Door Locks

Description
Description

A Door Lock is a mechanical or electronic device that is used to secure a door in a closed position, preventing unauthorized entry. Door lock work by using a mechanism, such as a key, a combination, or a thumb turn, to move a bolt or latch into a locked position. This prevents the door from being opened until the lock is unlocked using the appropriate mechanism.

History
History

The history of door locks can be traced back to ancient civilizations. The earliest known door lock was found in the ruins of the palace of Khorsabad in Mesopotamia and is believed to date back to 704 BC. These early locks were simple wooden bolts that were secured with a wooden key. Over time, locks became more sophisticated, with the use of metal, the introduction of tumblers and pins, and the development of key-operated locks.

In the 19th century, the invention of the cylinder lock, which uses a rotating cylinder to operate the lock, made mass production of locks possible. Today, door locks come in a wide variety of styles and designs, including electronic locks that use keypads or biometric technology to open.

Door locks are embracing the digital age. Today's locks often feature keyless entry, with options like fingerprint scanning or smartphone access, such as the August Smart Lock or Yale Assure. Voice-command integration through devices like Alexa or Google Home is also gaining traction. For those who like both tech and tradition, hybrid models combine traditional keys with digital features. As security needs grow, door locks will keep advancing, ensuring our homes remain safe while offering convenience at our fingertips.

Common Questions
Common Questions
What are the most secure types of door locks?

The most secure types of door locks are the deadbolts, smart locks, and high-security locks. Deadbolts are considered the most secure because they are difficult to pick, bump, or drill. Smart locks use advanced technology and can be controlled with a smartphone or a code, and high-security locks have additional security features such as drill-resistant plates and patented keys.

What should you do if you lose all the keys to a lock?

If you lose all the keys to a lock, it can be a frustrating and potentially costly situation. One option is to hire a locksmith, who can use specialized tools to pick the lock or open it without damaging the lock. However, if you do not have any spare keys and are unable to access the locked space, you may need to replace the lock entirely. This can be more expensive than hiring a locksmith, but it will give you new keys to use. As a last resort, you can drill the lock, however this can damage the lock and make it unusable, but it will allow you access.

Why are door chain locks still used?

Door chains are still used for safety and security, privacy, convenience, cost-effectiveness and aesthetics. They provide an additional layer of security, allowing a person to open the door slightly to see who is outside without fully opening it, they can be useful for people with mobility issues, and they can add an aesthetic touch to a home.

Deadbolt Lock - Round, Oval Cylinder
Style and size comparison drawing of the Deadbolt Lock (Round, Oval Cylinder) compared to other door lock designs

The Deadbolt Lock (Round, Oval Cylinder) is a contemporary door lock featuring a circular base plate and a raised Oval cylinder. In general, deadbolt locks are a type of door lock that use a bolt to secure the door in a closed position. The bolt is operated by a thumb turn or a key and is separate from the lock mechanism. The lock mechanism typically has a cylindrical shape and contains a mechanism that connects to the bolt. The lock is engaged by extending the bolt into a receptacle on the door frame making it more secure and harder to defeat by picking or drilling than other types of locks.

The Deadbolt Lock (Round, Oval Cylinder) has a diameter of 2.64” (67 mm), front depth of .79” (20 mm), and latch depth of 1.06” (27 mm).

Barrel Bolt Lock
Style and size comparison drawing of the Barrel Bolt Lock compared to other door lock designs

A Barrel Bolt Lock, also known as a flush bolt or a slide bolt, is a type of door lock that consists of a metal bolt that slides into a receptacle, or "strike plate," on the door frame to secure the door in a closed position. The lock mechanism is typically a simple design, which consists of a cylindrical metal bolt that is housed within a metal sleeve or "barrel." The barrel is attached to the door and the bolt is extended or retracted by turning a knob or key. The lock itself is a mechanical device and can be simple, but provides a secure locking mechanism that can be used in a variety of applications.

The Barrel Bolt Lock has a plate height of 1.3” (33 mm), plate widths of .63”, 2.52” (16, 64 mm), front depth of .59” (15 mm), and an overall latch depth/height of 1.97” (50 mm).
