• Immediately have the locks changed.  You never know how many contractors, neighbors, or maintenance providers possess copies of the keys.  Although these people may be trustworthy, your keys could get into the wrong hands.
• Change the codes on security systems and garage door openers.  Similar to choosing a password for your computer, make sure your cods aren’t easy to guess: don’t use your house number as the code for your garage.
• Replace the batteries on the smoke alarms.  Buy one fire extinguisher for each level of the house and garage.
• Make sure the house numbers are at least 6-inches tall. They should be clearly visible from the street to help emergency vehicles spot your house should the need ever arise.
