Pretty neat idea. Never thought of it before.
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.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. 

Keep your cell phone near the car keys by the bed in case you have to dial 911.

The biggest threat that our homes face is from burglars. Home burglaries are quite common and it happens quite randomly. Burglars mostly chose those homes which were accessible with the least effort. Therefore, some important measures should be taken to make the entry into your house extremely difficult.Usually, the first attack made by burglars are at the door. Therefore, the settings of your door is crucial. Set your entrance doors in a proper manner. Both the doors and the frames should be of solid wood. Try to avoid doors with glass panels as it is easier to break into such doors. Do not keep any gap between the door and its frame, and the hinges should always be on the inside. This is because the burglars often strike out the hinge pins to get into the house. Chose proper locks like 1-inch deadbolt for your doors. You can ensure security of sliding glass doors by fixing some bar in the middle of the bottom track.Ideally, a window should be made of burglar-resistant glass with a number of small glass panes instead of a large sheet of glass. The screw head of the windows should be soldered in order to prevent unscrewing of the lock from any small hole made on the windowpane.

Securing your home does not mean that you just have to dig into your pocket and spend on various expensive home security systems. You need to cultivate some habits to prevent any untoward incident at your home. Here are some simple valuable tips, which if you follow can ascertain security of your home:

Before you start staying in a new house, you must change all the locks and tumblers of all the exterior doors of that house. In case you lose the keys of your existing house, then also changing the locks is a must without any delay.

When we go out for a short while, we often keep our homes in an unlocked condition. Burglars are always looking for such opportunities as to when they can enter a house without much obstruction.
Usually, the first thing a burglar does before entering a house is to make the security system inoperable. To counter that, make sure the wiring of your alarm is concealed.
Never keep a set of spare keys in places like inside the mailbox or under the doormat. The safest option is to bury the key in a place in your garden where you can locate it easily later whenever needed.
If you notice anyone roaming around suspiciously in your area of residence, inform your neighbors and security about them.
In case any stranger like a salesman asks for permission to enter your home, check out their ID thoroughly before letting them in. Many times burglars use this excuse to enter our homes and then check out its interiors. They then use the information gathered for a strike later. If you have any doubt, call up their office to find if the person is genuine or not, before letting them in.
Make sure the area near your entrance door is not dark. If required, install proper lighting system.Burglars are always on the look out for empty houses because it helps them carry out their operation without any disruption. The best way to ensure the security of your empty house is to hire a house sitter. When empty, do not keep any evidence of your absence around. It should look like an occupied house all the time. Keep the telephone ring to a very low volume, so that from outside no one can make out from the ring of the unattended phone, something that is a giveaway that the home is empty. You can take the help of timers to put on and off some appliances like radios and lights after regular intervals of time. Thus, your house will appear as an occupied one.When you are away, do not keep any notes for any person from your family or outside. This will just provide detailed information about your whereabouts and duration away, to unwanted people. Guard dogs make a lot of noise when unknown people enter a house. This creates a lot of hindrance for the burglars. Keeping dogs at home is one effective way to guard your house against theft.

The safety of our home, when we are there or away is of utmost importance. Life and property both are valuable. Besides putting the appropriate appliances in place, being careful and alert to any type of eventuality also helps in a long way to protect our homes from any untoward incident.
