In a remote keyless system, a fob is disclosed, which provides the user with selective control of elements in a property in concert with a controller at the property, while the fob is nearby the property. In one example the fob is a wireless portable biometric terminal, which accepts a biometric information having been presented by a user. A transducer generates a digital data based on the biometric information. A data store receives and stores the digital data generated by the transducer. A transmitter is responsive to the digital data having been stored in the data store for broadcasting a signal, at a predetermined frequency and modulated by the stored digital data for reception by the controller, after an interval of time corresponding to a time for the user carrying the wireless portable biometric terminal to have traveled a distance, such that the user may present a predetermined biometric characteristic at a convenient place and time prior to the time of a consequent effect thereof at said property.
