Locks are used in a wide range of commercial and consumer security applications. They offer a simple and effective way to protect property against theft. Even if you’re familiar with the basic design of a typical lock, though, there are probably some things you don’t know about them. Here are six surprising facts about locks.
#1) Locks Were Invented Thousands of Years Ago
While modern technology has led to newer and more effective locks, some of the world’s first locks were created thousands of years ago. In Egypt, archeologists unearthed rudimentary wooden-bolt locks dating back to about 2,000 B.C. It’s believed that these wooden-bolt locks were used on doors. The wooden-bolt locks were similar to the deadbolt locks used on doors today. But instead of metal, they were made of wood.
#2) Locks Consist of Just 3 Components
A typical lock consists of just three components: the body, shackle and locking mechanism. On a padlock, the shackle is the U-shaped piece of metal, whereas the body is the large square- or rectangular-shaped piece component in which the shackle is inserted. Finally, the locking mechanism is the internal component that’s responsible for opening and closing the padlock.
#3) Locks Are Designed to Resist Picking
Many locks are designed with features to resist picking. If a lock is easily picked, it won’t offer much security to the object or property on which it’s used. Commando Locks, however, contain up to 10 security pins to resist picking as well as bumping.
#4) The Term ‘Padlock’ Originated in the 15th Century
It’s unknown exactly who was responsible for coining the term “padlock,” but historians believe the term appeared sometime in the 15th century. The term “padlock” is a combination of the Old English words “pad” and “loc.”
#5) Locks Were a Symbol of Wealth in Ancient Egypt
Throughout much of Ancient Egypt, locks were a symbol of wealth. Everyday citizens couldn’t afford to purchase and install locks. Rather, only upper-class citizens and royalty could afford them. Because of this, locks became a symbol of weather.
#6) Some Locks Use Wireless Technology
You might be surprised to learn that some locks use wireless technology. Bluetooth locks, for example, are designed to open by pairing with a wireless device, such as a smartphone or table. As explained in a previous blog post, however, Bluetooth locks lack the security of high-quality keyed locks.
