4. Keep car keys next to your bed while you sleep.
If you hear a suspicious noise and suspect that someone is trying to break in, press the Panic button on your key ring. The car alarm will sound, and the burglar will have no choice but to flee the scene.
12. If you don't have a security system, at least purchase a decal.
If you cannot afford a security system, buy an alarm or patrol service decal to place on your front door. While an accomplished thief is not fooled, decals may deter a less-experienced thief from entering.
13. Join a community-wide crime-prevention program.
Operation Identification is a nationwide project that encourages people to mark their property to combat burglary and theft. In some cities, burglary rates for Operation Identification households were significantly lower than those of non-participants. Also look into groups like Neighbhorhood Watch to see how you can get involved.
