What Causes a Car to Suddenly Sound an Alarm?
1 Answers
The reasons for a car suddenly sounding an alarm are: 1. Alarm sounds after locking: The main driver's door, passenger door, two rear doors, front hood lock, and trunk lock may not be properly closed or the lock switch may be damaged, causing poor contact. This results in the vehicle's alarm system triggering after turning off the engine and locking the car. 2. Sounds inside the car: Once the vehicle is locked, if ultrasonic waves or sounds are detected inside, the car will automatically sound an alarm. For example, after getting out of the car, if there are children, pets, or even flies or mosquitoes inside, the vehicle will emit an alarm sound.
