What are Deadbolt Locks?

Have you ever heard of deadbolts? Deadbolts are like a household name that usually resonates with most people for having a “strong lock” on a given door. That’s not too far from the truth of what an actual deadbolt lock is. A deadbolt lock, often known as a deadbolt (deadlock), is a lock that requires a key to open and has a square-shaped latch. When it comes to security, deadbolts frequently provide greater levels of protection than doorknob and lever alternatives. Doorknob locks are distinct from deadbolt locks, which frequently come in single- or double-cylinder varieties. Single-cylinder deadbolts have a lock with a keyhole on the outside of the door and an inside flip-turn for locking and unlocking. Although double-sided deadbolts are essentially two independent locks, they are frequently put on buildings where windows are close to locks in houses and businesses. Single cylinder deadbolts are different from double-sided deadbolts in that they cannot be locked. Due to the fact that they must be activated when the door is closed, deadbolts are the most secure locking systems on a conventional door. In order to prevent unauthorized entry, they contain a special locking mechanism integrated into the bolt that cannot be driven back into the door. A spring bolt only sets back 1/2 inch, but a deadbolt sets back 1 inch into the door.

Many people mistakenly believe that double-sided deadbolts have just one lock, but there are actually two independent locks installed on the inside and the exterior, rather than merely a flip-turn lock. Because there are two independent lock cylinders instead of just one, double-sided deadbolts are more expensive than single-sided deadbolts.

Double-sided deadbolts frequently raise fire safety issues for those trying to escape a burning building but are unable to do so because they lack the necessary keys to open the door from the inside out. Double-sided deadbolts are typically used on front doors of homes and businesses with glass entries because criminals frequently smash a window to gain access to a building and then reach inside to pick a lock. Double-sided deadbolts prevent burglars from opening locks with their hands even if they get access through a shattered window. This is because of the fact that there isn't a flip turn they can do; instead, they are met with the identical lock that is on the outside.

The majority of businesses and residences will rely on a deadbolt lock to protect them from trespassers. Homes with entrance doors that are only secured by a doorknob or door lever lock are urged to get in touch with the local locksmith and have a new deadbolt lock installed to increase the security of the door. When opposed to lever locks or doorknob locks, deadbolt locks are far more difficult to kick in since the bolt extends much further into the frame.

The primary difference between a deadbolt lock and a doorknob lock is that they have various latches that provide various degrees of security. A deadbolt latch is intended to further secure the door whereas doorknob and lever latches are designed to make it simple for the user to open and close the door. When identifying which lock latch is which, the shape of the latches makes a significant difference. Deadbolt locks have a roughly square shape, but doorknob and lever lock latches have a slightly slanted shape. The door can close correctly and remain closed until it is operated again thanks to the angle and slant of a doorknob or lever lock latch.
