Think like a thief. Not all the time obviously, but definitely when it comes to protecting, what for most people is their biggest asset, after their home. Would you want to hang about trying to steal a car with an alarm blaring? A car alarm has two functions, the first is to alert you or people nearby that someone has broken into your car and is probably attempting to steal the car or something in it, such as the car stereo.
Some clarification may be needed on the terminology. Aftermarket, simply means something that is bought for or installed in the car, after the car has left the factory. Furthermore, it is worth noting that an alarm is not the same as an immobilizer. An alarm, simply put, is a siren attached to some sensors or triggers, which will sound, when activated e.g. someone enters the car; breaks a window; tampers with a door lock. An immobilizer, on the other hand, is an electronic gadget fitted to the car, which will prevent the car from starting. If the driver inserts the car’s legitimate key, which usually has a secret microchip inside it, the car will start. Immobilizers are however silent. Both systems have a role to play and can be used together.
It may be worth stating the obvious at this point. If you have not heard your car alarm go off, it is not to say that you don’t have one or that it is not functioning properly. Consult your manual or speak to your car dealer to make sure, before installing something you already have. Someone I was speaking to recently, insisted her brand new, luxury car, did not have an alarm. Clearly, this was untrue. Assuming you see the sense in having a car alarm, the next question is – what are your options? Like all things, the available products range in price and complexity. What you might not know is that you can easily fit an alarm system to your car and save yourself a few dollars. Alarms systems typically start out at around $40 and go well upwards to over $1000 from there. Expect to pay a further $50 – $100 dollars for installation. » Read more: All About Aftermarket Car Alarms
