Abstract
An automotive key fob includes a leaf-style spring positioned within the key fob so that, while a removable key is inserted into the key fob, the removable key engages, and at least partially collapses, the spring thereby reducing movement of the key within the key fob and thereby reducing noise associated with movement of the key within the key fob. The leaf-style spring may be positioned in a spring-surrounding pocket within an external housing of the key fob. The spring-surrounding pocket may be at least partially defined by a wall having a height that is less than a height of the leaf-style spring while the spring is installed within the key fob.
