Causes of Car Alarm Not Sounding When Locked & Its Solutions
The issue of car alarms not sounding when locked has led to an increase in car thefts, including theft of items inside cars, in recent years. Therefore, having a car alarm has become an essential accessory.
Car alarms have proven effective in reducing the percentage of thefts occurring in society. Usually, when you lock the car, the alarm will sound if the car has been locked properly.
However, what if the car alarm does not sound when locked? What are the causes, and what are the solutions? To answer all your questions, please pay attention to the following review.
Causes of Car Alarm Not Sounding When Locked
What causes the car alarm not to sound when locked? Here are some of the causes:
1. Central Lock Battery Power is Running Low
When the car alarm is not sounding, do not panic immediately. You can first check the battery of the central lock.
Decreased battery power or a dead battery occurs due to frequent use of the alarm remote. A dead battery is the most likely cause of the car alarm not sounding when locked.
2. Car is in Valet Mode
Did you know that car alarms also have silent and unsilent modes? This mode is often used when the car wants to utilize valet parking services. This service is usually used by parking services in malls, restaurants, hotels, or other public places.
If you are using valet parking services, you inevitably have to loosen your car's security system. Valet parking requires your car to be driven by the parking attendant for a while until the car is parked. Your car alarm not sounding when locked could be because you forgot to change the valet mode back to normal mode.
3. Damage to the Car Alarm System
Is the car remote not functioning after changing the battery? This can usually happen due to damage to the car alarm system. Typically, the damage that causes the car alarm not to sound occurs in the siren or alarm module.
