Why does the car alarm randomly beep?

A car alarm may randomly beep due to several reasons, including a low battery, a malfunctioning sensor, or interference from nearby electronic devices. Additionally, if a door or trunk is not fully closed, or if there are issues with the alarm system itself, it may trigger false alarms. Environmental factors, such as extreme temperatures, can also affect the alarm’s performance. Regular maintenance and checks can help prevent these random beeping incidents.
