Key Cylinder
A key cylinder is a mechanical device used to secure and unlock doors, cabinets, and other objects. It consists of a cylinder that holds a series of pins or tumblers that can only be manipulated with the correct key. When the key is inserted and turned, the pins align to allow the cylinder to rotate, which in turn unlocks the mechanism. Key cylinders come in a variety of shapes and sizes to accommodate different types of locks and applications. They are commonly used in residential, commercial, and industrial settings to provide a secure and reliable means of access control.
