It's not accidental that the majority of people will go with dead bolts when it's time for lock replacement. Who can trust simple latches anymore? In spite of the fact that simple latches won't secure properly and won't resist force by perpetrators, the high property crime rates don't leave room for mistakes. The right security door locks must be chosen for all entry points of your house and there is a good reason why dead locks have become very popular.
Apart from the plethora in brands and styles, deadbolt installation will ensure security. Dead bolts are made of hard and very resistant materials, which won't betray your trust if force is inflicted upon them. People insert their key to the lock and unlock the door and fail to see that the unseen complications of the dead bolt mechanism will keep them secure. Don't forget that simple latches won't stand the force of perpetrators and they will retract unlocking the door. Dead bolts won't!
Average dead locks will have one cylinder, which will turn by the key used in the exterior knob. The interior knob will secure the door locks by pressing or turning a button. It will have a keyhole only if the dead bolt has two cylinders. Though, these are usually forbidden for front and back doors, so that people won't be trapped inside the house by trying to find the keys and insert them in the keyway in emergencies.
Dead lock installation will allow you to use a specific key, which will be inserted in the keyway, turn the cylinder that in turn will extract the bolt. The bolt of these locks is the metal tongue, which comes out of the mechanism and inserted in the strike plate on the door frame. It is made of solid material and won't be retracted with force but only with the use of your key. Dead bolts have several pins secured on a shaft and held in place by little springs. The jaws of the keys must match perfectly with the construction of the pins and that's why ensuring quality key replacement is important.
