Default 1UZ engine swap

Somebody has just asked me... When putting a UCF20 engine in another car, apart from using all the usual stuff, motor, transmission, ECU, wiring loom, key and ignition barrel, he asked me if there is a transponder to link the key to the ECU. Does anyone know anything of this ?

'97-00 have transponders in the keys that are coded into the ECU.
