These days it is getting harder and harder to keep criminals from stealing things. Bank robberies are on the rise and home invasions are even worse. It is not uncommon for a criminal to break into a house and rob it in broad daylight or even while someone is there at night. Regular door locks, where you just use the key that came with the doorknob lock, used to be enough to keep your home secure, but not anymore. To add extra security to your house, because according to Wikipedia: A dead bolt or dead lock (also deadbolt), is a locking mechanism distinct from a spring bolt lock because a deadbolt cannot be moved to the open position except by rotating the lock cylinder. The more common spring bolt lock uses a spring to hold the bolt in place, allowing retraction by applying force to the bolt itself. A deadbolt can therefore make a door more resistant to entry without the correct key.
So take a look at the article below to see which kind of deadbolt you want, the materials you need, and how to install it. Don't make your house an easy target for criminals.
