Why does the car alarm keep going off?

[Danielle]

Reasons and solutions for the car alarm continuously sounding are as follows: Alarm sensitivity: The alarm is overly sensitive, causing it to go off with even the slightest movement around the car. This can be adjusted. Door switch malfunction: If the door switch is faulty, the alarm will sound. It needs to be repaired at a service center. Excessive anti-theft sensor sensitivity: The anti-theft sensor sensitivity is too high, but this can be adjusted. There is a sensitivity adjustment knob on the alarm's vibration sensor, which can be fine-tuned. Alarm working principle: When the sensor is struck or shaken, causing vibration, a small ball rolls inside the chamber. When it rolls away from a smaller secondary electrical contact, the circuit formed by this secondary contact and the central electrical contact is broken. This opens the switch, indicating to the controller that the ball has moved.
