Why Does the Car Alarm Go Off on Rainy Days?

[Lester]

There are several reasons why a car alarm may go off on rainy days: 1. Low battery voltage: Often, the anti-theft system cannot be deactivated because the battery's current voltage does not meet the system's activation threshold. 2. Static interference: Many anti-theft systems on the market today use random rolling code configurations. The remote controls for these systems are particularly susceptible to static interference. 3. Frozen central locking system: Some domestic vehicles have poor sealing, and as they age, the sealing strips gradually deteriorate. After rain, snow, or car washing, water that seeps into the door seals can flow onto the central locking system. 4. Malfunction: If the anti-theft system malfunctions and the owner cannot immediately identify the issue, the problem can be temporarily resolved by disconnecting the main unit's plug-in board wiring.
