What Does the Security Indicator Light Mean?

The security indicator light shows that the vehicle has detected a problem. It can be disconcerting when you see the blinking safety light on your dashboard, but once you get the hang of all the lights, you won't be surprised anymore. This article will demonstrate what exactly does this enigmatic symbol signify, and how should you respond when it illuminates.

Understanding the Security Indicator Light on Your Car

Like the other lights on the instrument panel, the security indicator light is designed to warn you about possible problems with the vehicle's security system. Whenever you turn on your vehicle's ignition switch, you will see the light come on. It alerts you to important instructions you missed when you started your car.

If the security light also comes on when the vehicle is not in the ignition or is turned off, this light comes on just to let you know that your car's immobilizer system is working correctly. In short, the purpose of the security light is either to assure you that the anti-theft control system is working correctly or to inform you of any problems with the system.

Security Indicator Meanings of Different Car Models

Different vehicle manufacturers distinguish themselves by designing their security indicators.

Mazda

While driving, if the security indicator light is blinking, it is dangerous to shut off the engine. What you need to do is to visit a Mazda dealer to have it checked. You won't be able to restart the machine if the light is flashing and the engine is turned off.

Nissan

This light will blink when the ignition switch is in the OFF, LOCK, or Auto ACC position. The security systems installed on the car are working correctly, as evidenced by the security indicator light flashing.

Subaru

When the Subaru anti-theft light blinks, it tells you that the car's security system is armed. The security indicator light will blink steadily when the vehicle is locked and off. It will trigger after the engine has been turned off and the key has been removed from the ignition.

Toyota

For Toyota, as soon as the key is removed from the engine switch, this light will flash to let you know the system is on. Once the key is in the engine switch, the light will stop flashing, signaling that the system has been turned off.

Why Does the Security Indicator Light Keep Flashing?

The anti-theft light blinking may relate to many factors.

Battery failure

If your vehicle is parked for an extended period or if you maintain it for a short period, many of its components will begin to deteriorate or become damaged. One of the critical components needed to start and run your vehicle is the battery. Due to undercharging or overuse, the battery may stop working. Due to a faulty battery, the car's security key may be unable to keep track of it, eventually leading to a security light on the dashboard.

Smart key malfunction

Most modern cars are equipped with a remote smart key that you can use to lock or unlock your vehicle from 10 or even 20 meters away. If your car is also equipped with such a key, you may often see a security light. If your car's smart key is not working correctly, in case of damage or lack of power, you may not be able to lock your vehicle after pressing the lock button, which will cause the security indicator light to come on.

Locking or unlocking issues

Another cause of security lights on your car's dashboard is vehicle locking or unlocking issues. This is true for both manual and automatic cars. Whenever you cannot lock or unlock your vehicle correctly, a security light will appear on the dashboard, indicating that this problem exists.

How to Turn Off the Indicator Light

If the security light comes on and you can't turn the car on, don't panic. The solution is simple: try the extra first if you have another spare key. In most cases, the security light indicates that the car no longer recognizes your key so that you can reset the system with another key. All you need to do is insert a second key into the keyhole and start the car with a light twist to turn off the security light.

If the first method doesn't work, try the following. If it still won't start with the second key and the light remains on, you have a couple of options: for example, take your car to the dealer and program a new key for your vehicle, or you can call a mechanic who can help you figure out what the problem is and reprogram the immobilizer system.

Tips for Preventing Security Indicator Light Problems

There are three simple but valuable tips for evading security light problems.

Exam the battery regularly

If the security indicator light is on, check the batteries. The battery may need to be recharged or may be completely drained. Unfortunately, in this case, the car's system will not be able to identify the critical fob's security code and, thus, cannot start the car and turn off the security light. Next, check the connection to the battery. If everything is fine, you can try a restart. The error will likely be corrected. If we match the battery regularly, you can effectively avoid these problems.

Check to prevent damage to your key.

Sometimes, the problem can be with the key itself. When the ignition is turned on, the key's integrated chip sends a code to the security system. The chip must be intact for the key to work. Otherwise, it will not work. Then, the security indicator light will come on. We also need to check the key regularly for signs of wear or damage, which will allow you to use it more smoothly and will not make the security indicator light work.

Daily maintenance of the vehicle

Regular maintenance on your vehicle can help identify early signs of damage in components and extend the lifespan of areas susceptible to wear and tear. While conducting maintenance, ensure that a mechanic tests the connections and functionality of your vehicle's safety indicator system to verify that no issues arise.
