What Does It Mean When the Car Alarm Goes Off?
2 Answers
The car alarm going off indicates that the vehicle's anti-theft alarm function has been activated. The anti-theft alarm function means that after the owner remotely locks the doors, the alarm enters a guarded state. If someone attempts to pry open the door or use a key to open it, the alarm will immediately sound. Below are the reasons that may trigger the anti-theft alarm: 1. Doors not properly closed: After parking, if the main driver's door, passenger door, rear doors, front hood lock, or trunk lock are not properly closed or if the lock switch is damaged, causing poor contact, it may trigger the anti-theft system alarm after locking. It is necessary to check the status of the four doors, engine hood, and trunk lid switches and perform repairs or replacements if needed. 2. Detection of movement inside the vehicle: If the vehicle is equipped with an internal monitoring alarm function, after locking, the internal monitoring ultrasonic sensors may detect movement inside the vehicle. To ensure the safety of the vehicle, the alarm will be triggered immediately. If the alarm is triggered without any actual movement inside, it is advisable to visit a repair facility as soon as possible to avoid prolonged false alarms that could damage the battery.
That night when the car alarm suddenly went off loudly, I quickly looked out the window and saw that a neighbor's child had bumped into the car while playing. The alarm likely sounded because the anti-theft system was triggered, which could include sensors detecting vibrations, doors or windows being opened, or accidental remote control operation. Other common causes include aging sensors, weather effects like low temperatures causing malfunctions, or false alarms due to low battery levels. In such situations, I would first ensure safety and not rush outside immediately; use the key button to turn off the alarm and check for any damage to the car body. If false alarms occur frequently, it's advisable to visit a repair shop to adjust the sensitivity or replace components. When parking, avoid obstacles to reduce such incidents. Car alarms are a protective mechanism but also require regular maintenance, such as checking the battery and wiring every six months.
