Opening a lock may depend on several different factors such as awhat you have, like a key or key card. What you know, such as acombination and or what you are such as a fingerprint or retinal scan.Many locks use tumbler pins in order to secure their doors orcabinets. A pin tumbler lock uses pins of different heights to stop thelock from opening unless the correct key is uses. Most of these locksare cylinder but may be found in other types of locks as well.One of the first locks ever made was discovered by archaeologists inEmperor's Sargon II's palace in Khorsabad. The lock used the pintumbler principle that is still employed today and has lasted for over4000 years!There is evidence that many civilizations developed locksindependent of each other. The Greek's original lock was much moresimple than Emperor's Sargon II's locks, but still existed. Mostnotably, Homer described a key that moved a bolt in a poem called The Odyssey.The Romans improved upon the Greek's bolt-work by encasing the lockswith iron and using iron or bronze for the key. It would not beuncommon for locksmiths to create intricate designs for the keys theycreated so the keys could be worn as jewelry since most Romans woretoga's without pockets.Lock security did not improve for many centuries. In Europe, most ofthe changes came in the design of the key and locks, with littlechanges to the Roman's core principle.That changed in 1778 when Robert Barren added the pin tumblerprinciple to wards for increased security. He used six tumblers thathad to be lifted to the right height in order for the lock to open. Itprevented the use of small objects to easily open the lock.In 1798 Joseph Bramah improved upon the design by suggesting thatthe tumblers be made uneven so that the key could not be easilyreplicated based on the lock and only a master locksmith would be ableto unlock the mystery of the lock.Jeremiah Chubb created a lock that was a major improvement forlocksmiths. It was tested by renown thieves and locksmiths and no onecould pick it. That was until 1851, when an American locksmith pickedit in less than half an hour.All though technology marches forward, many of the core principlesthat we use in the locksmith industry are built upon the principleslaid forth by these early locksmiths.
