Car’s alarm

What to take to bed with you - not a joke.
Pretty neat idea!
You might never think of it before!
Put your car keys beside your bed at night.

Assuming that you  have a vehicle that has a remote controlled alarm system, tell your spouse, your children, your neighbors, your parents, the Dr's office, the check-out girl at the market, every-one 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 at night and 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, or 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. Perhaps it could save a life or a sexual abuse crime.
It would also be useful for any emergency, such as a heart attack, where you can't reach a phone.
I have suggested to my friend that he should carry his car keys with him in case he falls outside, and his wife doesn't hear him... He can activate the car alarm and then she will know there's a problem.
