A key holder (10) for holding at least one key body (14) which is pivotably moveable about an axis, when the holder is in use, between a retracted position in which the key body (14) is stored in an inoperable position and an extended position in which the key body (14) is in an operable position; the or each key body may be rotated to one of a number of different angular positions defined by locating means (22). The key holder may act as the handle of a lever for operation of the or each key body (14). The heads of all common key forms may readily be machined so as to lock the or each key body (14) into the key holder (10). |
