Deadbolts were invented in 1861. The invention of the deadbolt lock marked a significant advancement in home security.
The deadbolt lock, a common feature in doors worldwide, has a fascinating history. In 1861, Linus Yale Jr., an American mechanical engineer and manufacturer, developed the modern pin tumbler lock, which is the basis for many deadbolt lock types today. Unlike regular latch locks, the deadbolt lock extends a solid metal bar into the door frame, providing enhanced security.
There are several types of deadbolt locks, including single cylinder deadbolts and double cylinder deadbolts. A single cylinder deadbolt operates with a key on the outside and a thumb turn on the inside, while a double cylinder deadbolt requires a key on both sides. This distinction is crucial in understanding the difference between a deadbolt and a deadlock, as well as a deadbolt and a latch.
A deadlock, also known as a dead bolt latch, is a lock that can only be moved to the open position by rotating the key, whereas a latch is a type of lock that can be opened from one side with a key and from the other side with a knob or handle. The price of a deadbolt lock varies based on its type, brand, and additional features.

In a world where security has always been a top priority, the invention of the deadbolt marked a significant advancement in home protection. Prior to its creation, most locks were easily picked or forced open, leaving homes vulnerable to break-ins. The increasing rate of burglaries and home invasions highlighted the need for a more secure locking mechanism, paving the way for the development of the deadbolt.
Linus Yale Jr. and the Pin Tumbler Lock
The modern deadbolt lock owes its existence to Linus Yale Jr., an American mechanical engineer and manufacturer. In 1861, he developed the modern pin tumbler lock, which became the foundation for many deadbolt lock types we use today. Yale’s design was revolutionary as it offered a level of security that was unprecedented at the time.
Evolution of Deadbolt Locks
From Single Cylinder to Double Cylinder
The deadbolt lock has evolved over time to meet the changing needs of homeowners. Initially, single cylinder deadbolts were the most common, operated with a key on the outside and a thumb turn on the inside. However, as burglars became more sophisticated, the double cylinder deadbolt, which requires a key on both sides, was developed to provide an extra layer of security.
Technological Advancements and Smart Deadbolts
In recent years, technological advancements have led to the development of smart deadbolts. These locks can be controlled remotely via a smartphone app, and some even allow homeowners to grant temporary access to guests or service providers. This evolution not only enhances security but also adds a level of convenience that was previously unimaginable.
Types of Deadbolt Locks
Single Cylinder Deadbolts
Single cylinder deadbolts are the most common type of deadbolt lock. They are operated with a key on the outside and a thumb turn on the inside. This design is simple and convenient for everyday use, but it does have a potential security risk. If a burglar can gain access to the inside of your home through a window, they can easily unlock the door from the inside.
Double Cylinder Deadbolts
Double cylinder deadbolts require a key to operate the lock from both the outside and the inside. This design eliminates the security risk associated with single cylinder deadbolts, as a key is required to unlock the door from the inside. However, it does have a potential safety risk in the event of a fire, as you would need a key to exit the home.
Vertical Deadbolts
Vertical deadbolts are a less common type of deadbolt lock, but they offer a high level of security. Instead of extending a horizontal bolt into the door frame, a vertical bolt is extended upwards into a set of rings. This design makes it extremely difficult for a burglar to pry the door open.
Smart Deadbolts
Smart deadbolts are the latest advancement in deadbolt lock technology. They can be controlled remotely via a smartphone app, and some models even allow homeowners to grant temporary access to guests or service providers. Additionally, many smart deadbolts feature built-in alarms that will sound if someone attempts to tamper with the lock.
Comparison of Different Deadbolt Lock Types
| Type | Operation | Security Level | Convenience |
| Single Cylinder | Key outside, thumb turn inside | Medium | High |
| Double Cylinder | Key both sides | High | Medium |
| Vertical | Key outside, thumb turn inside | High | Medium |
| Smart | Smartphone app | High | High |
