3 Causes of Car Alarm Light Not Flashing & Their Solutions

Car accessories such as alarms are very necessary for vehicle owners. However, issues with alarms, such as the cause of the car alarm light not blinking, are often encountered, so solutions need to be sought as to why this happens.

3 Causes of Car Alarm Light Not Blinking

Here are some causes of the car alarm light not blinking, including:

Faulty Alarm System

The first cause is damage to the alarm system. This can occur due to damage to the module part, resulting in no current flowing to control the alarm's operation.

In addition to the module part, a blown fuse and broken electrical circuits can also cause system damage. Even if only one component is damaged, the sensor for activating the indicator light and sound cannot function.

Therefore, when this issue occurs, the solution is to take the car to a workshop for a complete system repair. Because this issue can only be resolved by a mechanic.

In Valet Mode

The car alarm can actually be switched to valet mode. When the alarm is switched to this mode, all security functions of the car will change to a non-active condition.

This mode is used when you use valet parking services at malls, hotels, or other places. This mode generally can completely disable all security features of the car, so check whether the alarm is in valet mode or not.

Door Sensor Not Functioning

Another cause of the vehicle alarm light not blinking is that the sensor on the car door is not functioning. If this sensor is dead, the indicator light and sound will not activate.

When the sensor is dead, the vehicle's sensitivity will increase, causing the siren sound and indicator light to stay on. However, it is also possible that the alarm does not sound and is off, so you need to take the vehicle to a workshop for further inspection.

Causes of Car Alarm Continuously Sounding

In addition to the light not blinking, the alarm can also sound continuously and cannot stop, disrupting comfort. Why does this happen? Here are the causes:

Hood Not Closed Properly

If the alarm siren keeps sounding and cannot stop, check the hood to see if it is still open or not closed properly.

An improperly closed hood can cause the alarm sound to not stop and will continue to sound. The fix is easy, just open and then close the hood again.

After that, lock the hood using the vehicle remote. However, if the hood is already closed properly, it is possible that there is damage to the hood sensor.

Door Not Closed Properly

The most common cause when the alarm sound keeps going is that the door is not closed properly. This condition can occur when the owner is in a hurry when entering or exiting the car, thus not realizing that the door is not closed properly.

Central Lock Remote Battery Dead

Frequent use of the car can also cause the central lock remote battery to die, especially since modern cars now use automatic keys. If the central lock battery is dead, the owner generally has to open the door manually through the keyhole.

Types of Car Alarms

There are several types of vehicle alarms that are easy to find in the market, including:

Auto Lock / Unlock
Remote Controlled Sensor Bypass
Starter Disable Output / Automatic Disable Sensor
Anti Grab Prevention / Anti Scan / Anti Code Grabbing
LED System Status Indicator
Dual Zone Shock Sensor / Two Stage Shock Sensor
GPS Car Alarm

In summary, it can be concluded that the causes of the car alarm light not blinking range from system damage, being in valet mode, to the door sensor not functioning.
