The history of lock and the key date back about 4000 years ago when the first lock was invented by the Egyptians. It remains could still be found in the Egyptian empire where there was a dire need of lock.

There is an array of different types of locks with their keys. The houses have different locks whereas the banks make their locks of different form and even the key may not match with anyone. On the other hand is the Maison key system in which the lock permits itself to be opened by several keys. The Maison key system is usually found in apartments, common areas or places such as the main entrance in which people can access the place by their apartment key. But there is an inherent security lack due to which it is usually prohibited in some states or cities. Hence an electronic key system is promoted in these areas so as to save them from any kind of mishap. The Master key system, however, provide a better solution. This system allows that every individual should operate their own locks. No one is responsible and neither can access the locks of anyone by using their key.

Chip keys are very much famous in the formation of cars. They use automatic system in which the key is specifically designed according to the lock which is a circuit that emits radiation.

Moreover, like other keys, the lock will not open by just a mere forcing of a simple or a fault key. The most prominent company, General Motors, has introduced VATS keys which is a Vehicle Anti-theft key in which a resistor is formed on the blade of the key.
