Abstract: This invention relates to the key case that is adapted to be attached to a fixed location on or adjacent a door that is attached to a casing by hinges and has a lock openable with a key. The key case has a sleeve for receiving the conventional hinge pin of an interleaved hinge so that the key case is located in a readily locatable position with respect to the door. The key case has a retracting mechanism with a flexible member attached thereto and the key attached to the free end thereof. Stop means are located within the key case and define a stored position for the key wherein a portion extends through an opening in the case to be gripped by a user and retracted and moved to the lock. The retracting mechanism automatically returns the key to the stored position whenever it is dropped or released.
