History of Locks

Locks have provided security in various forms for thousands of years. The earliest known lock and key set was discovered in the ruins of Nineveh, the ancient Assyrian capital. This design, resembling a pin lock, was later adopted by other ancient Mesopotamian civilizations, including the Babylonians, Akkadians, and Sumerians. The design eventually reached ancient Egypt, where the Egyptians adapted it into wooden pin tumbler locks mounted on doors with a wooden post. These locks featured a key and a flat bolt with vertical openings and corresponding pins. To unlock the door, a person inserted the correct key, which lifted the pins and allowed the bolt to slide from the post.

The Romans advanced lock technology by creating metal locks, typically using iron for the locks and bronze for the keys. This has resulted in keys being more frequently found today than locks. There is some debate about the origins of the warded lock, with some attributing its invention to Theodorus of Samos in the 6th century BC, while others credit British artisans. Regardless, by 870 to 900 AD, the first all-metal warded locks had emerged.

Fast forward to the 1700s, locksmiths began creating modern locks thanks to the rapid development of engineering. This allowed them to produce more complex, stronger, and better-quality lock assemblies faster than before. The Industrial Revolution further enabled inventors to create or improve several lock designs. For instance, in 1778, Robert Barron enhanced the lever tumbler lock into a double-acting lever lock. Joseph Bramah, a prominent lock manufacturer in London during the late 1700s, became renowned for producing locks that were extremely difficult to break.

In 1818, Jeremiah Chubb reworked Robert Barron’s lever lock design into the virtually unbreakable Chubb detector lock. He entered it into a British government competition seeking a lock that could only be opened by its designated key. The Chubb lock achieved this and more, featuring a regulator that tripped if someone attempted to use the wrong key or pick it, rendering the lock inoperable until reset with a special key.

Other significant lock innovations of the time included the double-acting pin tumbler lock by American doctor Abraham O. Stansbury in 1805, the burglar-proof safe lock by the Chubb brothers in 1835, an improved double-acting pin tumbler lock by Linus Yale Sr. in 1848, and a key-changeable combination lock by James Sargent in 1857.

Throughout the 20th century, lock technology saw little change beyond improved manufacturing speed and precision. However, significant advancements occurred towards the century’s end. In 1975, Norwegian engineer Tor Sørnes patented the VingCard, the world’s first programmable electronic keycard lock. This technology has since evolved, making keycard locks commonplace in workplaces.

Recent advancements in lock technology include biometrics, RFID tagging, and digital keys. Some locks can now be opened with voice commands or a directive from a smartphone. On Android devices, an OEM lock and unlock feature is often included to protect data during a reboot. While smart lock technologies continue to progress, traditional lock mechanisms remain widely used. It will be interesting to see how lock manufacturers innovate in the future.

Lock Design

A lock is a mechanical device used to secure a door or container, typically opened with a key or a specific sequence of actions known by someone with the correct code.

Lock manufacturers create locking systems to meet either industry standards or custom requirements. They offer a range of standard products produced in large quantities, as well as custom-made options.

Choosing the right type and size of lock for a specific application can be challenging. Fortunately, a reliable lock supplier can assist customers in making this decision. When guiding customers, manufacturers consider several factors, including the need for high security, portability, durability, the number of users, frequency of use, and the speed at which access to the contents is required.

Types of Locks

Locks can be broadly categorized into three types: mechanical, electronic, and biometric.

Mechanical Locks
These are the most common type of locks found on the doors of residential and commercial buildings, as well as on interior doors such as bathrooms, bedrooms, or offices. They are constructed from metal and are operated using either a key or a combination.

Electronic Locks
Electronic locks and locking systems operate without traditional keys, instead using plastic magnetized cards, access passwords, or codes. To unlock a door or safe, an authorized user must insert the keycard into a card reader or enter the correct password or code on a keypad. Once the door is closed, it automatically locks, thanks to a programmed computer chip in the electronic key. Such locks are often used in workplaces with high security requirements, high staff turnover, or frequently changing authorizations.

Biometric Locks
Biometric locks provide the most comprehensive security among all lock types. They may require voice recognition, a retinal scan, or a fingerprint scan to unlock. These advanced locks offer high security and come with a higher price tag, making them ideal for use by government agencies and other organizations, such as banks, that need to restrict access to certain areas.

Miscellaneous
Within these categories, there are numerous other lock types, including padlocks, cylinder locks, mortise locks, deadbolts, spring bolt locks, warded locks, cam locks, vending machine locks, luggage locks, bike locks, child safety locks, window locks, combination locks, lever tumbler locks, disc tumbler locks, wafer tumbler locks, sidebar locks, cable locks, magnetic key locks, and more.

Padlocks consist of a hinge, a chain, and a bar. The bar, or bolt, hinges on one side. To lock, you simply pass the opposite side of the bolt through a chain link.

Mortise locks are highly secure and difficult to break or pick, making them ideal for exterior door security. However, they can be costly to install.

Cylinder locks are suitable for applications requiring less security. Although not as secure as mortise locks, they are easy to change and more affordable.

Deadboltshave a heavy square bolt or round rod made of solid titanium or steel that inserts into a door frame to secure it.

Spring bolt locks are similar to deadbolts, but the bolt can open with applied pressure, as a spring holds it in place. Deadbolts, by contrast, require a key to rotate the bolt open.

Warded locks are one of the oldest types of locks. They use a notched key that slides a bolt until the notches align correctly. While some locks still use keys, many now operate with combinations, keycards, or other keyless devices.

Cam locks locks are commonly used in file cabinets, garage cabinets, and tool chests. They consist of a base and a cam, which acts as the bolt and can be opened with a key or tool.

Vending machine locks are specifically designed for vending machines to prevent unauthorized access to products and money.

Luggage locks are typically small padlocks or combination locks used to secure luggage.

Bike locks come in various forms, such as cable locks and padlocks with case-hardened security chains, depending on how you want to secure your bike.

Child safety locks are used in homes to prevent children from opening dangerous drawers or doors, like a knife drawer. They are usually made from strong plastic.

Window locks provide extra security for windows and are often designed as cam locks for easy installation.

Pound locks are specialized locks used to control water levels in canals, allowing safe passage for watercraft.

Strap locks secure guitar straps for musicians.

Combination locks can be reprogrammed by the user and open only when the correct combination of numbers or letters is entered.

Lever tumbler locks use tumblers to hold a bolt in place. Lifting the tumbler releases the bolt, unlocking the door.

Disc tumbler locks have rotating slotted discs and are highly secure.

Wafer tumbler locks feature locking wafers and are often used in cabinets and cars.

Sidebar locks are advanced lock systems with a radial key and cylindrical code bar. To unlock, the key’s fins actuate the sidebars, aligning them with the code bar.

Cable locks consist of a locking mechanism and a cable with loops on both ends. They are used to deter theft of larger outdoor items, like bicycles.

Magnetic key locks are a newer mechanism, using spring-loaded pins that magnetically repel when the key is inserted, and are gaining popularity.
