One funny fact about smart locks is that the oldest electronic lock was invented in the late 1960s by a Spanish locksmith named Linus Yale Jr. He was inspired by the bank-vault locks that he saw while travelling to the US. His invention not only revolutionised home security, but was the forerunner for today's smart locks. Yale's original design is still seen in many of today's smart locks and keypads. Sources:
