Have you ever wondered how your car security alarm works? Contrary to what you might think, car alarms are actually pretty simple devices – they’re just a set of sensors connected to a siren.
A car security alarm typically has six parts – a siren (the device responsible for making the noise) and five sensors (window, door, pressure s, shock, motion and tilt sensors). The simplest car security alarms work mechanically – if someone tries to force the door open, for example, the car door sensor sends a signal to the siren, which in turn makes loud sounds. The technology behind door sensors is actually the same technology used in your refrigerator. Notice how your refrigerator lights turn on when you open the door and turns off when you close it? Both technologies are actually simple circuit systems – when someone forces the car door open, the spring pushes the button open and closes the circuit, sending electricity the alarm and siren. Most car security alarms systems have very useful accessories such as a radio receiver for wireless control from a key, and backup batteries that allow alarms to work even when the main power source gives up. Most car security alarms have sirens that are capable of creating distinct sounds so that the owner can pick out a sound pattern and be able to tell if it is his or her car that’s sounding an alarm.

One of the more popular car alarms is the type that is armed with motion or impact sensors that give off a loud sound when somebody gets too near or tries to steal your car. This alarm has been very effective, especially in deterring thieves because the sound reaches anyone within a 120-decibel range and definitely attracts unwanted attention.
However, these types of car alarms were not designed to only give off the sound when a thief is trying to steal your car. They are only designed to go off if someone gets too close or if something comes in contact with your car, — all presumed to be ‘acts of stealing.’ Given this, there are times when your car alarm is activated by accident. This has led to annoying situations that can cause quite a stir in your neighborhood (especially if it happens in the middle of the night). It leaves you scrambling to turn off the alarm. However, turning off the alarm may not be as easy as it seems, because sometimes the alarm system has technical problems.
