Why does my Car alarm activate but no siren?

If your car alarm activates but the siren doesn't sound, it could be due to a few reasons. The siren itself may be malfunctioning or disconnected, preventing it from producing sound. Additionally, the alarm system could have a setting that silences the siren while still triggering other alerts, like flashing lights. Lastly, a drained battery or wiring issues might also impede the siren from functioning properly.
