| | Key fob - Wikipedia, the free encyclopedia |
 | | A fob may be the shape of a symbol or a small representation of an object, or it may be functional itself, such as a small flashlight, calculator, penknife, or bottle opener are common. |
 | | A key fob is a decorative item which many people carry with their keys, on a ring or a chain, often to provide a better grip or to simply make a personal statement. |
 | | Early electric key fobs operated using infrared, so they needed a clear line of sight, and could be copied using a programmable remote control. |
