The History of Locks & Keys
We all use keys in our personal lives every day. You unlock your front door to leave the house, then you use your car keys to get where you’re going. If you’re going to work, you probably use some sort of key to get into the office, and if you’re headed for a workout, you’ll use a lock and key for your gym locker. If you’ve ever wondered about how locks and keys came into being, here are some basics about their history.
Personal property as a concept came into being thousands of years ago, and it necessitated a way to keep one’s personal property out of the hands of others. That’s when locks and keys were first invented.
The earliest evidence of a lock that has been discovered dates back to ancient Assyria. The locks found there were wooden pin locks, similar to modern locks. Pins of different lengths in the locks would only allow the locks to be opened if the right wooden key was inserted.
The Romans began to use metal for locks, but the mechanisms were very similar to the old wooden locks. The metal locks had a keyhole that had a series of concentric plates that would block a key from turning if it wasn’t the right key.
In the 19th century, an enterprising inventor by the name of Linus Yale patented a pin tumbler lock. Yale’s lock used a key with ridges of various heights to align a set of key pins correctly for the lock’s barrel to be turned. This same system is still used in modern locks bearing the Yale name.
In the 20th century, lock designers began to come up with ideas for locks that could be opened without a traditional key. The first of these were push buttons and combination locks. Push button locks are still used in commercial applications to allow access to restricted areas, such as in hospitals or airports.
In recent years, smart technology has begun to be applied to locks. Smart locks allow users to lock or unlock their homes or businesses by using their phones.
The Future of Locks
The use of facial recognition and retina scanners is beginning to be applied to modern locking mechanisms. In the future, you’ll only need to look at your lock to gain access to your home or office.
