The best locks in ensuring security are those fitted with dead bolts since they are placed into the steel frame on the inside surface of the door. They derive the name ?dead' from the fact that they cannot be pried open. Some common types of these include the mortise locks, combination locks, rim locks, cylindrical locks, electric locks and padlocks. Padlocks are very popular since they are cheaper in terms of pricing and are not complicated in handling, they require simple skills to handle.The mortise types have a mechanism that is cut into the door while the door latch is screwed on the locking system. They are normally composed of both the dead and spring bolts or either of them. To achieve maximum door security, a dead model that is one inch long is recommended.
