Abstract:
1. A method for validating an authorization for locking and unlocking and/or using an object, comprising the steps of: sending out a request signal by at least one transmit and receive unit at the initiation of a control device, and if a moving and in particular portable code generator receives this request signal, sending back a reply signal, analyzing said reply signal being by the control device following receipt in the transmit and receive unit, and if an authorization is present and confirmed, outputting by the control device at least one control command in the object or motor vehicle, depending on a relevant distance of the code generator from the object or motor vehicle and depending on a location in a relevant detection zone around the object or motor vehicle, carrying out a series of distance measurements, calculating an associated quality value by a mathematical function in each case for the measuring results of said distance measurements, wherein only those measured values which fall below a certain quality value as a threshold value are accepted for an analysis in respect of initiating a distance-related function.
