Put your car keys beside your bed at night.
Tell your spouse, your children, your neighbors,
your parents, your Dr's office, the check-out
girl at the market..., everyone you run across. Put
your car keys beside your bed at night.
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.
P.S. I am sending this to everyone I know
because I think it is fantastic. 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.
Please pass this on even IF you've read it
before. It's a reminder.See more

This is a very useful piece. Thanks for this info.
