You’ve just locked your car and noticed a red light blinking on your vehicle. What does it mean, and should you be concerned?
The red light blinking in car after locking makes you question whether everything is as it should be.
In this post, I will delve into the reasons behind this phenomenon and explore possible solutions to put your mind at ease. Let’s get started.
Red Light Blinking In Car After Locking – What Does It Mean?
A red blinking light in car after locking signifies that your vehicle’s security system, notably the immobilizer system, is active and functioning.
This antilight serves as a visual indicator to deter potential thieves.
Modern cars are equipped with advanced security features that include features like immobilizers, alarm systems, and motion sensors.
How Does A Red Light In Car Work?
The security system is activated when you lock your car, either manually or with a key fob.
At that time, the red light in your car starts blinking to indicate that the security light is turned on and actively watching out for any unauthorized entry.
Thus, the flashing red light is a visual deterrent to discourage potential thieves or vandals.
Any attempt to unlock, open, or tamper with the car’s doors, trunk, or hood can trigger the security indicator and active alarms or other security measures.
When you unlock your vehicle using the key or key fob, the system stops working, and the red light typically stops blinking.
It indicates that the system is no longer actively monitoring, and the vehicle can be accessed without prompting any security measures.
Is It Normal If The Red Light Blinks After Locking?
Yes, seeing a red blinking light on dashboard after locking car is normal. This red light indicates that the anti-theft function is active and functioning as intended.
However, if you notice any other unusual signs or symptoms along with the blinking light, or if the light continues to blink for an extended period, your vehicle may have problems.
Why Does Red Light Blink In Car While Driving?
Low Battery/Battery Failure
A blinking red light could be a warning sign of a low battery or a failure. It might signal that the vehicle’s electrical system is not receiving sufficient power, which can lead to various malfunctions.
Lock-Unlock Issues
The blinking red light inside car may refer to problems with the car’s lock and unlock system.
It may suggest a fault in the central locking mechanism, such as a sensor or actuator issue, causing the system to break.
Broken Brake System
This red light could also hint at a problem with the brake system, stemming from low brake fluid, worn brake pads, or a malfunctioning brake sensor.
I also hear some noises when pressing the brake pedal on my car, so paying attention to such issues is crucial for safety reasons.
Improper Tire Pressure
Some vehicles have a tire pressure monitoring system that utilizes a red blinking light on dashboard to signal low tire pressure.
If the light blinks, it could mean that one or more tires have low pressure. This problem can affect handling and fuel efficiency.
Engine Problems
Engine problems can also be problematic if the car alarm light flashes continuously. It may be related to car overheating or low oil levels.
And when my car experienced a malfunctioning sensor, the red light also flashed.
How To Turn The Red Light Off?
Press The Button To Turn Off The Anti-Theft Light
If you want to turn off the blinking red dot on dashboard, follow these steps:
Step 1: Unlock the vehicle using a spare key.
Step 2: Insert the key into the ignition.
Step 3: Turn the key to the “On” position without starting the engine.
Step 4: Look for a button or switch on the dash panel, center console, or near the steering column. Press and hold the lock button/switch to reset the anti-theft red light.
Step 5: Wait for a few seconds or minutes to see if the red light has stopped blinking.
If the light doesn’t turn off, consult the vehicle’s owner’s manual or the manufacturer for specific instructions.
Fix Or Replace Broken Parts
Let’s say you notice the red light blinking while driving; you can consider the below solutions:
- When you have a low battery or battery failure, you can jump-start your vehicle using jumper cables and another vehicle. I always call a roadside service station or a professional to recharge or replace the battery whenever it has some broken signs.
- Check whether the ignition key fob has a weak battery and replace it if necessary. In case the issue persists, inspect the key fob for any damage.
- If your brake has problems, immediately take your car to a certified mechanic or auto repair shop for inspection and repair.
- Adjust the pressure by adding or releasing air to achieve the right pressure.
- Once your vehicle experiences engine problems, it’s best to have it diagnosed and repaired by a qualified mechanic.
