You reduce your chances of being a home invasion victim by making it a practice to lock your doors and windows. Most people are aware of the need to lock their doors while leaving for an extended period; however, many are unaware that it is also vital to lock doors when leaving for a short period. Many times, individuals have entered the wrong building or gone into the wrong apartment door. It’s something I’ve done before. Someone’s personal space is breached in some instances, even if it is usually remedied quickly. Regardless of the historical period, the importance of cabinet locks is never going to fade away.

How do locks work?

The key rotates and moves a bolt into and out of the door frame in almost all simple locks. Although locks like this may be somewhat complex, I’ve simplified the process to the basic minimum to make it easier to understand. The bolt is held in position by tumblers, which are metal levers cut to various diameters to suit the grooves in the key. The tumblers are held in position by springs. When you spin the key, each notch advances one of the tumblers upward. After all the tumblers have moved out of the way, the bolt glides to the right, and the door may open. Almost all mechanical locks have a similar appearance and operate on the same principle, with variable degrees of sophistication. Certain high-security locks are immune to bumping, either because their mechanisms don’t use pin tumblers or because their pin stacks are reinforced with other components that make bumping impossible.

Types of locks

There are many different types of locks in the market. Every day many new, improved locks are making their way to the consumer’s basket. Some of the more popular types are:

  • Knob Locks: The knob lock is the most common type of door lock and the primary form of security for most doors. The lock cylinder is located in the knob rather than the door. Knob locks should not be used on outside doors since they are simple to break into with a hammer or wrench.
  • Deadbolt Locks: This type of lock is the finest defense against burglary or break-in. Lock bolts are moved without the need for spring by rotating a knob or key. Deadbolts feature a one-of-a-kind locking mechanism that can survive hammering, drilling, and physical attacks. With a knife or other hand device, they are impossible to open.


Said, there are many different types of locks on the market, ranging from simple cabinet locks to exceptionally sophisticated deadbolt locks. In any case, locks have been securing our houses and goods for a long time and will continue to do so in the future.
