Keys have gone through a lot of material changes according to different types of durability. Certain padlocks require heavy duty protection and therefore may require keys that are tougher, stronger, and maybe a tad bit complex. There is an abundance of strong raw materials available for manufacturing different things to protect your homes, such as steel gates, thicker and more durable doors, and most of all, better keys and locks.
Wood was first used to create large-sized locks and keys in Babylon and Ancient Egypt. While it is great for basic locking and unlocking behavior, but it is very vulnerable to breakage and can be easily broken into pieces with brute force. Metal materials mainly iron and brass were first used during the reign of the Ancient Romans. Not only does this new design makes the older wooden Egyptian locks look smaller and more compact, but it is stronger and have different wards dedicated to different types of locks for a unique set of keys that not everyone has. But, there are also skeleton keys that existed at the same time the Romans made metal locks and keys and was still used for 17 centuries.
These days, aluminum, steel, nickel, iron, and many more types of strong metals are used to mold stronger padlocks and keys. There also exist a plastic set of keys, but these are more commonly used in toys or children’s diaries. The variety of the materials used to make a certain type of key incredibly depends on the cost and the problem. Furthermore, the type of material is also a preference in various countries, such as how Spain and Germany use steel keys, and New Zealand and Austra uses brass. The number of keys that exists today can easily outnumber the number of people living on this Earth. So when the question comes to mind such as “where to get keys made near me”, a keysmith can most probably be found just a few blocks away.
