晚上將您的車鑰匙帶到床邊。

如果晚上睡覺時聽到外面有怪聲音，壞人想闖入您的屋子，您可以按下車子的警鈴，車子將會鳴叫，直到電池用盡，或你按下“停止”按鈕。這樣可以嚇退壞人，也可以引起鄰居的注意。

夜間到停車場取車時，也可以將鑰匙拿在手上準備，有情況時馬上按下警鈴。可以減少自己成為被害者的機率。

If you hear a noise outside your home or someone trying to get in your house, just press the panic button for your car. The alarm will be set off, and the horn will continue to sound until either you turn it off or the car battery dies.

This tip came from a neighborhood watch coordinator. Next time you come home for the night and you start to put your keys away, think of this: It's a security alarm system that you probably already have and requires no installation - Test it. It will go off from most everywhere inside your house and will keep honking until your battery runs down or until you reset it with the button on the key fob chain.

It works if you park in your driveway or garage. If your car alarm goes off when someone is trying to break into your house, odds are the burglar/rapist won't stick around.

After a few seconds all the neighbors will be looking out their windows to see who is out there and sure enough the criminal won't want that.

And remember to carry your keys while walking to your car in a parking lot. The alarm can work the same way there. This is something that should really be shared with everyone. Maybe it could save a life or a sexual abuse crime.

Would also be useful for any emergency, such as a heart attack, where you can't reach a phone. My Mom has suggested to my Dad that he carry his car keys with him in case he falls outside and she doesn't hear him. He can activate the car alarm and then she'll know there's a problem.
