The transponder detector has an antenna for radiating a power signal to an identification transponder of an unidentified type and for reading a response signal characteristic from the transponder. A plurality of power signal and response signal characteristic parameters associated with transponder communication protocols are serially selected and implemented while an analysis of the response signal characteristic is carried out to determine whether the response signal characteristic matches the selected parameters and to produce an identification match signal. The result of the match signal is displayed as text identifying the transponder make and model number on an LCD display, in the case of a hand-held universal transponder detector. The device is particularly useful for confirming the presence and type of transponders embedded in the head of keys.
