Why does the car alarm go off by itself?
1 Answers
There are two main reasons why a car alarm may go off by itself: excessive sensitivity and wiring faults. Below are detailed explanations of these causes and their solutions: Excessive Sensitivity A car alarm is a security device installed in vehicles. If someone strikes, impacts, or moves the car, the sensor sends a signal to the controller indicating the vibration intensity. Depending on the strength of the vibration, the controller will emit a warning sound or trigger a full alarm. This serves to deter thieves and alert the vehicle owner. Wiring Faults The car anti-theft alarm is a multifunctional product. It not only provides anti-theft alarm functions but also offers remote control features such as opening/closing the trunk, locking/unlocking doors, opening/closing windows, remote engine start, and engine lock.
