Avoid isolated places, both day and night. Park your car in well-lighted areas and as close as possible to your destination. In an Apartment or House Ask local police to conduct a safety check of your home. This service is free. Install good locks in doors and windows.
Door chains are unsafe, so use deadbolts for greater security.
Never put personal identification tags on your key ring. Never advertise that you are not at home. Likewise, never advertise that you are home alone. Pull shades or curtains after dark. If you let someone in and then have second thoughts, pretend that you are not alone.
