Fuses: Fuses are responsible for controlling current flow throughout various circuits within vehicles; if any fuse has blown then this can stop certain components from working correctly.
  • < strong >Malfunctioning Alternator: The alternator helps charge a battery while running; if this component fails then it will reduce battery charge leading to difficulty starting.
