Why Does the Car Still Make Noise After Locking?

[Vincent]

After the vehicle automatically locks, the car alarm system enters an armed state. If the car alarm cannot detect the front-end sensors or if the front-end sensors send an alarm signal, the car alarm will subsequently trigger an alert. Check whether all four doors are properly closed, whether the windows are shut, whether the engine is turned off, and whether the gear is shifted back to the correct position. Here is additional information about the car alarm system: 1. A car alarm is an alert device installed in a vehicle. 2. If someone hits, impacts, or moves the car, the sensors will send a signal to the controller, indicating the intensity of the vibration. 3. Depending on the vibration intensity, the controller will issue a warning or activate a full alarm to deter thieves and notify the owner.
