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. 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.
