Security locks like pad locks have gone a long way. It has evolved into what it is now.
The website United Locksmith shared the history of security locks.
“The oldest known padlocks date back to 500 years before the common era (BCE), and hail from the Roman empire. One of these ancient versions had a rounded iron plate body that was approximately one and a half inches (about four centimeters) by two and a half inches (about 6 centimeters). The body holds a bolt that is manipulated with the use of a key. Instead of a shackle the lock used a chain that would link to the body on one side and fasten by retracting the bolt into the last link in the chain’s other end.”

Gizmodo for its part looked back at the history of pad locks and at the same time gave a glimpse of its future.
“The simple key-and-pin principle has persevered over the century. It spread from Egypt to Greece and eventually to the Roman Empire, where it was further adapted to smaller locks that could secure chests and drawers. Apparently, affluent Romans would wear their keys like rings so that other patricians would know that they were rich enough to own things that needed protection. “

What is no longer surprising is that even lock picking has its own share of history as featured over at Slate.com!
“The pursuit of lock-picking is as old as the lock, which is itself as old as civilization. But in the entire history of the world, there was only one brief moment, lasting about 70 years, where you could put something under lock and key—a chest, a safe, your home—and have complete, unwavering certainty that no intruder could get to it.”
