Abstract
Abstract One or more security receptacles, provided for safekeeping keys, include a deposit opening especially configured in a shape corresponding to the longitudinal cross-section of the key handle. A set of ramps oblique and a normally locked horizontal ramp in the receptacle prevent access to the key. The horizontal ramp may be released from its horizontal position by disabling the lock so that the key falls to a lower portion of the receptacle. Disabling of the lock is accomplished by transmitting a coded signal to a receiver incorporated in the lock. Access to the key is then possible, preferably requiring a second key to open the lower portion of the receptacle.
