Tip 1 : Never leave doors or windows unlocked, and never hide a key to your house outside where it can be easily found.
Tip 2 : Use solid core or metal doors that are secured with good quality deadbolt locks. Look for or ask the locksmith for door locks with an ANSI grade 1 rating. Deadbolt locks should have a horizontal bolt at least 1 inch long. With shorter bolts, a burglar can more easily use tools to spread the door frame and open the door.
Tip 3 : Consider using locks that have an internal anti-saw pin that makes it difficult for a thief to saw through the bolt with a hacksaw. Also, some locks come with an anti-drill feature using hardened steel chips inside the lock that will destroy a drill bit in case a burglar tries to drill through the lock.
Tip 4 : The casing, which is the outside housing of the lock, should be made out of hardened steel and be beveled. A hardened steel casing makes the lock more resistant to impact, and the beveling helps prevent a burglar from using a pipe wrench to twist the lock free.
Tip 5 : A metal strike plate is attached to the door jamb to hold the bolt or latch in place. The most common way for a thief to force a door open is to kick it open by kicking at the plate. You can make this harder by using a heavy four-screw high security strike plate. The wood screws used to attach it should be 3 inches long. That way, they will go through the jamb and be anchored in the door frame stud.
Tip 6 : Using at least one long screw in attaching each door hinge will further secure the door against forced entry.
Tip 7 : Treat a door between an attached garage and the house as an outside door and use the same type of locks that you use on the front and back door.
Tip 8 : Any window or glass panel in the door that is closer than 42 inches to the lock should be reinforced with an invisible security film so a burglar can’t break the glass and reach through to unlock the door.
Tip 9 : Windows should be attached to a home security alarm and have locks that operate from the inside so they can be used for escape. Windows can also be made stronger and safer by coating them with an impact-resistant film.
Tip 10 : Another home security measure for windows is to install stops that prevent them from being opened more than 6 inches. If you do, though, everyone in the home needs to know how to remove the stops to make an emergency exit.
