KEY PLUG Meaning and
Definition
-
A key plug refers to a vital component of a lock mechanism that operates through the interaction of various pins, cylinders, and springs. It is a cylindrical or tubular unit typically made of metal, which is designed to act as a receptacle for a key to be inserted. The purpose of a key plug is to receive a properly cut key and to rotate inside the lock cylinder to activate the locking or unlocking mechanism.
The key plug consists of a series of holes or channels known as keyways, precisely aligned to match the grooves or ridges found on a specific key. These keyways are responsible for accepting the key and transferring rotational force to the lock cylinder. When a key is inserted into the key plug and turned, the key's unique pattern of ridges pushes various pins and springs inside the lock mechanism to a specific position allowing the plug to rotate.
Key plugs are found in a wide range of lock types, including padlocks, door locks, and automobile ignition systems. They provide a fundamental level of security by ensuring that only authorized key holders can activate or deactivate the lock. Key plugs can also be rekeyed, allowing a lock to be operated by a new or different key if necessary.
Overall, key plugs act as the intermediary component between the physical key and the internal mechanism of a lock, enabling the secure and efficient operation of various locking systems.

Etymology of KEY PLUG
The term "key plug" is a compound phrase derived from the combination of the words "key" and "plug".
- "Key" has its origin in the Old English word "cǣg" or "cǣge", meaning "a piece of metal that opens or closes a lock". This word has also been influenced by Middle Low German "kieg" and Middle Dutch "kaeye", both having a similar meaning.
- "Plug" comes from the Middle English word "plugge" or "plugg", which referred to a small piece of wood or material used to fill a hole or stop an opening. This word has been linked to the Old English "pluga" meaning "stopper" and the Old French "plogier" meaning "to block or close up".
