Curiosities of lock designs and locksmiths
Today, apart from mechanical locks, there are others such as electro-mechanical or electronic, in which the key can be a plastic or PVC card.

Linus Yale Sr and Linus Yale Jr.
The Yale deserve special mention because they are the parents of modern locks. Linus Yale Sr., began designing and manufacturing a series of innovative high security locks at a locksmith shop owned by him in Newport, New York. He specialized in costly handmade bank closures. He invented the bolt cup lock in 1848, which consists of small inner tubes of different lengths to identify the keys. He founded his company Yale in 1840, specialized in high security.
In 1850 his son, Linus Yale Jr., who had joined his father in the business, perfected and patented the cylinder locked by his father’s pins. In 1862, Yale Jr. introduced the Monitor Lock for Banks, which is the starting point for the transition from key locks to lock locks in the banking section.
Yale Jr. was also experimenting with a lock based on a mechanism used by the ancient Egyptians over 4,000 years ago. After patents granted in 1861 and 1865, Yale succeeded in creating his most important invention, the Yale cylinder lock. This lock, which had a pin drum, was similar to the one his father had created, unlike a smaller flat wrench with serrated edges like the ones we still use today.
When inserted into the lock, the key pushes the lower bolts into the correct position, allowing the user to turn the key and open the lock.
